K'NEX Remington R5 RGP (Build)





Introduction: K'NEX Remington R5 RGP (Build)

Derived from the classic AR15, the Remington Defense R5 RGP (Remington Gas Piston) brings a new outlook on the outdated M4 design. With it's video game debut in Call of Duty Ghosts, the Remington R5 is more like a fully automatic sniper rifle than anything else, with its high range and great accuracy.

This K'NEX R5 is true to form with its one-to-one frame, 5.56 magazine width, and great iron sights, this R5 would be a great indoor K'NEX war weapon. Featuring a 15+ round magazine, a pin-guide system, and a modular frame, this is one fun gun to mess around with!


  • Pin guide
  • 45 ft. + range
  • Great iron sights
  • Long sight radius
  • Great pin-pull length
  • Good magazine capacity
  • 1/1 scale body
  • Sturdy chasis
  • Comfortable grip

Lets build it!

Step 1: Left Panel

Pretty self explanatory, check the images for image notes.

Step 2: Stock Internals

Now we'll be working on the stock, go crazy.

Step 3: Main Internals

Here are the internal. If you have any questions, just let me know.

Step 4: The Grip

This is one area where I suggest you do what you want, the grip is only as comfortable as you make it. I made it for looks (as usual) so go crazy.

Step 5: The Last of the Internals and the Right Panel

Here is where you'll be finishing the main body... Pretty simple.

Step 6: The Magazine

The magazine is pretty easy, build the internals around the round you want to shoot.

Step 7: Adding Rubber Bands and Extras

Last step. Follow the pics and/or finish the gun how you want.

Thanks for building my R5 RGP! Let me know how it does for you guys, and as always, if you have any questions, let me know! Thanks guys, you are awesome!

In my heart, the M4A1 will never truly be replaced.

I have the pieces but this gun uses cut pieces

Is there any chance you could make a parts list for this?

Great gun, Red! One of your best rifles, and the pin guide is a great addition.

Red, I love your guns, but this is in a class of its own! Amazing, I don't understand how you can build so many guns at such good quality.

I would also like to know if you use a simple picture reference when building guns, or if you get exact measurments.
