Touching back on this thread. The A194 worked perfectly with my ar15 flattop and DMR2. Eye relief just a hair in front of charging handle, and mount sets scope turret centered between rings. I’ve got enough room for a bubble level front or rear of the turret as well. IMO, I can’t imagine a mount that would have worked out as perfect for me on this setup. Very pleased.
Although I was surprised the picatinny cross bolt on the mount is smaller than the actually slot on the ar flat top rail. Is this normal for top tier mounts?
