Tom smithy

by Tom, Verified Owner from HI, United States Written on May 4, 2025
Amazing fit and finish and high-quality American made product. Just not what I required for my current set up as it is not a 1.93 height. But will definitely be holding onto it for a future build. I would highly recommend it if this is what you are looking for. As the ACSS reticle on this specific holosun is a platform that there are not too many mounts out there
Pros:
  • Tough combat ready optic mount
Cons:
  • Not a 1.93 height
  • Are not able to use back up iron sites due to the location of how the amount is set up
Best Used for:
  • A tough and rugged build for the range
Would recommend: Yes

excellent!

I use Midwest industry and Larue mount but mostly choose American Defense Manufacturing. My wife needed a mount for one of her new shotguns. Quick detach is the way to go. This was a good price as is exactly what she needed for her red dot. Like many, she has become concerned with the state of this nation and ridiculous crime that comes with a failing government. She struggles with accuracy from a sidearm/pistol but not rifles where she is far more stable. She has wanted her own tricked out shotgun. After buying a panzer m4 she wanted to upgrade to a Beretta a300 she saw at Bass when I was looking a pelican rifle case. What’s better than American Defense Manufacturing? A super hot wife that enjoys firearms as much as me.

Very Solid

by Wizgoober, Verified Owner from MT, United States Written on July 6, 2024
Well constructed & finished. Bought this for a HS510 that got mounted to a Beretta 1301. Wished it was a little lower to co-witness with the factory sights, but…physics. Overall, I’m impressed with the fit & finish of the mount & it’s very solid on the shotgun. I’ve got a 100rds thru the combo with no issues. I’ve not taken it off to check the zero after re-mounting, but am confident it would be just fine. Great product & (as always) great service/support from optics planet.

Best low mounts

by John Dorr, Verified Owner from WA, United States Written on June 16, 2024
These still add a little height and generally can't be used with sights. The base is also slightly longer than the small optic.
Pros:
  • Great quality and function
Cons:
  • Extra cost but worth the price
Best Used for:
  • holosun
  • Holosun SCRS
Would recommend: Yes
