Description
The Accu-Tac M-LOK Spec-4 is built for prone and bench work on mid-height rifles and carbines, and its direct M-LOK attachment is the reason to choose it over a rail-mounted alternative. Rather than clamping to a Picatinny section bolted underneath the handguard, it slots straight into the M-LOK slots themselves, which removes a layer of hardware, lowers the bore axis relative to the ground, and leaves nothing protruding below the fore-end when the legs are folded. Setup and removal are correspondingly faster because there is no separate rail section to thread on or off.
The design traces its lineage to the BR-4 G2 platform, so the leg geometry and adjustment logic will be familiar to anyone who has run that bipod. Legs extend and lock at multiple positions, giving a height range that suits shooting off a bench or from the prone over uneven ground. The 70-degree lateral tilt accommodates cant in the terrain without forcing an awkward body position. At 18.5 oz, the Spec-4 is not a lightweight compromise piece — it is a full-capability support tool whose weight reflects the 6061-T6 aluminum and high-strength steel hardware used throughout the construction. The Type III hard anodize finish meets MIL-SPEC standards, which means the surface hardness is appropriate for field use rather than rack storage. Mounting hardware is included.
