The American Defense quick detach T1 micro mount is an excellent option for all T1 compatible optics including the Primary Arms MD-ADS and MD-RB-AD. Like all American Defense mounts is precision machined from durable 6061-T6 aluminum with a hardcoat anodized finish for long service life.

This mount is designed to place the standard AR-15 iron sights in the lower 1/3 of the optic's window for an unobstructed view of the target.

Featuring ADM's QD Auto Lock Lever system, the AD-T1 can be fully adjusted without tools to accommodate most Picatinny rail systems. This glove friendly locking system ensures the mount will not move until you need to remove it, and provides exceptional return to zero with mounted optics. It is also fully covered by American Defense's lifetime warranty.

Awesome Mount!


Bought a micro red dot and was originally going to mount it on a very inexpensive mount, but after exchanging emails with PA decided to get this AD. Sure glad I did as this mount is super quality, easy to use and Made in the USA. As usual great customer service and fast shipping. Thanks PA.*EditJust put another 100rds through my Colt M4 and this time I removed the mount a couple times to see if it would hold zero. It sure did. This is one great mount!

Great Mount for the price!


Have been abusing the mount and putting it through some rough conditions in the last few weeks and no issues except the mount loosening a little. This was due to the fact that I had not used any loc-tite. Since the loctite no issues. Very pleased with my purchase!

Nice mount


I already own an LT mount for my Aimpoint. I wanted the same type of detach feature for my Vortex SPARC. I bought the ADM as a lower cost alternative. The ADM is a nicely machined mount. I would not hesitate to buy another. Primary Arms ships quickly and has good prices.

Great quality, but too high to cowitness


I bought this mount along with my Holosun HS403C (a great alternative to an Aimpoint) and I love the fit and finish of this mount. Extremely high quality and the Quick Detach is awesome. The only downside is I bought this over the absolute because a lower 1/3 cowitness sounded more appealing, but this mount is so high that I cannot see my sights at all through the red dot. Maybe it's just the sights I'm running (Magpul MBUS pros), either way this mount is solid.

Small, well-designed mount


I like the mount because it is made to be as slim and light as possible. There is a locking tab on the quick-release lever at the base - this prevents the lever from from being bumped and accidentally released. Very high quality fit and finish.

top notch customer service


I purchased a micro dot and had a problem with a mount I already had. I called and told them what happened and they sold me a new mount for the bundle price. Saved me $20. They I recieved the mount it was not the one I wanted so they shipped it back on them and sent me the one I was looking for. They didnt charge me for any of the returns. I will definitely tell people about their customer service. Also the dot looks well made. I sold my Aimpoint T-1 and wanted to replace. I am happy with the Primary arms dot.

Made it right, right away


I received a manufacturer's sealed box labeled 'AD-T1-11' within a few days of placing my order. Problem was that the box contained a T1-10. So I emailed Primary Arms asking how to resolve the mistake.PA responded that they had forwarded my email to AD and to let them know if I needed any further help. Warning bells rang because it took 4 months and many calls to resolve a similar situation with a Florida company (spider logo). I waited, never heard from AD, and gave PA a call. When PA learned that AD had not contacted me they kept me on the phone while they opened a second T1-11 box, verified its contents, and told me they would ship it at their cost with a pre-paid mailer for the return. I was impressed, that is great customer service.I like the T1-11. It is light and compact. While not quite the level of Bobro, their QD clamp is very good. FWIW, I chose this unit over the Bobro mount specifically because of the smaller overall size and lighter weight.

Excellent upgrade mount


I've had my MD08 microdot for a little over a year now. Initially I cheaped out and just went with the included PA basic quick detach AR riser that came with the dot. It worked for a while but eventually the cheap roll pin started to work loose and the dot started to wander zero. Finally broke down and purchased this mount and extremely pleased. I wish I had ponied up initially and gotten this better mount initially.

Works great!


Mount fit and finish is great. Had no issues mounting red dot and then to rifle. Zeroed with only 6 rounds, can't ask for more. Mount arrived in record time from Primary Arms. Always a pleasure doing business with these folks. Great staff and awesome customer service.
