Mesa Precision Stainless Steel 20 MOA Picatinny Rail

20 MOA Stainless steel picatinny rail precision machined to fit the Mesa Precision muzzle loader actions. These were made from necessity, as with these hard recoiling muzzle loaders, we feel an aluminum picatinny rail will not hold up over the long haul. Machined from solid bar stock 416R stainless steel, bead blasted and supplied with four 8-40 mounting screws and 2 locating pins. The locating pin holes do not protrude through the top of the rail. The supplied screws are .250 under the head and use a T15 driver.
