I really like the trigger on this one, much more reliable and it has less friction.

Thank you I couldn’t agree more. I haven’t built anything in forever but I am happy to see people are still building! I am overall very happy with how the gun turned out. I would love to see some pictures if you have built it! Thanks for the comment.

Sure, I’ll post a couple pictures tomorrow. Definitely one of the best knex guns. Is the range on this one the same as the TR-18?

With 5 or more new size 64 rubber bands this gun will easily shoot fin ammo over 275ft

Yeah, it’s a bit hard to make the fin ammo perfectly. In case you’re wondering, 9 rubber bands is the limit on the pin (mine broke when I put 8 or 9 on it). Could you maybe post the instructions for the SRV-3 sometime?

I had to modify it slightly because the tip of my ram rod broke off for some reason but it still works great

I had to use a different version of the turret because I ran out of the two prong gray

How did everything work out for you!? Hope the instructions were easy to follow and the build works well!

I still find it amusing all the effort you went through to make that striker. Like, how did you even think to do all the things you did? At that rate, I feel like implementing a NAR-esque or rail system would be better. Not that the pin is over-the-top, but it's a little more involved than most people are willing to do, especially for children.

But anyway, glad to see you're still posting updates here as well. I'm currently developing a site in my freetime to hopefully consolidate what remains of the K'nex community across 'ibles, YT, and perhaps elsewhere. I'd like to create guides and other more blog-like posts there to help encourage activity beyond posting instructions. It'll be great if you can help out if I finally ever get around to publishing it. Otherwise, just keep staying active around here and YT so we keep K'nexing alive.

Any updates on the site? At college at the moment, but would love to help in any way possible. I'm working on a CS degree so if you want me to handle any logic for the site or anything I'd be happy to as a side project.

I would build this but my Knex where stolen. The Knex gun community is pretty much dead IMO.

Kyle_M, in some of the pictures i saw some black things on the white rods of the receiver thing, are those neccesary?

They are not 100% needed however they do add strength and support. You can find them at K'nex.com parts and other newer sets.

Just finished the new modifications and the TR8 feels less flimsy and the trigger got less friction. I can’t believe you’re still here updating the gun, too bad everyone left the knex community.

I'm happy to see you like it! Looks like your missing a few things from your pictures. You definitely need to use black rods and the tan rods will add a ton of stability to the design. If you can make the new firing pin too it is a huge upgrade.
