Bravo Company Manufacturing AR-15 Gas Block - F-Marked Front Sight Base - .750"

The Bravo Company Manufacturing AR-15 Front Sight Base is an "F"-marked gas block built to bring a flat top upper up to mil-spec sighting height. Built for .750" barrels, this front sight base aligns correctly with mil-spec rear iron sights instead of sitting too low the way a non-F-marked base would on a flat top receiver.

Features:

• "F"-marked for correct height on flat top uppers
• Fits .750" barrels
• Aligns with mil-spec rear iron sight height
• New, undrilled for taper pins
• Front sight base only; no sight post or taper pins included

Because the base ships undrilled for taper pins, installation requires a qualified gunsmith to drill and pin it to the barrel correctly; this is not a drop-in part for a home build. Using an F-marked base on a flat top upper matters for sight co-witnessing, since a standard (non-F-marked) base sits too low on a flat top receiver and throws off the alignment between the front post and a mil-spec rear sight. This listing includes the front sight base only, without a front sight post or taper pins.

Bravo Company Manufacturing designs and builds rifles, uppers, and small parts for military, law enforcement, and civilian shooters, machining its components to tight mil-spec tolerances. BCM's gas system parts are built to hold up to the heat and pressure of hard rifle use over the long term.
