Re: opinions ought on ADM (American Defense Manu. ring
This exact topic (on most sites) ends up as a brand-name bitch fest between the loyal customers...
I can say I own both LaRue and ADM gear, and find both of them to be excellent...
I currently run (as far as ADM) a Recon 30mm QD Scope Mount, a Cantilever Aimpoint Mount, a Surefire QD Mount (for an M951), and 2 or 3 of the TD QD VFG's (Which use ADM QD Mounts, BTW, in case you weren't aware).
I also own an LT-104 Scope Mount, an LT BUIS and have owned an LT Aimpoint Mount in the past. I've shot or handled pretty much every mount (I Think) that LaRue has put out in recent years.
I've never been less than 110% satisfied with any of them.
Mark LaRue turns out great shit - no doubt about that. As a fellow Texan, I try to take his tantrums with a grain of salt and just chalk the eccentricities up to ego. It IS a justified ego, but I will admit I prefer the "quiet professional" personna that several in the industry adhere to. That being said, he is a lightning rod and has successfully defended his products on several fronts. Few have anything bad to say about his gear that doesn't stem from personal discontent.
But, ADM catches a lot of flack from the LT Fan Base - and if not for the negativity that comes from that arena, I feel that they would be held in far higher esteem...
All that being said (since the OP is asking specifically for thoughts on the ADM mounts).
I've found the Recon Mount I own to be exceptional. Return to Zero is positive after several dozen dismounts (both for weapons maintenance, and probably a dozen or so in the first few range sessions to build my confidence in the mounting system - it was the first ADM I owned and I wanted to see for myself). I run a Falcon 4-14 FFP on an 18" HB Varminter/SPR type rifle in this mount. I can say from personal experience that a 10 shot group at 300 followed by a dismount and a second 10-shot group will overlay one another in such a manner that strings could not be distinguished except by individually logging each shot. I have a photo of these strings on my old phone and will see if I can dig it out.
The same holds for my Aimpoint, although I don't shoot it in a manner to distinguish sub-MOA shifts in zero. I can say that I've removed the mount more times than I've kept track of, yet I've never re-zeroed the optic since the initial install - maybe 2K rounds ago.
As far as robustness of the mount, I'd guess that the average VFG takes far more pounding than the average optic, and a single ADM QD mount is used on the most popular QD VFG on the market (versus the double QD's used on optic mounts).
The two brands use drastically different styles of mounting mechanisms, and both have detractors. I do tend to believe that the LT style mount should be stronger - but am not sure that at the energy levels required to damage either style of mechanism that the item being mounted would not be destroyed long before the mount.
Don't want to come across as an ADM ass-kisser. But, I've found their gear to be perfectly serviceable, and will continue to consider them a viable option for mounts that meet my needs...
DISCLAIMER: I do not work for, know, have any idea what they look like, or expect to ever meet anyone who works for either LaRue or ADM. I am strictly a one-way cash-flow proposition for them (they get my money from time to time, that's the extent of my involvement with them)...
