Aero sells these as a full assembly with rod, spring, and c-clip preinstalled which saves the worst part of changing a dust cover. Black anodizing matches my Aero upper. Spring pop is positive when the BCG cycles. Solid budget option.
assembly comes with the door, spring, and pin. snaps shut with positive tension when you charge the rifle. roll pin install is the only fiddly part, took about 2 min with a punch set
Aeros ejection port cover comes with the rod, spring, and c clip preinstalled which is the only way to buy these. Spring pops the door open positively when the bolt cycles. Black anodize matches Aero uppers exactly. Easy 5 minute install with the right punch.
Aero Precision ejection port cover assembly is well made with the rod, spring, and c-clip preinstalled. Saves the worst install task. Spring snaps the door open positively on bolt cycling. Black anodize matches Aero uppers exactly.
works as expected. price is a little steep for what it is
