Haus Manufacturing HK416A5\A7 upper and Brownells HK416 bolt carrier fitment issues

My first video concerning parts for chemically powered mass accelerators!

Sorry for the bad lighting and pauses, this was completely unprepped as I just got the part today.

After looking at the video I realized that it wasn't so much the smaller tip on the Brownell's pin as it was the length of the thin section that allows it to work while keeping regular pins from being able to function. I don't know if HK pins will work in the Brownell's carrier.

After milling down the forward skis on the bolt carrier it fit fine.
