I purchased this upper receiver just to check out the BCM hype without breaking the bank. It is advertised as having a tighter barrel extension fit, sometimes requiring heat to fit. With the barrel I had on hand, the fit was more snug but the barrel slipped in without trouble. The everything about the receiver seems to be fine, the only blemish I noticed was the smudgy forge mark pictured below. Looking to get rid of it because my OCD won't let me be.
$55 - Comes with a dust cover and forward assist.
