Works as advertised


Easy to adjust and mount. Ring holds the optic securely. Swings out of the way easily, however, would like to see an adjustment to tighten up the swing tension a bit..feels somewhat loose. For the price, this is an excellent product

Great swing Mount


Excellent works perfectly

Solid swing mount


First, shipping what super fast and I'm from Hawaii! This ADM mount has a solid feel with no wobble. Lines up perfect and clears my Magpul MBUS Gen II just fine. Thanks PA!



Great Mount! Quality craftsmanship and build quality worth every penny!

Nice and functional mount


I bought this to go with my Lucid HD7 and Lucid 2-5x magnifier on a PWS MK114. Everything lines up perfectly and with the Magpul backup sights, when I swing the magnifier out of the way I can co-witness in the lower 1/3 of field of view. Pretty happy with the mount so far but I have not used it at the range yet. I would give it 5 stars but there seems to be a small amount of vertical play that can be induced with very slight pressure on the magnifier. At this point I assume that this will not effect anything since the red dot is solid and the magnifier having a small amount of movement should not change point of aim. If this is true then 5 stars is appropriate but for now since I am not sure I will give 4 stars.Purchase from Primary Arms was quick and flawless, which is a lot to say considering the huge amount of orders the industry is going through right now. Price was right as well, thanks!

Good FTS Mount


I couldn't bring myself to buy a $260 Samson, so I tried this one. It doesn't have the Samson/EOTech button, but it operates smoothly and solidly. I had an issue with the springs in the picatinny rail. PA offered to give me an RMS and American Defense offered to send me replacement springs. Great response form both companies. I'm sure the mount is fine, but one of the springs launched into the air, so I took American Defense up on their offer and they are sending me a few springs free of charge.

American Defense Magnifier Swing Off Mount


I got exactly what was promised which can't be said by everyone these days. I had some questions which were professionally addressed, the shipping time was actually shorter than i expected and the product was just as it was billed and exactly what i needed. I will definately be ordering with Primary Arms again in the future.

Awesome mount


I got this mount as part of a package deal with my magnifier and it is great. Awesome piece of equipment and a great addition to my AR. Buy with confidence on a great piece of American engineering.



I looked and looked for a mount that would be tall enough for my Eotech 517, since it is 7mm higher than a standard height. This mount is only .018 shorter then the center of the Eotech. I had watched a youtube video of someone demoing at swing mount style and realized that was the one for me. Even though I have played with one in a store. (Vortex VMX3-SM-01) I like the fact that when its not in use it actually lowers the magnifier out of the way so you can acquire targets better then a flip mount. The mount is able to swing left or right. But the mounting plat is not reversible.PRIMARY ARMS has excellent customer service, I bought the magnifier first and a few days later decided on the AD-SM-01, I emailed customer service, and they allowed me to purchase the mount at the same price as if I was purchasing it as the bundle. Will buy from the again, my only gripe is the stuff I want seems to never be in stock. Thank you, Daniel

Better and better


I love the action of these mounts, I have been buying them for a while now. This last shipment shows me that they are continuing to try to improve them; the finish is smoother, with a better anodized coating, and the action is smoother than a previous iteration. Ans as always PA delivered unbelievably quick.
