Knex T.C.R. 51 (Tactical Combat Rifle .51 Cal) Mk3




About: Hi. I've sold off about 99% of my k'nex, but I still come here to check in on instructables, every 2 weeks or so. I like seeing what's new in the k'nex, and also other sections. I may or may not post my K'n...

This here Version of the T.C.R. is quite good for having no stock and lacking a scope. Lets see the pros and cons, shall we?

Very Powerful
High Range: 45-65 ft
Very reliable
Mag holds 14 rounds
Shoots .51 cal rounds
Elastic Control Wheels
Iron Sights

Will fail to feed the last round about 95% of the time
Could be more accurate

This is the best T.C.R. 51 that has come out since the Mk2. It has my patented E.C.W. system and it is meant for close combat. Buy one today at Ammunation!!!

    I know i might be late to this knex gun stuff but I was wondering if your willing to do instructions for this?

    Honestly not. But you can build Seleziona's dragunov; but dont build the front half of his fake barrel, and dont put a stock on it. You also need the wheels on it if you want the elastics to stay stable. And mine, because it has the wheels, gives it a percise shot.

    This gun came after realizing that blue mullet's shell ejecting sniper rifle was not a very reliable gun at all. Glad you like it!!
