Madhouse Posted May 5, 2013 Report Share Posted May 5, 2013 Started with an ATI stripped lower, added a Palmetto State lpk today. Not real sure yet where im going with this, probably just a functional tactical unit. Quote Link to comment Share on other sites More sharing options...

blue109 Posted May 6, 2013 Report Share Posted May 6, 2013 i have 3 lowers built with PSA LPKs here right now. selectors are nice and tight in all of them. Quote Link to comment Share on other sites More sharing options...
Madhouse Posted May 6, 2013 Author Report Share Posted May 6, 2013 Hey unforgiven, mine is like blue109 described. Tight, transitions well between fire and safe. Quote Link to comment Share on other sites More sharing options...
Madhouse Posted May 6, 2013 Author Report Share Posted May 6, 2013 I did have a little trouble getting the bolt release catch to work well. After I tapped in the roll pin it seemed tight, the spring wouldn't reset it, but I dropped some Break Free in there and it loosened up, now it snaps back into place. If you're having trouble with the selector being loose, I wonder if their springs are up to snuff... Quote Link to comment Share on other sites More sharing options...
unforgiven Posted May 6, 2013 Report Share Posted May 6, 2013 Rob suggested the channel might be to deep on selector but if no one else is having a problem <dontknow> .That was my first lower build.Went through the parts process of elimination on what went where.About the only springs that looked similar in lenght were takedown/pivot and selector.Use same lenght springs for takedown/pivot and other for selector.I got BAD selectors to replace just wondering for myself if I fukedup or what. <dontknow> Quote Link to comment Share on other sites More sharing options...
Dane Armory Posted May 6, 2013 Report Share Posted May 6, 2013 I assembled an ar15 lower acouple weeks ago and used a longer selector spring to make the selector work properly. If it is too tight you could cut a couple of coils off of the standard lenght selector spring. Or if it rotating freely find a longer spring at a hardware store and use that one.

Madhouse Posted May 8, 2013 Author Report Share Posted May 8, 2013 Nice! The addiction begins!! Jon Ha, yeah, I've got another PSA lpk with the QMS trigger. I'll get another lower at the next show and start a different build then. Now, on to uppers. I'd really like to put one together from pieces, just to say I did, and for the knowledge.

Goofball310 Posted May 8, 2013 Report Share Posted May 8, 2013 Build sounds like it is coming along really well. Any special plans for the barrel and upper receiver? FYi, If you plan on using a FSB then you need a barrel that is designed for it. Quote Link to comment Share on other sites More sharing options...
unforgiven Posted May 8, 2013 Report Share Posted May 8, 2013 For $65.00 the ACT trigger has a good feel.Just sayin.PSA had it in one of there LPK. Quote Link to comment Share on other sites More sharing options...
98Z5V Posted May 10, 2013 Report Share Posted May 10, 2013 For the mag catch on these, make sure you guys are screwing the button down until it's flush with the end of the screw. It makes a difference in operation, if it's not on that far. <thumbsup> Quote Link to comment Share on other sites More sharing options...
Madhouse Posted May 26, 2013 Author Report Share Posted May 26, 2013 Any special plans for the barrel and upper receiver? Nope, no real direction on this one just yet. I was actually thinking of just getting a complete upper kit from sarco for 450 just so I can assemble it. For grins. Quote Link to comment Share on other sites More sharing options...
jrtmasp Posted May 27, 2013 Report Share Posted May 27, 2013 (edited) I recently bought a RRA LPK at a really good price and will compliment it with a Geiselle SSA-E down the road, using the extra parts as backups. Tom recommended the Armalite LPK with match trigger awhile ago and I think I'll be giving that a shot on my SBR build next year. I've never bought a PSA LPK but have mostly heard good things.
