Will this upper work with the PSA PX9 Blackhawk Classic Glock lower ?
Darryl W on May 3, 2018
BEST ANSWER: Yes. The PSA upper has a hybrid BCG that works with the PSA Lowers. The only trouble I had with mine was the hammer pin walking out sideways. I replaced it with a non-walking pin that I bought from Midway USA. Otherwise, it would double or go into a full-auto burst. Good luck with yours. You should enjoy it.
Will this lower work with any other dedicated 9mm lower or ONLY the PSA lower?

BEST ANSWER: I think it would work with any 9mm AR-15 lower.
Think about it. The lower dimensions are standard to annoy AR-15, I measured it and it matches perfectly. PSA claims it will work with either their Glock lower or the other they haven’t had available for ages. So, I’d say, if you are going for a non PSA Glock lower, you’re good. Remember to get the heavier buffer for your build because the regular 5.6Oz buffer won’t work. Mine didn’t. Had to go to 8Oz but works seamlessly...
Good luck and have fun building your gun!
Will this attach to a Colt 9MM lower?

Excellent Value and Very Accurate
Mainly use for Carbine Pistol Caliber competitions at my club. Shot 5” plates at 15 yards in 2.2 seconds my first try! My setup is PSA AR15 lower with KAK 9mm insert POF 3.5lb straight trigger red dot colt magazines KAK 9mm 7.5oz buffer and 9mm spring. Upper is tight on lower no play. No stove pipes and no failures to feed. Very tight groups at 25yds 50yds and 100yds. It is a fun to shot!

Great upper for 9mm enthusiast
Purchased this upper along with the designated lower. Excellent fit and finish. So tight I use a rubber mallet to seat the pins. They will loosen over time so this not an issue. Operations and reliability are excellent. We have put over 500 rounds through it so far no issues at all. Operates flawlessly looks great. Two points need to be explained and It's my fault I apparently can't read. The description clearly states there is no "last round bolt stays open" feature and the threaded barrel is threaded to 1/2x36. Standard however is 1/2x28. You will need to purchase a 1/2x36 to 1/2x28 adapter if you plan on using a surpressor. PSA has been very helpful in helping me find the proper adapter.
If you are interested in a vendor who sells nothing but quality products at incredibly low prices don't overlook PSA. I can testify that their prices on firearms ammunition and AR builds are the lowest I have found. Their customer service is exceptional shipping is quick and if you have a question their expertise is on target.

Grab this upper when it's im stock!!!!
I was lucky to get this upper while it was in stock. This upper does not stay in stock for very long. Seems like there gone with in a hour's time. Might as well pay the few bucks more. You get the handle and BCG.
