For a long time, I've run a TA11 in an ARMS #19S mount and I've been quite happy with it. The ARMS #19S returns to zero reliably and does everything I need it to do. Recently I had to send off the upper to have someone else work on it, as a result I would need to rezero the ACOG anyway and this got me to thinking whether I shouldn't give the Larue mount a try.
I'd fired a few guns using Larue mounts and they appeared to be quality mounts that returned to zero perfectly. I also like the idea of adjustable tension since one thing I had noticed with my ARMS #19S is that it was becoming looser over time - it still mounted firmly and held zero but it no longer required near as much force to flip the throw lever and that concerned me. At the same time, I had promised myself that as long as it was holding zero I wouldn't swap out a perfectly good mount that held zero for another mount that did the same thing just because it was the latest & greatest.
Finally I decided to give it a try... and I have to say, I am impressed so far. The Larue mount not only includes a top quality mount; but comes with all the tools you will ever need to use it, including an allen wrench for the mount screws, two mount screws, a tiny tube of loctite, and a small wrench to adjust the levers.
Considering the ARMS #19S didn't even come with any screws to mount the ACOG to the mount, I have to say I am impressed with the level of detail Larue put into their product. All in all, I didn't need the Larue mount; but it is a very nice product and I am not disappointed with the purchase. I plan to give it some serious use and fully expect to be placing the ARMS #19S on the EE soon,
