Product Description
The Magpul ACR Stock is one of the most iconic and highly sought-after folding stocks ever made. Discontinued years ago and long gone from Magpul’s catalog, it has become a true unicorn on the used market—commanding serious prices and vanishing the moment one appears.
Haga Defense has secured a large stash of brand-new, never-mounted black folding Magpul ACR stocks. These are the real deal: high-impact composite polymer construction, rubber butt pad, 7-position telescoping length of pull, right-side folding hinge with detent, and a locking adjustable cheek weld that raises ½" for better optics alignment. Multiple sling attachment points (side-swappable QD coupler and single-point loop) are built in.
This is a limited release. When this inventory is gone, these brand-new Magpul ACR stocks are gone forever. No restocks. No more coming.
We are offering them two ways:
- As-is (stock only) — perfect if you already have a compatible adapter or want to use it on a factory ACR / compatible platform.
- With a Haga Defense adapter pre-installed — so you can put this legendary stock on a variety of modern platforms. Specific platforms are being finalized and will be listed as options become available. 1913 adapter is a for sure.
These are not used, not take-offs, and not clones. New Old Stock (NOS) Magpul ACR stocks from our reserved inventory.
