BCM A/T Optic Mount for Aimpoint Micro T2
Mix and match across the range: 2 items save 5%, 3 save 10%, 4 or more save 15% on your whole basket.
Fits the Aimpoint Micro T2 only, mounted to any Mil-Std 1913 Picatinny rail on an AR-15/M4, including UK straight-pull AR-15 builds. Both versions take the same optic and differ only in optical centreline height: 1.63" (41 mm) for lower 1/3 cowitness, or 1.93" (49 mm). Maximum clamp torque 65 in-lb (7.3 Nm).

The BCM A/T Optic Mount is a one-piece 7075-T6 billet mount for the Aimpoint Micro T2, clamping to any Mil-Std 1913 Picatinny rail through BCM's angled-torque interface.
Both versions take the same optic. The only thing that changes is how high it sits — pick the height, then stop thinking about the mount.
Two part numbers, one optic. The OM-AT-21 puts the Aimpoint Micro T2's optical centreline at 1.63" (41 mm), which is the lower-third cowitness position on a standard AR-15 upper; the OM-AT-22 puts it at 1.93" (49 mm), the taller modern height that suits a more head-up posture, helmet and eye protection, or working under night vision. Nothing else differs — same optic footprint, same material, same clamp, same price.
The mount is machined from 7075-T6 billet and hard-coat anodised to Mil-A-8625F, with a hardened steel alloy clamp and a nitride-coated nut. BCM keeps the part count deliberately low, because every additional joint in an optic mount is another place for zero to move. Multiple integral recoil lugs engage the rail directly, and the whole assembly sits low and clean with nothing to snag.
The A/T is Angled Torque: a patented clamp that applies triangulating force rather than pulling squarely sideways, which BCM states delivers approximately twice the clamping force at the same torque as a legacy horizontal interface. Do not exceed 65 in-lb (7.3 Nm). On a UK straight-pull AR-15 — shot deliberately, worked by hand, and expected to hold the same zero across a season rather than across a magazine — a mount that does not move is the whole point. Made in the USA and covered by US Patent 12215956.
Fits the Aimpoint Micro T2 and mounts to any Mil-Std 1913 Picatinny rail on an AR-15/M4, including UK straight-pull AR-15 builds. Both versions accept the same optic, so choose on height alone: 1.63" gives lower-third cowitness with standard AR-15 iron sights, while 1.93" raises the sightline for a more upright head position, a helmet, or night vision. Tighten the clamp to no more than 65 in-lb (7.3 Nm) — the angled-torque interface generates roughly twice the clamping force of a horizontal one at the same setting, so over-torquing gains nothing and risks the hardware. If you want to raise an existing optic and mount rather than replace them, the BCM A/T Optic Riser adds 0.525" under whatever you already run.

£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.
No. Both are made for the Aimpoint Micro T2 and take the same optic. The only difference is optical centreline height: the OM-AT-21 sits at 1.63" (41 mm) and the OM-AT-22 at 1.93" (49 mm). They are the same price, so the decision is purely about how high you want the sightline.
1.63" is the lower-third cowitness height, so standard AR-15 iron sights appear in the bottom third of the optic window and your cheek weld is the traditional one. 1.93" raises the optic for a more head-up posture, which is easier to hold over a long deliberate string, and gives clearance for a helmet, eye protection or night vision. If you shoot with irons as a backup and want them in view, take 1.63".
No more than 65 in-lb (7.3 Nm). The angled-torque clamp triangulates its force onto the rail and produces approximately twice the clamping force of a conventional horizontal interface at the same setting, so the correct figure is lower than instinct suggests. Use a torque wrench rather than feel.
The multiple integral recoil lugs index the mount into the rail slots, which is what makes return-to-zero repeatable when it goes back in the same position on the same rail. As with any Picatinny mount, note which slot you were in and confirm zero after refitting rather than assuming it.
