Can this go on a standard AR lower?
Rick V on Apr 26, 2019
BEST ANSWER: Yeah, that's the point. Swap out your existing upper and install this on your registered SBR or pistol lower. Grab some BDT .22LR magazines.

Is this a different model from the Gen2 8.5" accurized model that you have sold?
Fred on May 8, 2019
BEST ANSWER: I only shot 10 rounds to adjust the scope at 25 yards. On the last four rounds, 3 grouped at 1/2". I then made a 1/4" diameter dot on the cardboard box. Fired the last round at that dot - bullet hit the dot dead center. Note that I was shooting off a single sandbag which was on a plastic picnic table. Also I had to use a lower power on the scope as the focus only goes down to 50 yards, so it was too blurry at higher power. No way I could tell if the size of that 1/2" group was the gun, the scope, or me. Until I shoot it bit more, that's as good as can explain. I wanted to get my review up ASAP, as I was taking a chance ordering this a week ago with no reviews posted at all. That was the reason for my "rushed" review.
Does this have enough clearance to thread on a suppressor (ie Sparrow .22) or other?
G B on Apr 26, 2019
BEST ANSWER: Barrel extends past the end of the rail so no clearance needed.
Is this compatible with Smith and wesson mp 15-22 magazines? What about with the boonie packer redi mag adapter?
Shane P on May 8, 2019
BEST ANSWER: Yes you can just use the mags or with the boonie packer adapter
Is the bolt carrier goup ccmg or a copy?
steve t on May 8, 2019
BEST ANSWER: There are no markings on the bolt carrier to indicate manufacturer. It appears to be well made,
When in stock will these be?

Will this work with s&w 22 mags?
David O on May 8, 2019
Can anyone verify if a binary trigger will work with this upper?
Matthew M on May 13, 2019
BEST ANSWER: Yes, it runs with a Franklin Armory binary trigger just fine. I was shooting suppressed with sub-sonic ammo, so it's sure to work with high velocity ammo too.
Does this have last round bolt hold open?
Eddie B on Apr 30, 2019
BEST ANSWER: use boone and packer better mag adaptor and s&w 15-22 mags works great
Will this interchange on the S&W MP 15-22?
Craig R on May 14, 2019
Is this compatible with Smith and Wesson MP15-22 lower receiver?
Parchit on May 13, 2019

BEST ANSWER: You'll need magazines and 22 ammo and the sighting device of your choice.

So much fun to shoot!!
LOVE it!!! I took it to the range this weekend, as is, and it went to town with Federal bulk and some CCI mini mags. Everybody at the range was asking me about it. I can't wait to shoot it in my first rimfire steel competition next week.
Shoots great with Black Dog magazines

Disappointing...par for the course
Many failures to feed, stove pipes on every magazine. 325 rounds in using cci standard velocity. Maybe it has a 1911 type break in round count of at least 500rds? Or maybe psa is back to their old QC values?

Going to take it to the range one more time to see if it is just a round count issue. If not I’ll be sending another psa product back for repair.

Great pistol upper for hours of fun!
I really love this pistol upper. It was picky with some cheaper LR ammunition, but CCI Mini Mag and Stinger work very well! I would like to purchase the rifle upper next. The Black Dog magazines work very well with this upper.

Nice 22LR upper!
This upper fits perfectly on the PSA lower, and functions flawlessly. It is very accurate, and is capable of very tight groups. Uses 25 round black dog mags.

Great upper!
Great upper that runs without any issues. Have run several different rounds through it with great success. I only wish it had a lighter profile barrel.

Excellent 22lr upper.
I looked at the CMMG and Nordic uppers, but couldn’t justify the price for a plunger. I’ve had this Palmetto 22lr upper for over a month now. Zero miss fires of any kind, with 500 rounds thru it. Works amazing with a suppressor. Excellent job Palmetto.
