Does the last round bolt hold open work if using the KAK mag well insert (designed for standard ar LRBHO to remain functional)?
Brad H on May 7, 2018
BEST ANSWER: Brad,
I mounted my 4" upper on a PSA 9mm dedicated lower with LRBHO. If you look at the upper listing I think they are only compatible with the PSA 9mm lowers. Do not think it will work on a AR lower with adapter block.
Are the bolts ramped?
M Y on Apr 18, 2018
BEST ANSWER: Yes. It is the PSA hybrid ramped bolt.

Cheap and good
Runs good on Russkie steel cases on a lower with a cheap plastic Colt adapter and an Echo trigger. My cheap mags are the only issue I have had. I run it hard and put it up wet and it keeps on going. Get it.

Very impressed, with my new PSA 4” 9mm upper. You don’t need to drain the bank to build a sweet AR9.
I would absolutely recommend this complete upper. I’m always on a tight budget. This complete upper is solid, reliable and looks and functions great for the money.
The PSA 4” 9 mm complete upper was perfect for my pistol project.
I would barely call if a blemished upper. Very happy

Exactly as ordered and a prompt delivery. I am very pleased with the product. This is not my first PSA order and it certainly will not be my last.
So far, the product has looked great in my safe. I have yet to complete the build. However, the upper system itself is in perfect condition. Despite being a "blem" model, there is no visible blemish that I can find and I have OCD when it comes to my guns. Highly recommended*

Top Quality Upper
If your looking for a lot with less money to spend you won't be disappointed with this upper. As usual Palmetto State Arms Quality and workmanship comes through with flying colors. I have had zero issues with this upper. No malfunctions of any kind and fit, finish, and workmanship are superior for the money. Get one while you can.

9mm hybrid pistol upper
This makes my second pistol upper from PSA and this one delivers once again. My first was a 10' but this little shorty rocks! I think it's a perfect size for the AR pistol platform. I will order another if they ever show up in inventory again.

Lots of fun in a small package
I put this on to a PSA 5.56 lower with a Torkmag glock magazine block and hiper fire trigger. This is one compact package that runs great! I just wish the hiper fire trigger worked in my PSA 9mm carbine.
