I’ve been all over the place with mounts. I bought a LaRue LT129 for my Comp ML2, which was the absolute nuts in terms of quality:
I loved the way the mount’s base ended dead, at precisely the front edge of the receiver and the Torx fittings were a great touch. However, I soon realised that I didn’t get on with lower 1/3 co-witness.
Having also bought this beautiful Daniel Defense mount for my forthcoming H1 – which was also 1/3 co-witness – I had a bit of a quandary.
I couldn’t find many absolute co-witness mounts for the H1, but the American Defense AD-T1-10 cropped up at Midway UK. Since ADM’s QD mech is well regarded (my mate Jay is a big fan) for ease of use, buttery smooth operation and, crucially, maximised compatibility with off spec rails, I went with the ADM.
Along with my H1 mount, I went with an ADM to replace the LaRue, too:
Quality isn’t quite up there with the LaRue and it uses hex bolts instead of Torx. Also the uppermost two hex bolts screw directly into the mount ring, as opposed to the LaRue’s threaded steel inserts. The lower hex bolts have these inserts, so I can only think it’s a cost saving measure. The ADM mount was cheaper.
The real gem, as stated previously, is the QD mech. It locks solid with the lightest of touches and flows through its arc smoothly, when the locking latch is depressed. It is also highly compatible with non-spec RIS.
My ML2 is set up for right handed use – with the ML2’s battery tube on the upper right hand side of the subjective lens. An advantage of this ADM mount, is that the faces of the two uppermost mount ring hex bolts are 100% accessible on the side which is away from the battery compartment. That means you don’t have to unscrew the battery cap to install or adjust the orientation of sight in the mount.
