Slick and clean appearence, very lightweight; fits aero precision m4e1 upper - V Seven AR-15 Ultra-Light Port Door

I wanted an ejection port door that would compliment the "top-of-the-line" look to my M4E1 upper/Radian AX556 Lower build I'm assembling. I ordered the "Air" version because it was the lightest of the three port door options offered by V Seven, and likely the lightest ejection port door for the AR-15 market as of right now. My setup includes: Aero M4E1 upper, Radian AX556 Lower, BCM BCG. So far I have no issues closing or opening this ejection port with this specific setup.

Aesthetically, I'd argue that V Seven's ejection port doors are the best looking on the AR market. The "Air" version has a smooth satin black finish that, when closed, becomes a focal point of the upper receiver. It perfectly matches the finish of the Aero M4E1 upper receiver. In practical terms, the port door is almost comically light compared to the "standard" ones you'd find in most builds. It's also made of 7075-T6 aluminum; a much better and stronger alternative to 6061-T6.

Aesthetics aside, V Seven's port doors are an excellent component to upgrade for a higher-end or lightweight build. Although they serve the same purposes as any other port door, they, in my opinion, look good enough to justify the price. If you buy this, I highly recommend buying V Seven's "Ultra-Light Port Door Rod (AR-15)", which is an additional $10.
