I plan on using this forum to show off the SRv3 and get others to help me finish the project. JonnyBgood is right now working on building the SRv3. It is my hope that together along with help from others on the site can continue to make this gun project a more complete more beautiful gun. The gun as is... is capable of shooting 500ft with my fin ammo and bands pictured. If you have the pieces and some eye protection I highly recommend you build the gun and help finish the project! I can not ever take full credit for my work since I learn not only from my past builds and ideas but also from each and everyone on this site and KI. I want to thank everyone for there many ideas and awesome builds that keeps me motivated to come back again and again to check in on the builds. I can't wait to see what this gun becomes. I plan on one day posting an ible once the gun is further along. I hope you all enjoy watching the progress and help be apart of it!

This gun is just so much fun to shoot! It is incredible how far this thing shoots! Shot it outside for the first time this year and it did not disappoint shooting well over 500ft! Considering I designed the gun to do just that I am very pleased with how the gun performs! I'm Excited to bring it to the K'nex war to show off and shoot.

That thing is monstrous. Any idea how much it weighs?

I'm impressed with how much you've done to streamline the design and overcome the problem of that huge draw distance. How long's it been in the works?

I've been working on the v3 for about a year now but only on and off most of the work was completed last summer with just a few improvements here and there since. Still not a completed project but a perfectly fine working one none the less. Thanks for the compliment.


Holy.... My jaw literally dropped when I saw that ratchet go down. I thought at fist that it was big, but then I saw how truly massive that gun is.

yeah it is a big gun! lol super fun to shoot I haven't built much lately busy with life but I love working on that gun

I have been a huge fan of your building stile from day one, and it is really impressive to see how many little ways that you have improved the SRv3. Yet again, when I see videos of you shooting this beast, it makes me want to work on it with you. The problem being that if I were to build this, I wouldn't have many pieces left to build what I really love, replicas. All the same, this is really impressive, and it will be a really cool project once it is fully posted.

Nevertheless, and I know TD has said something like this before, I don't really see the point of the SRv3... And I don't mean to sound rude, but what is the point of a gun that can't (obviously) be used in a K'NEX war, and is not a model or replica of a real gun (XD, it actually kinda looks like a Barret M82A1)? I understand that it has CRAZY power, and this is cool, so far as it goes, but it only really gets super good range (I believe that you said 700 ft.?) at a 45 degree angle. What is its range at a strait angle? I would suggest that you add some more practical features. Things like a bi-pod, a set of iron (LOL, plastic) sights, a under-barrel shotgun (or maybe find a way to strap your TR8 to the SRv3?), stuff of that kind. Again, I don't want to sound rude... the SRv3 is great and all, but really (IMO) impractical.

About the second part of your response, I think it is just for fun. You know, like how far can we get a knex gun to actually shoot? Even if it can't be used in a knex war, nor be a model, that doesn't limit what kinds of gun you can build.

Sure, and I can understand that, but then again, that is kinda like building a K'NEX model (like some of the stuff that dr. richtofen has built) that is not a copy of a real firearm and cannot shoot or make... there really isn't a point.

Even if this gun can shoot up to 700 ft. what is the point of that, if you can't shoot up to 700 ft. accurately...? Again, I don't want to sound mean, but I am just wondering.

Hey I hate to resurrect a dead comment but the range of this thing is completely believable. I have my own version of the SR-V3 and from the power it demonstrates indoors ( with the regular bands I have on it ) is unlike anything on this site.

Seeing this work in person, definitely a must.

You should give it a try. I'll get you some pics on how mine works ( granted I find time to do it ) so maybe you can give it a try yourself.
