This Bear Creek Arsenal complete upper half, like all of Bear Creek's products, is fully designed and made in the United States of America. This allows Bear Creek to put every upper through numerous QA/QC checks, including test firing prior to approval and shipment. Thanks to this rigorous testing, this complete rifle is backed by Bear Creek Arsenal's limited lifetime warranty!

This 16" upper is chambered for 300 BLK and features Bear Creek's exceptional 41V50 Chrome Moly Vanadium steel barrel with a reliable carbine gas system. The 1:8 twist is ideal for the full range of 300 BLK loadings. Both the barrel and M16-cut bolt carrier group have a durable parkerized finish. The high quality bolt carrier group has been high-pressure tested and magnetic particle inspected so you can be 100% assured of no material defects.

This complete AR-15 upper receiver has been topped off with a free float M-LOK handguard, improving airflow and allowing for improved accuracy.

BCA upper review


Thought I'd write a review as no one else has on this upper. Finish was nice, the crush washer was a pain to remove for mounting a different flash hider, mine came with a full picatinny at 12 O'colck instead of the one pictured.
<br>Shooting: functioned perfect with my supersonic handloads with and without suppressor. Accuracy was great with my best 5 shot group printing 3/4" at 100 yards off a rest with a 6x Kahles scope. These were test loads for this gun. One round of Hornady 194gr subsonic was fired at the end of my string and it did not cycle the action completely.
<br>I'd say for the money this upper was well worth it and I'd buy it again.
