First few hundred rounds have gone through flawlessly, can’t think of any complaints! It fit perfectly onto my PSA lower and looks great.

Great light weight carbine package with the MOE handguard. Nice nitride finish on my particular upper. No extensive testing yet but seems good so far. Always been pretty happy with my PSA purchases.

It’s awesome, fast shipping.
This my first AR, am no expert in regards to this. Paired with PSA classic lower and it fits perfectly, out in the range it shoots great, with no mulfunction or whatsoever. I highly recommend it for those who just started like me or about to start building their first AR.

It arrived on time and well packaged. This complete upper fit my Bushmaster XM15 lower better than its original. No play or rattle. Bolt was MPI but not HPT but it wasn’t advertised so no heart burn. I couldn’t reinstall the firing pin retaining pin. I’ll have to get a pick set to try to get it back in. I’ve never had this issue with any of my other ARs.

Great Upper
I’ve purchased several items from PSA over the years. The fit and finish on this upper was proper in all aspects. Will by again without hesitation. PSA has always provided me with excellent service and competitive pricing.

Good quality complete upper.
Very satisfied with this upper assembly. Good finish and it matched mechanically perfect with Anderson stripped lower. Test fired using XM193 ammo with 100% functionality. In my opinion, for the price, there is absolutely nothing comparable from any other dealer.

I would definitely recommend this upper to others.
