Upper:  Precision machined from forged 7075-T6 aluminum, then Black anodize hard-coated to MIL-8625 Type 3 class 2.   

Bolt Carrier Group:  9310 steel bolt assembly, nitride treated for durability.  8620 carrier, nitride treated, with a nitride treated gas key properly staked with grade 8 fasteners.  Charging handle is also included.

The Gen2 PA10 receivers are functionally compatible with the Gen1 upper receivers, however, we recommend matching Gen2 lowers to Gen2 uppers for best appearance.  There are external cosmetic differences when mixing Gen1 and Gen2 upper and lower receivers that some may not find appealing.  Gen1 lowers will be available in the future for those who want a cosmetic match.

No warning about "All NFA Rules Apply" here, I see? Just letting customers think they can pin this to their PSA Gen 2 rifle lower and be okay... While they're creating an illegal Short Barreled Rifle by doing so...

BEST ANSWER: When you buy a car, do they tell you how fast you can go or which side of the road to drive on? It’s YOUR responsibility to know the laws. Quit trying to pass the buck.

This upper is great. Very reliable and shoots really accurate for such a small gun. Haven’t ran it past 300 yards but up to 300 it shoots really good.

She’s getting 5 stars!!! Because she has performed flawlessly so far after a few hundred rounds. Not one hiccup! AND, even at 12.5”, she’s still deadly accurate with tight groups around 1/4”-1/2” at 50yards. I know that’s not very far, but the prism 2.5 power scope I put on her zeros at 50 and that’s all I’ve taken her to so far. I’ll post more results later once I’ve taken her to 100 yards and obviously discovered the round she likes. Btw, for now I’ve only fired LC 7.62 ball and a handful of LC 7.62 LR118 (older 168 grain). She preferred the ball rounds over the LR118s. With that twist rate you’d think the heavier grain match rounds would perform better. Still have some more testing, I’ll try the newer heavier LR118s if I can get my hands on some. Would like to try this baby out during the alternative portion of MO deer season. But won’t until I find that sweet spot round for her!!

I’m writing this review just of the fit and finish. I have not had a chance to fire it but will update on how that goes. At first glance this looks very nice at the unboxing nothing looked out of place. Once it tried to match it to my lower is where I became disappointed.

I’m not a first timer and I have build several AR platform rifles and guided many coworkers with theirs. I usually only build on high end billet sets with top of the line parts and customize them. This one is different, I wanted a cheap build that shoots well.

If I didn’t mind taking a dermal to the upper I would have returned it and gave a1 star.

That said let me start with he first of 4 issues.
1. The front disconnect lug was to large and would bind if I tried to open it until I removed a good amount of material from the curved part of the front lug.

2. I use AR10 lower parts kits not not ar15 parts. So when I went to close the upper to the lower the bolt catch was hitting the upper, due to the notch was not milled out high enough and if I closed the upper to the lower it in gauged the bolt catch behind the bolt. This would not allow me to cycle the action to preform a function check.

3. The forward assist is so far back that it will only forward the bolt about a 1/4” from locking. The bolt ether needs 3 more teeth cut into the side or the assist needs moved forwards. I’m guessing the bolt is the issue since I’m guessing PSA is not casting their own uppers.

4. The rear disconnect lug is good for fit. I did notice while in figuring out the first 3 issues I noticed the hole was started oval then corrected. I would guess it was from a over used milling tool that should have been replaced sooner.

I know that PSA does make most parts in house and I have had many friend buy their ar15 complete kits

All the issue I have I no problem addressing in my shop. The one issue that will make me slam this will be if it doesn’t zero. If it doesn’t fit and you don’t feel like working on them like I do be ready to return.

I will let you know if it doesn’t zero.

Excellent workmanship, fit, finish and function. Very well balanced gas system. Would have liked well-placed QD on handguard, but where is "well placed?" right? All around awesome product.
