troubleshooting a gas gun

[Ditch]

i have a dpms lr 308 that i had a conversion done to make it an lrt sass. problem with it is that once the gun heats up it short strokes. it will still eject cartridges but the bolt doesn't come back far enough to strip a new round from the magazine. an ideas?

Re: troubleshooting a gas gun

Try posting in the gunsmithing section. You will probably have better luck.

But it sounds like your gas rings are lose or worn out. I would start with checking those.
