Introduction: Knex T.C.R. 51 (Tactical Combat Rifle .51 Cal) Mk1

Picture of Knex T.C.R. 51 (Tactical Combat Rifle .51 Cal) Mk1

This is the first decent gun I have made in quite a while. It is based off of a Dragunov, Barret M82 .50 cal, and an older rifle yo would have found in WWII. This is the best rifle I have made EVER!!!

Very Powerful
High Range 40-50 ft
Does some damage
Shoots yello rods
Red Dot Sight
Brutally strong trigger

Not fully my idea of a gun

This is the new, powerful, awesome combat rifle by me and credit goes out to: Seleziona!!!

Mk2 Version
Mk3 Version
Mk4 Version
Mk5 Version

Very nice. I would level the top off with a rail. It looks a bit off that the barrel is fatter than the gun itself.

Good idea. Im modding it with a sniper scope, M4 stock, rubber band control system, and yea a rail for the top of the gun. Did you see blue mullets new shell ejecting rifle?

Yes. I've made that gun twice. It's Ok, but it could be improved.

I know what you mean. Things that need improved for my version are the power and the fake barrel. and I tried a rail, but it got in the way of the scope's view. And you have amde it TWICE!?

It isn't his, look what he said, he's just making instructions for it. It was posted 2 years ago.

its cool, but alot of it looks like you have just taken seleziona's dragunov, shortened it and changed the stock, so this is not all your work

That is the truth of what you said. Credit has gone to Seleziona, read the bottom of the description. Im glad you like it too!!!

oh ok i didnt see the credit. its cool

Yp. I Honestly like your LMG model the best because My favorite real gun is the M60E4.
