Introduction: K'NEX Gun: Red Competitor (R4)

About: K'NEX gun builder here at Instructables. More or less retired from the community, but I still pop in now and again.
Some time ago, JonnyBGood and I were planning on doing a collaboration on a FAD. Needless to say, that fell through. The FAD just had too many weird edges and bumps. Then we thought about doing a concept gun, and decided to mod the flipping snap out of the K2 V.2 (see pic #14). JBG did not succeed as well as I did (not from lack of trying), and these are the pics to my burst-fire rifle, the Red Competitor / R4.

With a 10 round magazine, a ROF of of 4 rounds per second, and a comfortable body and handle, this is one of my most innovative guns.

Improvements over the K2 V.2 include:
  • Comfort (the K2 V.2 was really uncomfortable)
  • Speed (I think that I can pump the Red Competitor / R4 faster)
  • Magazine (the K2 V.2 had a TR8)
  • Piece usage (the R4 uses a significantly less amount of parts)

Enjoy!
