    M16A4 Clone

    Picked up an A2 FSB for a M16A4 build that I was putting together. Pins worked out great. BCM always delivers.

    Good part, fantastic customer service.

    I was rebuilding an A2 style rifle and had lost some of the pieces, so I needed this and one or two other pieces. These BCM components worked perfectly and when I said in the order notes that I needed a gas tube roll pin but could not find one by itself on the website, they threw it in the order for free. Fantastic customer service; the real deal. Very grateful.

    Good product, great service

    Bought these because I was rebuilding an A2 rifle and was missing these pins and a couple other pieces. Shipped quickly, worked perfectly, and Bravo Company threw in gratis another little piece I was having trouble finding. Great products and superb customer service.

    A2 gas block pins.

    Ah, the pick of these pins was next to the gas block I ordered. I was not paying attention and ordered by mistake thinking it was the pin for the gas block. The pick was next to the low profile gas block I ordered. I did not pay close enough attention. Not worth the trouble to send back. I'm sure they will be fine if I ever do a retro build.
