Firstly I would like to say this is an amazing gun, and have rated it 5*.

So I built this yesterday after what I hoped to be a brief return trip to the world of k'nex, and decided to add a few modifications over the weekend...

I have added a reinforced stock similar to the one on your TR8, and a Mepain style scope. I am also thinking about adding another wider barrel onto the end (after the turret) to make it more sniper-ish...

Also, at longer range, using normal ammunition (white rods) do your projectiles swerve right slightly?

thanks you man!
as for the projectiles shooting to the right... i haven't had that issue but experiment around and see what works best for you... if your still having problems get back with me : )
as for the gun you have there... LOOKIN GOOD man : ) lol have a good one bro!

i made this gun and it has a modded front to where you can take the 18 shot turret out and put an 8 shot turret in or just make it single shot and it shoots around 250ft 5*

My TR-18 has an extended stock and a mini-scope. I used your pics and it came out great! I added enough rubber bands to shoot a hole clear through a Pepsi can!!

Feb 4, 2011. 2:39 AMKILLERK (author) says:

Feb 4, 2011. 6:26 PMrookiebuilder says:

Aug 16, 2010. 3:32 PMKILLERK (author) says:

May 27, 2009. 11:09 PMKILLERK (author) says:

Aug 17, 2010. 1:35 PMMace! says:

It might be hard to get pics as most of the grenade ended up on the roof... I'll have to watch the video and thanks.

Aug 18, 2010. 2:27 PMMace! says:

Yes! I got it out of the gutter with a ladder yesterday. I watched the video and it really helps if the band are doubled and I was putting the pin on wrong. I fixed all that and it works like a charm now! Thanks a lot!

Aug 18, 2010. 2:47 PMKILLERK (author) says:

Awesome man! good to hear im happy u like it... the grenade isn't any fun to load up but throwing is always a blast

Sep 20, 2010. 3:30 PMKILLERK (author) says:

this minor mod helps keep the return band attached which is great for shooting at a high ROF
