This is the 5th version of the T.C.R. 51 series. It is completely refined and ready for a knex war. Lets see some stats shall we?

Extremely Powerful
Very High range 60-70 ft 
Comfy Handle
Good stock
High capacity mag 15-18 rounds
Highly mobile

If not built correctly, it will get a major; almost unfix-able stoppage
Range is a little inconsistent

This is an EPIC gun, and it is ready to blow some people's heads off XD
good little gun you got there :)
Thanks. =) One of my better old guns lol.
I agree!
Yup. This gun was probably the best non-removable magazine I made. Ive wanted to bring it back so many times but ended up making something else. If I ever make another yellow rod assault rifle it will have a removable mag of course and the BSAS mechanism. I already have the mag made, just gotta make the gun itself now. =)
Magizines dont need to be removable! Yeah, building from pictures is hard. =(
Well what I meant by "making something else" is I get a better idea and make that instead. I could easily rebuild this gun if I had to. Its just my preference to have removable mags in guns, makes it cooler; and loading times shorter.
Aye, I agree.
Yup. Might build that assault rifle once I make the upgrades to the TH2BR sitting in my room.
What are the odds of an internal pic in one of these? I kinda need a weapon to back up my VSS Vintorez.... and this gun doesn't seem to take up too many parts, plus has nice range...
It seems pretty good odds, I need time though =D
sounds good :[)
The stock should be easy enough to make from the pics =D
I like stocks like the one on Mk. 1 so... I was going to add that stock to this internal... by the way... if this gun shoots yellow rods its a 5.84 X 87.09mm (or .23 cal) just throwing it out there
omg do u post any instructions to any of ur guns cuz their sick soo cool looking<br>
Yes I did, some of my newer ones got posted lol. But <a href="https://www.instructables.com/id/Knex-AR-12-Prototype-II-How-to-Build/">heres one</a> =D
Like I said, just throwing it out there... whats surprising is that it came out to be a common caliber for rifles... (not the mm one, but the fact that its .23)
What is a gray connector's calibre?
the grey one way connector? its a .31 cal... hence the reason my sidearm is called the UKP .31 (magnum round, it has a green rod connected to the grey one way) I had a forum topic about knex ammo calibers long, long ago, that I think deleted because I was completely wrong... then I looked up the actual conversions, and never posted a new forum topic with the right measurements...
Id like to see a forum topic posted on calibres =D
I'd like to stop getting trigonometry hw... lol... but yea... I'm on spring break here, and its conveniently raining all week, so... maybe I'll get around to it...
me too, I needz to stop getting geometry homework too =D
geometry was a cake walk compared to trigonometry... I had a 108 average in the class... it must have been all those years of building with k'nex... lol...
Trigs and geometry are combined in my school. My grade is 86%. Ive been doing knex for about 5 years now =D
You were building the windmills and motorcycles that came with the sets long before those 5 years right?
Not the windmills, they were L-A-M-E. I started out making cars.
I remember my history of knex... started out at 4 when knex was just getting started... they were putting mini knex sets in paper bags (like the ones m&amp;m's come in) and were putting them in cereal or something like that... then I built the little sets, then got a whole bunch of those little sets and started building bigger things... by 6 I had a crapload of them... and was building windmills... then airplanes... then cars... then working on a stering mechanism for a car around 8... finally got one to work by 9... then by 10-11 knex were a fading trend... middle school was around... and they weren't cool... then I was looking for paper airplane instructions... and found this site :) Decided to look for knex and saw guns (and guns are cool by late middle school) so I started building them... and now I'm almost 16 and still doing this...
Sounds good, Im 15 too =D
We should make a club... and get jackets :)
looks sick man!
It is <strong>lethal</strong>, like my crossbow XD
I am uncertain about the future of a Mk6.
awhhhhhhhh XD
The Mk6 Version is certain to come out, but not for a while.
I can also draw guns pretty well. I liek to draw things too =D
same, i draw alot of guns
I can draw M16's and M4's really well, and im good at sidearms =D
same, and snipers
Im not the best at snipers, but im pretty good.
I always seem to reply to comments quick XD
same XD
I just woke up XD
I got up at 11:15 because I was sooooo tired XD Its 11:31 nao =D
