3.73″ Picatinny Rail – Scope Cap Mount – Gen 2

Description

3.73″ Picatinny Rail – Scope Cap Mount. GENERATION 2

Hard-coat anodized, 3.73″ length, 9-slot Picatinny rail that mounts on top of F3R Machine scope caps via 8-32×1/4″ Torx-Plus screws (2x included). These accessory rails will sit flush with one end of the scope cap, and extend past the other end.

Overall dimensions: (L x W x H) 3.732″ x 0.835″ x 0.925″

Weight: 1.6 oz (including 2 cap-screws)

NOTE: A Torx wrench is not included with these mounts – you’ll need to use the T25 Torx-Plus wrench that came with your F3R Machine one-piece scope mount. A regular T25 Torx wrench will work also. Torque Spec = 20 in-lbs.

IMPORTANT NOTE: See photos for clarity. Early versions of our F3R Machine scope caps (Generation 1) did not include the slot in the scope cap to locate the alignment lug of the accessory rails. Please look at your scope mount and determine if it is Generation 1 (no top slot, just threaded holes) or Generation 2 (top slot and threaded holes). All of the one-piece scope mounts that F3R Machine currently offers are the Gen 2 version with the alignment lug slot on the top caps. Currently, these 3.73″ accessory rails are only offered in the Gen 2 version, and will not fit Gen 1 scope caps.
