The BCM Modular Scout Light Mount is an ambidextrous aluminium weapon light mount for AR-15 and M4 rifles, attaching directly to a KeyMod handguard and clamping the light body itself.
The whole buying decision is the body diameter: this mount fits lights measuring 0.825 to 0.832 in (21.0 to 21.1 mm) across the barrel, and nothing else.
Unlike a mount that presents a Picatinny stub for a light with its own rail clamp, this one grips the light body directly, which is why it sits so low and so close to the handguard. The price of that is a fixed diameter: Bravo Company USA specify a nominal 0.830 in body with a working range of 0.825 to 0.832 in (21.0 to 21.1 mm). Measure your light before ordering. A body outside that range will either not close or will not clamp.
Within that range it is a genuinely modular mount. It is fully ambidextrous, so it works at the 3 or 9 o'clock position without buying a handed version, and multiple mounting holes let you slide the light fore and aft to put the tailcap where your thumb actually falls. The body is aluminium and weighs 0.5 oz (14 g).
Two things have to be true. First, the handguard must be KeyMod — this mount attaches to KeyMod slots and will not fit an M-LOK or Picatinny handguard. Second, and more importantly, the light body must measure 0.825 to 0.832 in (21.0 to 21.1 mm) in diameter, a nominal 0.830 in. Bravo Company USA name the SureFire Scout Light M300 MINI, M600AA, M600 ULTRA, M600P FURY, M300V MINI and M600V as fitting, along with Streamlight tactical models including the ProTac 350 and TacPro. If your light is not on that list, measure the body before ordering rather than assuming. It suits AR-15/M4 rifles including UK straight-pull AR-15 builds. Torque the light clamp screws to 25 in-lb and the KeyMod fasteners to 30 in-lb. No light is included.

£5 tracked UK delivery on every order via Royal Mail Tracked 24. Our products are ordered in from the manufacturer rather than held in UK stock, so please allow 7 to 10 business days (Monday to Friday, excluding bank holidays) from the date of your order for it to reach you. Tracking details are emailed on dispatch. UK delivery only.
You have 30 days from receiving your order to cancel it for any reason, then 14 days to send it back unused and in its original packaging. Faulty, damaged or incorrect items are replaced or refunded and we cover reasonable return postage. Refunds go back to your original payment method within 14 days of receiving the return.
Only if its body measures between 0.825 and 0.832 in (21.0 to 21.1 mm) across, a nominal 0.830 in. Bravo Company USA name the SureFire Scout Light M300 MINI, M600AA, M600 ULTRA, M600P FURY, M300V MINI and M600V, plus Streamlight models including the ProTac 350 and TacPro. If your light is not one of those, measure the body with calipers before ordering — this mount grips the body itself, so the diameter is not negotiable.
No. This is the KeyMod version. KeyMod slots have a round keyhole at one end; M-LOK slots are plain rectangles. If your handguard is M-LOK you need a different mount.
Then you want a mount that provides a Picatinny stub instead. The <a href="/products/bcm-1913-light-mount-modular-keymod">BCM 1913 Light Mount Modular for KeyMod</a> puts a 1913 rail section at 3 or 9 o'clock and takes any light built for that interface.
Bravo Company USA specify 25 in-lb for the screws clamping the light and 30 in-lb for the KeyMod fasteners. Do not overtighten the light clamp — it is gripping an aluminium light body, not a steel rail.
