USNBS AR-9 Billet Upper Receiver for 9mm / .45
Perfect I bought 2 of them. one for a AR9 build and one for a AR45 build. Went together very smooth.
USNBS AR-9 Billet Upper Receiver for 9mm / .45
Works out perfect on a PCC 45ACP pistol
United StatesSolid piece
Excellent option for a pcc build. Enlarged ejection port definitely helps AR9 run more reliably, likely easier to clear malfunctions but I haven’t had one yet with this upper. It may be 6061 but it’s plenty sturdy enough for the task. Just ordered another one. Running mine on a slim cut Colt SMG mag lower.
USNice PCC Receiver
Great receiver for the price, went together with no issues, it was the perfect receiver for my 40cal PCC build
