The BCM 1913 Light Mount Modular is an ambidextrous aluminium light mount for AR-15 and M4 rifles, attaching to a KeyMod handguard and presenting a 1913 Picatinny stub for a weapon light.
This is the KeyMod version. The same mount is made for M-LOK handguards — check which handguard you have before ordering.
Instead of clamping the light body, this mount provides a short 1913 Picatinny rail section at the 3 or 9 o'clock position, so it takes any light built for a Picatinny interface rather than one specific body diameter. Change the light and the mount stays on the rifle.
It is fully ambidextrous, so a single part serves either side, and it offers an optional high and low mounting position for the 1913 rail section — useful for clearing a bulky handguard or bringing the light in tight against it. The body is low-profile aluminium and weighs 0.9 oz (26 g). Fitting uses a Torx wrench with the screws tightened to 30 in-lb, and Bravo Company USA suggest blue thread-locking compound if you want the fasteners secured.
Fits KeyMod handguards and forends on AR-15/M4 rifles, including UK straight-pull AR-15 builds. This is the KeyMod version and will not attach to an M-LOK handguard — for that, order the BCM 1913 Light Mount Modular for M-LOK, which is the same mount in the other interface. Once fitted it accepts any weapon light built for a 1913 Picatinny interface. If your light has a bare body rather than a rail clamp, the BCM Modular Scout Light Mount is the KeyMod mount that grips the body directly instead. No light is included.

This is the KeyMod version. The same mount is made for M-LOK handguards as the <a href="/products/bcm-1913-light-mount-modular-m-lok">BCM 1913 Light Mount Modular for M-LOK</a>. KeyMod slots have a round keyhole at one end; M-LOK slots are plain rectangles. Check your handguard before ordering — the two are not interchangeable.
The 1913 rail section can be fitted in either a high or a low position. Low brings the light in tight against the handguard for the slimmest possible package; high lifts it clear, which helps on a bulky handguard or when a light head would otherwise foul the rail.
Any weapon light built to clamp onto a 1913 Picatinny rail. Because the mount presents a rail rather than gripping the light body, it is not tied to one light diameter and it stays on the rifle when you change lights.
Bravo Company USA specify 30 in-lb on the Torx fasteners, and suggest blue thread-locking compound if you want them secured against vibration. Re-check the fasteners after the first session.
