I have shot a couple of these guns that had high round counts and they seemed to be very well built. I have a handguard of theirs on a rifle that has been used for duty and its well built. Their hand guards were very popular in the 3 gun circuits a few years back. ADM optic mounts are still used regularly and were one of the OG optic mounting options several years back. Optic mounting is a very flooded market now with lots of quality products and it seems that someone claims to be the new king of the hill every other year or so. If you listen to the primary and secondary modcast, ADM was mentioned in some older episodes. If I recall correctly, ADM was mentioned as a rifle that appears in classes regularly and that they seem to perform very well, I do not recall the episode numbers were it was mentioned (probably an older open mic episode). Also check Sage Dynamic Videos on the net. Aaron does a few ADM reviews and performs a burndown process in his videos.
