High-quality mount! - American Defense Manufacturing AD-RECON AR-15 1-Piece 2in Offset Riflescope Mount

I was a little nervous about ordering a mount like this that I've never tried before. But I am glad I did. I cannot say enough about the quality of the machining, finish, attention to detail, even the better-than-usual nitrided machine screws with the larger hex. The base mounted up true and dead-straight in every conceivable way with the rail on my upper and the scope (many cheaper mounts or rings will not do this). One tip: When loose, both sides of the ring sets are free-floating in terms of bore alignment, so when you get your scope in them, tighten all the bottom ring bolts first (22-ish inch pounds) and then the top bolts (15-19 inch pounds). This seems to work best for allowing the rings to align with the base, while minimizing movement of the scope after leveling everything. I'll definitely be buying more of these.
