Sam from American Defense Manufacturing gave us a booth tour — video above — of some new products at SHOT Show 2015. I’ve played with a lot of ambi AR-15 lowers in the past few months, but there are only a couple out there that actually have a bolt catch on the right side. Bolt release, sure, but not bolt catch. The ADM piece serves both functions, and it even does it more easily and smoothly than any other I’ve tinkered with in the recent past. ADM is likely best known for optics mounts, so this foray into matched billet uppers and lowers is a big step that it looks like they’re taking seriously. Sam showed us a new optics mount for small red dots like the RMR as well. . .
Push down to release the bolt. This was smooth and easy to do.
Push up to lock the bolt back manually.
30 or 45 degree offset sight mounts for left or right sides. ADM makes mounts for most popular, small reflex sights such as the RMR, DeltaPoint, FastFire, etc…
