3DX Strongarm™ Adapter for ACR™

(No reviews yet) Write a Review

The first product from The 3D Experiment to hit shelves courtesy of Dan Haga Designs. This brace host will fit onto a Bushmaster/Remington ACR™ stock converting it into a pistol brace with the addition of the DoubleStar Corp. StrongArm™ Pistol Brace. Made from Multi Jet Fusion (MJF) Nylon which is exceedingly tough and black completely through the part. The 3D Experiment brace host has new aesthetics with lines that flow more fluidly with a wide variety of firearms. This specific adapter is stippled to match that of the Grand Power Stribog.

Installation: Button locks, springs, pins and stop screw are to be reused from the factory ACR™ piece. This process requires punches, a hammer and some patience. I do offer free installation, message me for details.


*ACR™ stock and Strongarm™ brace NOT included. Both can be purchased separately from our accessories page.
