Frequently Asked Questions
Will the AD-AEMS mount fit my specific rifle's rail if it's slightly out of spec?
Yes. American Defense Mfg.'s Patented QD Auto Lock Lever system is specifically engineered to accommodate both in-spec and out-of-spec Picatinny rail systems. The superior clamping surface maximizes rail engagement across a range of tolerances, so you get a secure, wobble-free lock even on rails that deviate slightly from MIL-STD-1913 specifications.
Does this mount provide true co-witness with standard AR-15 iron sights?
Yes. The AD-AEMS QR mount is designed to place the Holosun AEMS at an absolute co-witness height, meaning your standard A2 front sight post and rear iron sights will align directly through the AEMS's window. This gives you a seamless transition to backup iron sights (BUIS) if your optic ever fails in the field.
How reliable is the return-to-zero after removing and reattaching the optic?
American Defense Mfg. mounts are renowned in the industry for their return-to-zero (RTZ) consistency. The QD Auto Lock Lever creates repeatable, positive engagement with the rail every time it is reattached, meaning your Holosun AEMS should return to your established zero without requiring re-zeroing. For mission-critical use, a quick confirmation shot after reattachment is always a best practice.
