Idk if this really counts as gunsmithing, but I think it fits here.
I have a Palmetto PA10 I've been tinkering with for a year or so. I got it to run reliably, and relatively accurate for what it is.
Recently decided to upgrade to a Ballistic Advantage 16" barrel, carbine gas system. SA adjustable gas block. PSA BCG, standard charging handle, enhanced
buffer/spring, and MI Gen 2 free float.
Tested it out today, and right off the bat had issues with inserting a magazine (ASC steel) on a closed bolt. Locked it back, inserted the mag, and hit the release. No bang. The bolt failed to go into battery, and was stuck. Had to use both hands and put the stock into my chest to get it open. I'm going to plane this one on me, as there bolt was dry as could be. Lubed it up and the problem decreased, but did happen again.
Switched over to Pmags and much better fit of the mags. Had a few issues while adjusting the gas block, but that's to be expected.
Next issue I noticed on last round, the bolt tends to pass over the round. Is my bolt cycling too fast?
Next, on last round, the bolt locks open, but removing the magazine releases the bolt. Im assuming the bolt isn't engaging fully? I have a feeling it's mostly related to the buffer spring?
Next issue, I noticed that the muzzle device is not centered in the middle of the free float. In fact, the bottom of the muzzle device is about a few sheets of paper away from making contact with the free float. Doesn't make contact now, but once I add a suppressor [eventually] I assume it will. Did I mess up the install of the barrel nut? Idk how I could have.
