Introduction: Knex T.C.R. 51 (Tactical Combat Rifle .51 Cal) Mk4

Picture of Knex T.C.R. 51 (Tactical Combat Rifle .51 Cal) Mk4

This is the 4th version of my tactical combat rifle. It has a stock, and a longer barrel; with a load of power to back the gun up. Lets go the pros and cons shall we?

Very good looking
Very Powerful
High Range 45-65 ft
Iron sights
Comfy to hold

Long barrel will petrude from cover sometimes
 only holds 6 shots

This is probably not going to be the last T.C.R. but no one is sure yet. More knex creations are on the way for sure though.

I have a mod. Try and make the handle holdable to where the pin doesn't snap you in the thumb.

It doesnt snap me in the thumb; and I have fairly large hands. Then again i'm a righty.

I'm also a righty

Thank you too =D What mods do you think this version need?

Yea, you missed 300 and 400.

ya i did thats why i want 500

500th commentor!!!! You win a RPG!!!

yay i have one though lol

Geez. I would have known. But the picture does give me an idea... I think were both glad that you made the 500th comment.

Well good luck with that idea

yay 750th commentor

Actually none, I like it the way it is, but my newest gun Im currently working on will hopefully turn out to be good! Im trying to use all new parts including a new mag, a rare cocking system, and others.

That's good to hear. From what you said about the rare cocking system, sounds liek youre trying to make a true semi auto or fully auto knex gun. I hope that one turns out well like my T.C.R. did.

nah but i plan on doing that next, the system is.... oh well you'll find out later.

Better kept a secret eh? Right now you are my 490th comment (just a little heads up)

it is a secret

I keep my secrets too. But sometimes, they slip out without me realizing.

haha ya

Im at 748


so what are you going to build

I will mod my T.C.R. from Mk4 to the Mk5. And I will remake the MP-605 and make it better.
