Default LPK Installation

Well I received my LPK from Palmetto State Armory and so far so good, I only have two hang ups, one which is keeping me from finishing. I am unable to get the roll pin to go into the rear end of the trigger guard, the one closest to the grip, and i also am unable to get the trigger pin to go through the entire trigger, even when it is out of the lower. It looks like the disconnector isnt allowing it all the way through. Any help with these problems would be greatly appreciated!

You could hand turn a proper sized drill bit inside the trigger and disconnector hols to remove flash, etc. Be very careful with the trigger guard ears, don't whack on the roll pin with the bottom ear unsupported. Easy does it.

Awesome! I tried the drill bit in the trigger guard and it worked like a charm. I haven't had a chance to try it on the disconnector yet

Make sure teh disconnector spring is right side up. The fat end goes down into teh tail of the trigger. If you have the fat side up it can keep the disconnector from sitting all teh way down in the trigger.

Ill have to double check that. I think the fat side is up. I didn't know it mattered. Learn something new everyday

You'll feel the disconnector spring "snap" when it goes into place.

I was able to get it as much together as I can for now (I still need a buffer tube and stock assembly) but here she is so far! I think I am going to top her with a 300blk upper since I have a bunch of .223 casings and .30cal bullets for when I reloaded my .308. What do you all think? Also what would a good barrel length be for the blackout? I would like to make it an SBR with a can but alas I am not able to since I am not yet 21
