BCM upper receiver with BCM forward assist and ejection port door. Assembled by me. This is not one of the new ‘BCM4’ uppers. It is marked ‘M4’ above the gas tube hole. This receiver has been used on an upper build and has seen about 200 rounds - dry film lube is fully intact. The only cosmetic blemish aside from signs of normal use is near the forward assist roll pin where my punch slipped :nono: Threads are in perfect shape as well as the indexing pin notch.
$60 shipped. Discreet paypal gift preferred.
Threads look worn because of the leftover moly grease reflecting light but the anodizing is fully intact.
