Briley’s 45 Degree Offset Rib is an add on for Briley M-Lok handguards, offering a second sight picture for use around IPSC Barricades and as a backup to centerline iron or optical sights. The rib attaches to the 45 degree angled M-Lok slots on either the right or left side of Briley M-Lok Handguards for Benelli, Beretta, Franchi, Stoeger, and Breda shotguns. The Rib made from 6061-T6 aluminum, hardcoat anodized, and is equipped with a Truglo® Starbright fiber optic front sight in either Red or Green. At only 0.35” tall the rib will not impede normal function and handling of the shotgun.
14” Offset Ribs are perfect for the Benelli M2 14” Handguards, Beretta 1301 Competition Handguards, Franchi 16” Handguards, and Stoeger 16” Handguards.
10” Offset Ribs are perfect for the Benelli M2 10” Handguards, Franchi 12” Handguards, and Stoeger 12” Handguards.
When installing the ribs on the Stoeger or Franchi handguards, we recommend keeping the rib flush with the rear of the handguard for the best sight picture.
The ribs can be trimmed and the bead re-installed to fit a Benelli M4 8” or 13” Handguard. Tactical guns like the Benelli M4, Beretta 1301 Tac, or Beretta A300 Patrol may not be ideal for use with the rib because of the higher sight plane of the factory ghost ring sights.
10” ribs are attached with 3 M-Lok nuts, while 14” ribs have 4 M-Lok nuts. Hex head screws in pockets allow for an uninterrupted sight picture down the rib, and the included wrench allows for simple installation.
