B&T APC ACR™ Adapter

(7 reviews) Write a Review

NEW! Gen 3 ACR adapters for the B&T APC now include an interface to mount the factory ACR sling bracket should you choose to use it (bracket not included unless you order the ACR stock assembly from Haga Defense as well. Otherwise it can be transferred from your old ACR Stock hinge). Other improvements include better takedown pin fit and revised hinge geometry for easier operation when locking closed.

Adpatper for mounting the Magpul ACR™ stock or brace to your B&T APC Firearm.

There are two variants for this adapter. One for the pistol caliber APCs (.45, 9mm) and one for the rifle caliber APCs (.223, 5.56mm, .300, .308). Be sure you add the correct one to your cart.

Notice: The part is designed for rifle caliber APCs but will also fit the pistol calibers. When used with pistol calibers the adapter design will not flow as seamlessly with the lines of the gun as it does with the rifle calibers. There will be a slight gap and overhand where the adapter meets up with the lower recceiver but will otherwise fit and function fine.

The rifle and pistol variant are the same physical part but the pistol version will include a 3d printed spacer for the recoil spring.

Will fire folded.

Machined from 6061 aluminum and hardcoat anodized black (Mil-A-8625 Type III Class 2).

Installing ACR™ stock requires a 3/16" roll pin punch.

*Magpul ACR™ stock NOT included but can be purchased separately from our Stocks and Braces page.

*Buffer spring not included. Can be removed from your factory part by knocking out the roll pin that runs side to side through the buffer. Reuse this roll pin when swapping the buffer assembly to the new part.
