Introduction: How to Clean Your New Tec 9

Picture of How to Clean Your New Tec 9

Tec-9 Disassembly / AB-10 Disassembly / Tec-DC9 Disassembly

Firearm shown is an AB-10, but the basic process is identical for all of the Interarms 9mm Tec-series weapons to the best of my knowledge. It's also useful for the Kimel/AA Arms AP-9 series as well as they're close, close cousins of the Tec series.

A basic level of competence is assumed in these instructions, as well as sobriety, legal possession of said weapon, et cetera. A sense of humor is also very, very helpful.

For the purposes of this web page, only the basic maintenance required to clean, lube, and keep your Tec-series "pistol" operating will be covered. We're interested in field-stripping and routine maintenance here, not taking apart the cap-gun lower receiver trigger mechanism or the like.

If you're unsure of yourself or your skills, take the weapon to a competent gunsmith and ask them to show this to you. If you damage yourself, your property, your domestic partner, your low-rider, wall of graffiti, or fellow gang members, it's your fault. Use these instructions at your own risk - they're worth exactly what you paid for them.

Step 1: Step 1: Get Your Gun

Picture of Step 1: Get Your Gun

You'll need the following to complete the disassembly of your firearm:

- The weapon itself.
- Slot-head screwdriver.
- Phillips screwdriver.
- Hammer or rubber mallet.
- Cleaning supplies + weapon lubricant (WD-40, Rem-Oil, etc.)
- A flat surface upon which to work.
- A parts tray, dinner bowl, or something to hold the small, easily-lost parts as you go.

Step 2: Step 2: Make Sure That Sucker's Unloaded.

Picture of Step 2: Make Sure That Sucker's Unloaded.

Remove your magazine. Pull back bolt handle and visually inspect chamber to make sure that there's no forgotten bullet lurking inside, waiting to be eaten by a grue.

If you're the paranoid type, hide all magazines and 9mm ammunition in another room while you disassemble the gun. If you're not, bully for you.

Step 3: Step 3: Remove Retaining Bolt From Frame

Picture of Step 3: Remove Retaining Bolt From Frame

Before doing anything else, make sure the gun's not in the safe position - cocking handle pushed in - I have no idea if anything bad happens if you disassemble it when the safety is on. Of course, this assumes that someone would actually use the safety on this weapon.

Using your handy Phillips screwdriver, gunsmith punch, or just about any metal object that's easily tapped and is smaller in size than the front retaining pin on the weapon, remove the front retaining bolt from the frame. It'll move slowly at first, and be careful to not damage your genuine plastic receiver. Once it's out about halfway, you may be able to pull the pin out with your fingers - if not, work it out slowly so the last tap doesn't send the little piece flying all over the room.

There's no trick to removing this bolt - it isn't spring loaded or required to be turned to a particular angle, or anything of the sort.

Take the retaining bolt and put it somewhere safe, like the parts tray recommended above. You don't want to have to buy another one.

Step 4: Step 4: Remove Upper Receiver Tube From Lower Receiver.

Picture of Step 4: Remove Upper Receiver Tube From Lower Receiver.

Once the retaining pin is removed from the frampe, pull the upper receiver tube away form the lower receiver up, away, and forward of the magazine well. It'll come out easily enough.

Expect the strap lanyard to fall out if you're not paying attention. Put the strap lanyard in your parts tray.

Step 5: Step 5. Unscrew Upper Receiver Cover

Picture of Step 5. Unscrew Upper Receiver Cover

Firmly grasp the receiver tube in your hand and examine the rear end. Ask it out on a date. When it respectfully declines, you'll likely note the notch for inserting a handy tool (like a slotted screwdriver) to facilitate rear cover removal.

It'll take a few turns of the rear receiver cover to get it to fully disassemble. There's not much to worry about here - unlike other firearms I've taken apart over the years, there isn't a whole lot of pressure in the receiver tube and its springs, so pieces are unlikely to enter low earth orbit.

When it's done, you'll have something that looks like the second picture.

Put the rear receiver cover in your parts tray. I don't think the plastic lower receiver is strong enough to stop the rearward motion of the bolt when fired without it.

Step 6: Step 6: Remove Charging Handle From Bolt.

Picture of Step 6: Remove Charging Handle From Bolt.

With the rear receiver cover removed from the tube, and the recoil and operating springs hanging haphazardly out the rear of the upper receiver, move the bolt handle back as far as it goes.

Pull the charging handle out away from the receiver and out from the bolt. There's a small ball-bearing in the charging handle itself that will give a little resistance, and you might have to move the bolt a little forward or back to remove the charging handle fully from the bolt.

Step 7: Step 7: Remove Bolt From Receiver.

Picture of Step 7: Remove Bolt From Receiver.

Guide the recoil and operating spring out of the receiver tube, and remove it and the bolt from the receiver tube. When it's done, you'll have a bolt trailed by a pair of springs. Depending on your luck, desire for further cleaning, et cetera, the firing pin and firing pin retaining mechanism may or may not remove themselves from the bolt.

The photo above shows the firing pin and firing pin retaining mechanism removed from the bolt - to re-install it, place the firing pin the center channel hole of the bolt, and place the spring in the rear opening of the firing pin retaining mechanism.

Depending on whether or not you've ever taken the thing apart in its life, the bolt and bolt parts are likely to be very well slathered in packing grease. Remove it, and you'll have a much smoother-cycling and operating firearm, not to mention one that fires a little faster.

And firing faster is the real reason you own one of these babies, right?

Step 8: Step 8: Clean Barrel, Feed Ramp, and Receiver Tube

Picture of Step 8: Clean Barrel, Feed Ramp, and Receiver Tube

Now you'll likely want to wipe down the inner parts of the receiver tube, removing deposits of packing grease, burned powder, primers, cocaine residue from the previous drug dealing owner, or whatever else may inhabit the tube.

Pay special attention, as with any firearm, to the chamber area, feed ramp, and barrel. You may or may not need to brush out your barrel - chances are not, and it's been as easy in my experience to clean out the chamber and barrel with Q-Tips or the like as it is to use a regular pistol brush due to the short barrel and chamber length of the weapon.

Lightly lube the interior of the tube with a quality firearm lubricant (Rem-Oil, WD-40, etc), and wipe away excess.

Step 9: Step 9: Reassemble the Thing

Picture of Step 9: Reassemble the Thing

Place the bolt and spring mechanism back in the upper receiver tube.

Before re-fastening the rear receiver tube cover, line up the hole in the bolt for the charging handle and re-insert the charging handle. You won't be able to do it once the cover is re-installed, so don't forget.

Once you've re-assembled the upper receiver, take the strap lanyard and place it on the rear of the receiver tube. Insert the upper receiver tube and strap lanyard into the lower receiver in the opposite direction that you removed it, slowly and carefully.

Visually align the upper and lower receiver so that you can re-insert the retaining bolt holding the firearm together. If you can see daylight through the hole, and it's perfectly round, reinsert the retaining bolt. Tap lightly with your hammer, mallet, etc. to re-seat the retaining bolt in the receiver, and make sure it's back in fully.

Pull back the bolt handle to visually inspect the chamber to make sure once again it's not loaded, place the safety in the fire position, and point the firearm away from things you'd rather not destroy, maim, kill, or frighten. Pull the trigger to test for function - if it dry fires as usual, then you're most likely good to go.

Reinsert magazine if desired.

You're done.

If I was concerned about whether or not you cared about political correctness and "NRA-approved gun safety", I'd suggest locking up your Tec-9 in an unloaded manner with an approved gun lock. However, you own a Tec-9 - I somehow think you'll leave it on the desk just like me.

Just don't let children near it. They already think it looks like a cap gun.


knoxarama (author)2009-03-25

seriously, why would you need one of these? a shotgun, a pistol, a rifle and airsofts, yes, but a freakin' uzi? you can't hunt with, its not great target practice, and it's overkill for defence. Don't take me wrong, the government can take my guns from from my cold dead hands, but yeah.

tenaciousbd (author)knoxarama2009-03-27

No one needs one of these, in my personal opinion, no one needs any gun. I have one because I want one, and I enjoy shooting it. I'm not even preoccupied with self defense (not defence), Speaking of lack of education, it is a Intratec 9DC. Not an uzi. It is a cheap, mean looking, inaccurate, semi-automatic 9mm. The only thing about it that may be considered "overkill" is the fact that it can hold up a 50 round clip, which, if you go out to the mountains and just blast away at random targets, beer bottles, boxes, and small unsuspecting, undeserving animals like we do, you can definitely see the benefits of not having to reload after ever 20 rounds. (We're also very lazy) I hope this was informative enough of a comment. Please, think before you go firing off about things you know nothing about.

knoxarama (author)tenaciousbd2009-03-28

as i do know what i'm talking about, and when i said 'uzi', i only meant that as a general term as it related to it. i know it wasn't. but fine, your logic is reasonable. don't shoot the animals up to much though; you'll ruin the pelt, if you decide to sking it and wmake a hat from it or something.

raberens (author)knoxarama2009-05-03

I just picked up a tec AB10, it was cheap and I shot it today and it was fun!!! I was also surprised in that at 30 ft. which is a true defensive distance it was quite accurate. even rapid firing I put them into a paper plate size group

Coffee bean (author)raberens2009-06-23

What is the price on those? Plus the $200 tax and ammo!

Lokisgodhi (author)Coffee bean2015-12-03

It's not a sbr, it's a pistol. It has no shoulder stock. So why would a tax stamp be needed?

korgoth25 (author)Coffee bean2011-06-17

I dont know the price on them but a $200 tax!!! where do you live for that? up here in NH all we have to do is pay for ammo and the gun. LIVE FREE OR DIE!!!!

Coffee bean (author)korgoth252011-06-17

IIRC I was referring to a short barreled rifle. That has a $200 tax to matter what state you are in. You can thank the NFA for that.

korgoth25 (author)Coffee bean2011-06-17

really? wow that sucks. oh well at least californias gun laws arent for the U.S. otherwise getting that baby would be ny impossible lol

Coffee bean (author)korgoth252011-06-17

Yeah NFA sucks. I would never move to Commiefornia.

korgoth25 (author)Coffee bean2011-10-12

speaking of uzis, i just shot my first 9mm uzi today (not a mac10) (but the larger isreali version) was fun, barely any kick but on full auto it goes everywhere

Coffee bean (author)korgoth252011-10-12

I've shot one as well the weight of the whole thing really surprised me and like you said it's very controllable IMO. The one I shot(full auto) according to the owner costed him $8000. Needless to say I handled it very gently.

sbeltz (author)Coffee bean2011-10-12

It is registered as a handgun, not an SBR.

Coffee bean (author)sbeltz2011-10-12

Correct I think I was talking about an Uzi at the time but to be honest it was a long time ago so I could be wrong.

Whether you need a firearm or not is dependant on where you live. If you live in the wilderness of Alaska with 7 sled dogs and a bear is attacking them, what are you going to do without a 30-06? It's pretty hard to take down a bear with anything smaller than a 30-06. Just something to keep in mind.

tenaciousbd (author)dla8882009-10-15

Of course, the most likely of scenarios...  by the way, is seventhe standard number of sled dogs generally used to tote a fat assAlaskan around?  Or does it depend on the breed of the dog?  Iam genuinely curious about this, how ever, there is no insructable ondog sledding.  One of you needs to get on this for me STAT. Seriously, wipe that stupid grin off of your face and start your research.

ilpug (author)knoxarama2010-12-26

the tec nine isnt good for anything. thats the point. its only use its to prove your stupidity and pop culture passion to your fellow degenerates.

dla888 (author)knoxarama2009-09-27

You would need a fully automatic firearm because the people you are defending yourself against are carrying AK-47's, FN-FALs, M-16s, M4s, M-14s, and other automatic firearms that they have obtained throught the black market. If you don't believe me, there is a Russian black market arms dealer named Viktor Bout. He'll sell you an AK no questions asked.

littlebastard (author)knoxarama2009-09-18

its not overkill for defense when alot of the people you need to defend yourself from are carrying AK-47s, micro uzis and AR-15s.

Zigamafa (author)knoxarama2009-06-25

some people get firearms like these for the novelty (much like how some people will buy swords, old vintage movie posters or what have you).

Miles Tails Prower (author)2009-02-14

I wish I had a Tec-9...

if you've ever shot any gun you will know pistols are inaccurate shooting in semi-auto. do you just want it "cause it looks gangsta dawg"?

You're still ignorant. Its not a spelling bee its about guns

oniman7 (author)corey_caffeine2009-05-24

Not true. The navy "expert" qualification is hitting a barrel with a pistol(used to be a .45, now I think it's a 9mm) from 250 feet away, while it's bobbing up and down with the waves. Not being old enough to own a gun myself, I have to trust my father on this one. However, he earned the expert qualification with both an M1917 (modified M1911) and an M14.

corey_caffeine (author)oniman72009-05-25

it's a dice roll, trust me

also have you ever shot?

I own tec 9 for about 20 years now. I'm about to shoot it now. Burning time on here while at the gun range waiting on a friend. For such a cheap gun they are way more accurate than i thought they would be. Do you know any other guns that cheap that perform like they do? Plenty of capacity and accurate enough.

The fact that it can be done consistently says something else to me, but maybe a Tec 9's a bit different. I haven't shot anything but airsoft, but I know a fair bit about guns and shooting. Waiting till I turn 18. Gonna move to the place with the least strict gun laws, but a house, and mount two M60's (with a trigger lock, of course) on the roof. That's my dream, anyways :)

oniman7 (author)oniman72009-05-26

By the way, did you know that the two kids in the Columbine used Tec 9's?

JV3 (author)oniman72013-02-22

also, they wore Levis jeans.
Levis Jeans are insensitive

JuCo (author)oniman72011-04-06

i think they were also wearing shoes.

Coffee bean (author)oniman72009-06-23

No I'm pretty sure they were hi point carbines(9mm).

no, one of them used a tec-9

Sorry, did a google at some point there was a tec-9 used. They may have had more than one gun. That being said it really wouldn't had made a difference what guns they used it's about the people not the guns.

JV3 (author)corey_caffeine2013-02-22

sorry man, but semi auto is second only to bolt actions. i think the term your after is full auto.
semi auto discharges one round per trigger pull
full auto continues to fire as long as you depress the trigger.

the only thing that makes semi autos is lack of self restraint.

"if you've ever shot any gun you will know pistols are inaccurate shooting in semi-auto." What kind of BS comment is that? If it's a clip fed weapon it's at least semi-auto. Even a DA revolver behaves like a semi-auto(at least for 6 shots). I don't know how you shoot or what you shoot that would cause you to make a ridiculous statement like that, but I know it can't be attributed to your experience or competence at any shooting sport. The only thing that will protect ALL our second amendment rights is eliminating ignorance

I shall now provide a counter-statement

First off, it isn't "clip fed," it is fed by a magazine.

Secondly, you know nothing of my competence, and I shall have you know I can hit a target the size of a dollar bill at 200 yards with an M1 Carbine (magazine fed rifle).

Lastly, you forgot a period in that sentence.

When you say semi-auto or do you just mean when rapidly firing?

Also not all magazine fed weapons are semi auto. ~pump action shot guns ~lever action carbines ~several bolt actions have magazines detachable and not

No, but guns are fun to shoot with. And especially in fully auto.

-JESUS- (author)corey_caffeine2009-03-08

Lol true... and in all the movies they shoot the gun sideways, but the recoil will be going to the left, and the casings will be getting thrown in your face

Look at my 'ible xD

2quickvr6 (author)2010-12-30

This gun is great! Just have to know how to take care of it and handle it....

Hades di Angelo (author)2010-01-23

what is the dang price,message me

when you find the price

brandon borick (author)2010-01-07

is it me or are tec 9s just to flashy i mean a glock 17 with a 32 round dose the same thand ecept its mor acurat un like my spelling

you know what they say a 9mm is right
a 45. set to stun

unaffiliatedperson (author)2009-11-21

have you bump fired it?

unaffiliatedperson (author)2009-08-17

do hollow points jam this? my friend was going to buy one of these a while back but instead got a pistol tazer for 30 bux

Hollow points shouldn't cause it to jam anymore than it does with 9mm rounds your parents buy you at Walmart. The point of proper maintenance is to keep it functional and retain its value. That way, it's not worthless as a $30 stungun. Hope your friend gets over his fear of being raped.
