I have owned a lot of equipment made by RRS and they are great. The M-Lok adapter was exactly what I needed.
The BMLOK-60 plate comes with removable stop screws to ensure a non-slip mounting point while firing heavier recoil platforms. The semi-permanent plate incorporates a 1.5" dovetail fully compatible with the standard RRS quick-release clamps and heads. CNC machined from solid 6061 T6 aluminum block and type-3 hard anodized, the BMLOK-60 is built from the ground up for maximum functional performance, ruggedness, ergonomic fit and finish.
