Ridiculous feedneck blowback

[k_obeastly]

this may be a great candidate for an oval hole on the trigger plate.

Just went through a mid block headache. No blowback having 90 duro number 15s on the bolt.

My set up is Phat Rat valve, Shocktech pnues, ID hammer and green/green Docfire Springs, and an ID bolt. The sled is 1/16th inch is from body in the full forward position. I an shooting a consistant 290 at 225 psi through the HPR.

Good luck.

Thanks again everyone. I stepped away from it for bit.

I adjusted the sled/bolt pin forward some more, maybe 1/16 from the body.

I turned to the 3 way and I think it has something to do with that. It’s at a point where I have no blowback but it leaks bad out of the top 3 way hole closest to the front block if I hold the trigger. A fraction of a turn will stop it from leaking when holding the trigger but the blowback returns.

Velocity is still down though. I’ll mess with some springs to see if that helps with velocity and the blowback as some have mentioned.

Good evening, I think I got this sorted… I put the pump kit back on lol. Scooped up a Prostock on eBay for cheap which will be the home for my new pneumatics and all is right in the world again. I got it close to not blowing back with some thicker orings on the middle and back of the bolt, but ran into the orings dragging when I shot a little faster, and 3 or 4 out of 10 shots would still blowback.

Just wanted to say thank you again to everyone who responded!
