We have found that some recievers have a square lug cutout, while some have a lug with radiused corners. Our lug is cut square and may require minor filing to fit in the recievers with radiused lug cuts.
Picatinny cross slots run the full length of the rail, which gives the shooter flexibility when mounting scope rings and other accessories. The cross slots are also machined the full width of the mount and gauged to MIL-STD 1913 specs maintaining tolerances of +/-.002″.
After machining; the mounts are tumbled and sand blasted. The aluminum mounts are Type III hard coat anodized for long lasting durability. The steel rails are Mil Spec parkerized for a durable rust resistant finish.
