My BIL bought a PredatAR some years back from a gun shop and he has only put maybe 20 rounds thru it, but before shooting it, he bought a Silencerco Omega suppressor and had issues with cycling from the first shot. This was last year and he called me and I tried to explain to him to make sure the PST was in the right position....
Well we finally got together today, for the first time since the C-19 crap and I was surprised to find the rifle does not have a PST? I guess my question is I thought all LT rifles have the PST?
Any way, his rifle was jambing on every round, spent shell hanging halfway out the port and jambed on top of the next round half way into the chamber....
Took the Slash XH buffer and spring out of my 762 OBR and ran a full mag very fast and not one FTF, FTE....he was surprised. I had a similiar issue with my OBR and the Slash XH buffer and spring fixed it.
