Blue Force Gear Bfg A2B-Bk Vcas Buttstk Adpter

The Blue Force Gear A2B buttstock adapter is a simple, smart fix for AR-platform rifles that addresses a real-world problem: sling attachment points on the bottom of A1, A2, and A4 stocks tend to flip the rifle upside down during sling transitions and movement. By repositioning your sling connection to the top of the stock, the A2B creates a more natural carry angle and keeps your rifle oriented correctly when you need it most. It's an ambidextrous solution that works with any AR-15 or M16 platform buttstock in this family, making it practical whether you're running a two-point sling for tactical work, hunting, or range use.

Installation is straightforward: the adapter band clamps onto your existing stock without permanent modification. Once you've got it mounted and tightened down, you can tuck the excess strap material into the integrated hook-and-loop tab for a clean, snag-free setup. The A2B plays especially well with combat-proven two-point slings like the Blue Force Gear Vickers Combat Applications Sling or Victory Two-Point Sling, though it's compatible with any sling design that uses standard attachment hardware.

If you've wrestled with a rifle that won't stay muzzle-up when slung or found yourself constantly rotating your gun back into position, this adapter solves the geometry problem at its root. It's the kind of no-fuss improvement that makes you wonder why you didn't install one sooner.

Frequently Asked Questions

Will the A2B buttstock adapter work with my AR-15 platform rifle?

Yes, the A2B is designed for M16 and AR-15 platforms using A1, A2, or A4 style buttstocks. If you have one of those setups, it will fit without modification.

What slings work best with this adapter?

The A2B is engineered to pair with two-point sling systems, and Blue Force Gear specifically recommends it with their Vickers Combat Applications Sling or Victory Two-Point Sling. That said, it's compatible with any sling that uses standard attachment hardware.

Do I need a gunsmith to install this?

No. The A2B is a clamping band that installs directly onto your buttstock without permanent modification or special tools. Once mounted, tighten it securely and tuck any loose strap material into the hook-and-loop tab.

Why move the sling attachment to the top of the stock?

Standard bottom-mounted sling attachments create leverage that rotates your rifle barrel-down when you transition the sling or move dynamically. Mounting the attachment point to the top keeps the rifle oriented naturally and reduces the tendency for it to flip upside down.
