Introduction: Knex OMEN XR

About: I first joined this site in 2008 when I was a bored ignorant teenager with a lot of free time on my hands. Now as of 2019, I’m 23 and in graduate school so I’m permanently inactive here. If you still want to k…
Yes, I ripped off yet another gun name from goldeneye.

This gun was made in about a week when I saw DGM's attempt at a single shot. I decided to make my own bland and uninnovative single shot since there was some stuff from the rectangle that I didn't really like off the bat. I then built this so I could make a single shot that would fit my agenda for a good gun.

One of Oblivitus's comments when he was a mentor to me then struck me, and I decided to borrow parts off of other guns and combine them to make a single shot that would work for me better than others. Innovation was not a priority here, but I have made a new ammo storage container that can hold 6 red rods; it is located on the bottom.

Anyways, here is pros/cons


  • very comfortable
  • true trigger
  • powerful due to the singleshot
  • 60-70 feet with the bands pictured, can shoot in the 80's with #64's
  • lightweight (I can hold it in one hand, but it is recommended you use 2 so that you can aim easier
  • comes with 2 foregrips
  • Brand new ammo holder (holds 6 yellow or red rods)
  • looks cool


  • nothing too new, other than the ammo holder. I am sure you guys dont care because the Rectangle was not new, and you guys still liked it.
  • low ROF due to singleshot/

Enough with my ramblings, let the building begin!

Note- DO NOT substitute any parts here.

Go to step 9 to view a major update with the gun.

Step 1: Stock

This is the stock. Very comfy. Partial credit goes to dutchj for the idea, I did not build his comfort stock part by part, I just used his concept.

1- overview
2- view of the front
3- view of the rear
4- build these 2 parts
5- add the orange part to the stock
6- Add the other part to the blue connector
7- build the firing pin (this early? Yeah.) Remember the tape!

Step 2: Handle

I borrowed this off of Jollex's handle. Fill up the indicated white rods with spacers, and I only put knobs there since I don't have black wheels. Replace the knobs with black wheels please.

1- The handle. Build it
2- Add this part
3- connected
4- connect handle to stock.
5- Make the trigger. Put tape on the blocker part
6- add the trigger.
7- add knex knobs to the indicated rods. I took this picture later on because I forgot the first time.

Move on.

Step 3: Bottom Part/ammo Holder

Its the new ammo holder!

1- Build these panels. Build it EXACTLY like its pictured. One has everything, the other has nothing
2- Build this. This is the second foregrip, and the bottom of the ammo storage container.
3- add it to the one with all the stuff on it.
4- Put the other panel on.
5- Connect to handle. Sorry for blur
6- closeup.
7- Make this. Fill it up with orange connectors. I did not fill it up because I ran out of connectors.
8- Add it to the gun.

Step 4: Barrel

This is Dsman 196276's barrel with mods.

1- Build this. This is the trigger housing.
2- The main barrel.
3- view from the top.
4- Connect the 2 parts.
5- Make this. This is the bottom support and the first foregrip.
6- Add it to the gun.
7- Make this. You should fill it up with oranges, but I ran out.
8- Connect one side to the gun.

Step 5: Connect Barrel to Gun.

I dunno why I made this a separate step, but whatever.

1- Connect pin guide to the barrel, and slide the pin into the barrel.
2- Connect the barrel to the stock. Stick the trigger up in the barrel.
3- Connect the front to the second foregrip.

Step 6: Rubberbands/holding

Add rubberbands to the gun.

1- Add the bands to the trigger
2- Main bands. The ones I put on will get 65-70 feet, #64's will get in the 80's
3- How I hold the gun.

Step 7: Loading and Firing.

Note that I have changed the name and did not bother to change the video to match this.


Reasons this is better than the DD-27:
  • That tan lock in his barrel is not in my gun, so there is less friction
  • better stock
  • cleaner look
  • better trigger
  • Easier to pull the pin back.

Step 8: Credits

Well, I can't really finish this ible without giving credit.

Oodalumps/DGM- inspiration to make this gun
Dutchj- Stock butt (the idea of it, I did not make an exact replica)
Jollex- main handle
Dsman195276- barrel

Back to how much I rule

Step 9: MAJOR UPDATE- Rifled Barrel.

CJ81499 was shooting canadianammo (Red connector, yellow rod) out of my OSSR, and he managed to get the bullet spinning as if it was rifled.  I took a good look at his video, and even though you can't see the round because it shoots so fast, I believe him.

The reason why I believe him is because the red/gray connector is catching on the white rods on the barrel in such a way that it has to turn when it leaves the barrel. This should makes it spin.

A video about how he puts the ammo in the gun:  (Skip to 0:52 to see it, the rest is just random BS)

    Your TCR 51 MK3 is not awesome enough to remove comments.

    Why not? Its a Tactical Combat Rifle that shoots .51 cal. None of those exist.

    .51 cal sucks in Knex terms. So does the idea of a "Tactical combat rifle" that's weighed down in attachments.


    Reply 11 years ago on Introduction

    That is kind of true. But the T.C.R. is the best gun I've made so far. if you made the T.C.R. you would be quite surprised of what it can actually do. And it looks cool. But I am working on a Mk4.

    I don't see how this gun looks anything like the omen xr, here is a picture of the actual gun from the website.

    too bad, a replica would have been quite something.

    WalkableBuffalo seems like someone who knows what he's doing. Also I don't do replicas. I am more performance-based in my builds than looks-based.
