The ACE Arule stock delivers a lightweight, combat-proven AR-15 cheek weld without the bulk or weight penalty many shooters accept as inevitable. Engineered for entry-length buffer tubes, this billet aluminum stock combines precision machining with practical field design—the soft foam overtube contours to your face naturally, while a reinforced gusset at the receiver extension handles recoil stress at AR-15's most vulnerable point. If you're building a patrol rifle, CQB setup, or fighting-weight hunting gun, this stock cuts unnecessary mass without compromise.
Built from aluminum and finished in mil-spec black, the Arule uses precision-machined aluminum butt clamps that lock directly to the receiver extension tube. A machined sling mount is integrated into the design, eliminating the need for add-on hardware and keeping your cheek weld clean. The entry length works well for shorter stock-to-grip distances on compact builds and is a natural fit for standard-profile buffer tube systems. What you don't get is extra weight or complexity—just solid engineering where it matters.
One practical note: the Arule arrives without buffer or spring, so plan your parts kit accordingly if you're starting from a bare lower. Your choice of .5" or 1" recoil pad ships with the stock, letting you dial in length of pull to your preference. This is the kind of gear that disappears into your rifle—you notice it when it's wrong, but a good stock like this one just works.
| Brand | ACE (Doublestar) |
| Model | Arule Stock (A145B) |
| Compatibility | Entry-length buffer tube AR-15 systems |
| Material | Billet aluminum |
| Finish | Black |
| Recoil Pad Options | .5" or 1" |
| Includes | Stock, buffer tube, recoil pad; buffer and spring NOT included |
The Arule is designed for entry-length buffer tube AR-15 systems. It requires a standard receiver extension tube and is not compatible with pistol-length or rifle-length buffer systems. Confirm your buffer tube length before ordering.
Yes. The Arule stock and buffer tube ship without a buffer or spring—you'll need to source those components separately for a complete assembly.
You get to choose one pad with your order. The .5" pad is slightly shorter and reduces overall length of pull; the 1" pad adds more length. Pick based on your preferred stock-to-grip distance and shooting position.
The sling mount is machined directly into the aluminum butt clamps as part of the stock design—it's ready to use with no additional installation.
