Introduction: TJ-SR-V4

Picture of TJ-SR-V4

Here it is, after a few months! The TJ-SR-v4 is the first sniper rifle (to my knowledge) to use the ball socket connectors as a bullet lock, greatly improving the range to a great 110 ft! The sniper includes:

110 ft range
True trigger
Easy to use

Single shot
Uses a lot of pieces (someone please do a piece count!)
The firing pin is sometimes a pain to pull back as it locks on to the ball connector.

Step 1: Handle and Trigger

One picture, it should be simple enough

Step 2: Body and Stock

You will need leather fingers to do this, but if you don't, just have a go, and use plenty of bandages.

Step 3: The Barrel and Foregrip

Picture of The Barrel and Foregrip

This is easy - it is 12 connectors long, and has the foregrip at the 5th connector from the bottom.

Step 4: Rubberbands, Loading and Firing

Picture of Rubberbands, Loading and Firing

Read the instructions
1.(this is without the sight on) the rubberbands are stretched around the yellow connector and round the firing pin.
2.The trigger band goes where you see it.
3. Pull the firing pin back, slide the bullet in, holding it out slightly, and when it gets to the right place, push it down until it locks into place, then pull the trigger.
You may get even better range if you sharpen the end of the firing pin, but i can't be bothered to mutilate my pieces..
Any questions, just ask!

first of all, killerk did it better than you did it, you didnt sharpen the firing pin like he did. thats why his gun shoots 200 feet, and yours only shoots 110 second, you can take better pictures than this. 4*

dsman195276 (author)DJ Radio2008-10-28

yes, and no. killerk did do this on a pistol. he says that this is the first sniper to use the system, so he is still right. and sharpening the firing pin will not make it any more powerful. it really makes no difference. the reason this only shoots 110 feet is the barrel.

Lowney (author)dsman1952762009-12-05

Sharpening the pin would surely decrease the range? The area of impact is smaller, therefore unless the point hits DEAD centre of the round, the round will not fly perfectly. It does not make much difference, but a difference it makes.

Woo, Physics :D

Golden star cookie for all :D

DJ Radio (author)dsman1952762008-10-28

speaking of Killerk, hes back, take this moment to interrogate him on his SR-v2............

The Jamalam (author)DJ Radio2008-10-29

i already did :D

knexfan9182 (author)The Jamalam2008-10-29

alfpwns (author)knexfan91822008-11-04

it does! lol

DJ Radio (author)dsman1952762008-10-29

i thought the barrel was fake

The Jamalam (author)DJ Radio2008-10-30

the real one

yerjoking (author)dsman1952762008-10-29

He sharpened the ram so as it wouldn't damage the ball joint (I think) because unsharpened and it will just slam into the ball joint, whereas sharpened will glide through, but I don't think it'll increase range that much, about 10 feet or so, not alot really, if any.

The Jamalam (author)dsman1952762008-10-28


The Jamalam (author)DJ Radio2008-10-28

i could, but you can build this from the current pictures. I didn't sharpen the firing pin because it shoots farther without the sharpening.

sammyb (author)The Jamalam2008-10-28

Looks remarkable similar to Mepains Nice going but not as good as the original in my opinion. (Based only on looks because I have yet to build it)

DJ Radio (author)sammyb2008-10-28

this gun has the better grip, mepain's has the better stock. this has better range, and a better trigger (i managed to work out mepain's trigger, its block-true)

razzlekunai (author)DJ Radio2009-05-18

Block-true > true

DJ Radio (author)razzlekunai2009-05-18

Ive built block true guns made by other people, and the triggers broke every once in a while. Plus, Mepain doesnt actually connect the true trigger to the block trigger, you just pull the true trigger, and a lever pops up and knocks the block to the side.

razzlekunai (author)DJ Radio2009-05-18

Your Knex must be cursed. Like my rubberbands.

DJ Radio (author)razzlekunai2009-07-09

yup. Ive tried some slingshots (not killerk's srv2), they all didnt work. The only one I ever got to work was my own OSSR.

what like the dd-27s

sammyb (author)DJ Radio2008-10-28

I was comparing it to killerk's original sniper, but thanks for your comment.I do think that mepains is better ovarall though. By the way that way was a very quick response.

DJ Radio (author)sammyb2008-10-28

oh, lol SAY WHA???????????????

I spammed up your Instructable, now good day poo face two face' moo face, glue face, chew face, loo face, coo face, to face, zoo face, noo face, cuckoo face. Lemon and limes make perfect side dishes. I like it when a man eats a pineapple through his ear. Say hello to the Dunkis for me then send a link to prove that you have done as I wished. Run along and buy some ink pens with cider brewing in your stomach. Ps I like milking cows when the moon is at its fullest, the brandy has a better taste.

The Jamalam (author)sammyb2008-10-28

yes. in fact you do. please get out of my house.

Bartboy (author)The Jamalam2008-10-28

I thought it was my house!!!

stupid drapes, so misleading!

DJ Radio (author)The Jamalam2008-10-28

haha, i guess........................

TwistedParadox (author)DJ Radio2009-04-21

Has anyone actually got any proof that it shoots 200ft apart from KillerK's word?

DJ Radio (author)TwistedParadox2009-04-21

people have built it and shot it 200 feet after their minor mods.

TwistedParadox (author)DJ Radio2009-04-21

Have they got any proof?

DJ Radio (author)TwistedParadox2009-05-29

Killerk posted a vid and measured it.

TwistedParadox (author)DJ Radio2009-05-30

Can you post a link?

DJ Radio (author)TwistedParadox2009-07-09

its on the ible.

The Jamalam (author)DJ Radio2009-03-02

i can't be bothered to mutilate my pieces and if you look i do say that you should. PLOXERD

Lowney (author)2009-10-24

 Didn't the SRv1 use ball joints as a bullet lock? I know the firing mode is different but still...

musicman432 (author)2009-09-23

I don't really get how the ball joint piece goes on. I made it and it goes like 2 feet. Could you post some better pictures?

wizerd 745 (author)2009-08-07

You know what, KillerK's SR-V1 (no longer the best however) is legendary.

hawk295 (author)2009-07-09

cant you explain step 2 a bit more!? wats going on!?

funguy29467 (author)2008-12-03
