View Full Version : Chopping???
03-12-2006, 08:58 PM
I am having a problem with my stock TL-X, IT IS CHOPPING LIKE CRAZY :mad: It's a brand new gun, and the bolt is scratch free. I lube the O-Rings everytime before I play. I don't shoot fast at all, so the hopper is not an issue. Everytime I play, a ball chops and shoots paint back into feed neck and in the hopper, which eventually ends up chopping more balls, and making a huge mess. Then the accuracy is so terrible that I can't even play. Is this a blowback issue? The paint I use is brand new; RPS Big Ball.
Also, I was thinking about upgrading to a shocktech delrin bolt. Would this help with my chopping problem?
Any feedback would be greatly appreciated, THANKS!!!!!!

Otter has a few tips for you to try. ball chopping info (http://www.ottersccustoms.com/trouble.html#chopping)
If those don't help check back here.

I'd say most likely its the paint. I've never heard anything good about Big Ball.
The shocktech bolt is a decent bolt but not designed to help prevent chopping. For that you'd need an ACS bolt.

I checked the otter site and still no help.

this does sound like blowback if the paints ending up in your feedneck ... Try drilling some holes in the feedneck/elbow to relieve the pressure ...
Whats your FPS set at ?? .. since if it wasn't too low .. i'd say switch to a lighter mainspring .. would reduce blowback a bit.
A bolt with a o-ring on the front would also help .. if not that i'd just say get a forcefeed hopper :)

I've spent all day trying to diagnos my gun, and I came to the conclusion that it was a bad case of blowback. So I drilled some holes in the feedneck to let more air escape, and I drilled a hole into the lid of the hopper (It's one of the regular hoppers, not a force feed). Hopefully, this will fix the problem.
I am shooting at 275 FPS, but what does this have to do with blowback? I don't quite understand.
Thanks for the help.

well .. blowback ... happens because air tends to take the easiest way out ... If there's space to pass through the feedneck .. it will
Only way to really relieve this is to lower your psi or make relieve holes ... but you could always get a new bolt that has o-rings in the front to prevent this.
I have seen a anti-blowback mod ... which actually sucked the air in .. but i don't quite remember the site .. if i come across it i'll tell you about it :)

Thanks for the reply. Could you show me an example of this special kind of bolt with an O-Ring at the tip of it. Becasue I have never seen a bolt like this.
