BCM Lower 1/3 A/T Optic Mount for Aimpoint Micro T2

This BCM Lower 1/3 A/T optic mount provides a low-profile mounting position that places a red dot optic in lower 1/3 co-witness. It is designed for Aimpoint Micro series red dot optics and built to improve rail interface retention compared with legacy horizontal clamp designs. The mount is machined from billet aluminum and finished for corrosion resistance, with hardened steel clamp hardware for robust clamping and torque retention.

Key Specifications

• The mounting position provides lower 1/3 co-witness for red dot optic alignment.
• Constructed from 7075-T6 billet aluminum.
• The finish is hard coat anodized per MIL-A-8625F.
• The clamp and nut are hardened steel alloy with Nitride coating.
• The design incorporates multiple integral recoil lugs to help preserve zero.
• Uses an A/T (Angled Torque) patented-style clamp with a serrated locking spring-washer to retain torque under field conditions.
• The A/T interface delivers approximately twice the clamping force at the Picatinny rail versus a legacy horizontal interface with equivalent load.
• Color is Black.
• Fitment target is the Aimpoint Micro series of red dot optics.
• Product type is Optic Mount.

This mount offers a compact, durable platform for mounting Aimpoint Micro-style optics where a lower 1/3 co-witness is desired. Its billet construction, robust clamp hardware, and A/T interface are intended to provide consistent clamping force and improved retention for routine use in demanding conditions.
