07/20/2013 DISCLAIMER! DO NOT AIM OR SHOOT THIS K'NEX GUN AT PEOPLE, ANIMALS, OR ANYTHING YOU DO NOT INTEND TO HIT. USE AT YOUR OWN RISK. This is my tested and K'nex WAR proven TR8-2013. If this gun which is built entirely out of K'nex is not built exactly as I have pictured IT WILL NOT PERFORM AS I CLAIM IT WILL. This gun was designed and built to shoot fin ammo. I will be showing both how to build the TR8-2013 and fin ammo. With both the gun and the ammo built exactly as pictured only then can I promise you similar results as I have obtained with this gun. As far as modding do as you wish but know that if your gun does not perform as good as I said it could consider that it is your mods that have tampered with the final results. I recommend that if you do attempt to build this gun you place each and every piece in place exactly as I have done so or please do not expect similar results. With all that political mumbo jumbo out of the way lets get to building!

the TR8 was designed and built around my fin ammo
over 4 years of development since first introduced in 2009
tested, retested, improved, and proved reliable and effective at 3 major K'nex WARS
auto rotating turret with ratchet for ease of use and rapid ROF
8 round turret capable of shooting any size rod including oodammo and fin ammo
capable of shooting fin ammo up to 300ft with 6 or 7 size #64 rubber bands

Wow... Thanks, I'm going to build the gun but one more question, how long will it take? I'm not very experienced with building knex guns
Not to be that guy... But how powerful is the gun? I'm thinking on building it but I don't want a cool but weak gun.

Well with 5 size #64 Rubberbands and my fin ammo it will shoot at least 250ft up to 300ft with a max of 7 bands. The gun will shoot threw drywall as well with 5 bands. So I'd say it's the most powerful K'nex gun that has such a quick ROF

to be honest I thought this gun was going to suck but it's actually really good
KILLERK (author)  beebee94716 days ago

Thank you I'm happy you like it! Just curious why initially you thought it would be a crappy gun? Lol

If I were to replace the TR8 turret with a TR-18 turret, do you think it would still function to a similar standard as you intended it to?

KILLERK (author)  Fred the evil puppet1 month ago

with some mods maybe not saying it couldn't be done but the 8 is a great all around balance

Dat Slide...
It's actually amazing.
So good!
KILLERK (author)  TheFoofinator6 months ago
The slide is extremely awesome! I don't use the gun without one now! It makes charging the gun so so much better

try a few of the new mods on step 7! They are inspired from the K'nex War 2013!!! I believe the new trigger will help you out on this one!
KILLERK (author)  pongopeter8267 months ago
take a few more pictures of your gun and I will do my best to help you out. You may need a new black rod for a firing pin or it could have something to due with your trigger either way I would need to see a few more pics of the gun from a bunch of angles.
Congratulations for being selected as a finalist in the Toy Rods and Connectors Contest!

thank you very much! Thank you for your support :)
No problem ;D
Lol, I'm thinking about building this and the Swagboss again. Thanks for posting this man. Love all your work. Oh and sorry for the late comment, I just didn't have an idea of what I should say at first. : P
Kinda late reply, but the Swagboss isn't that great. Uses tons of pieces for not that much power and mostly just a novelty trigger.
I actually happened to like the swagboss when I built it. Sorry to hear you had problems with it. At this point now, I'm just to lazy to build it again.
I didn't have problems. It worked just like it should. But overall it wasn't that impressive, just build a normal TR18.

Also I see my comments are showing up again.

Have you ever tried replaced the dark gray connector on the firing pin and guide with a black hinge piece? You can kind of see what I'm talking about in the picture hopefully. It reduces a lot of friction, making the pin a lot easier to pull back. If facing the right way, it adds to the distance the pin can be pulled back, giving the trigger more room to lock in. It hasn't seemed to decrease performance any, in fact it may even improve ranges by a few feet. I'm not completely sure how reliable it is yet though, so it might not hold up over time.
KILLERK (author)  Mace!8 months ago
I do believe I remember trying this before however it was not as reliable and did not hold up as well under the pressure I usually put my gun under. With fewer bands it may preform decent but overall I would not recommend it. Do you have a picture of the entire gun? Oh by the way thank you for the suggestion I always appreciate ideas even if I've attempted them before or not. You never know till you try
Mace! KILLERK8 months ago
Yeah after 80 times shooting it broke. It worked well for a while though. I do not have any more pictures at the moment but I did add the slide from the TR-18 to it.
