The Double Star ACE ARFX-E is a fixed-length skeleton stock purpose-built for AR-15 platforms where compact handling matters. At 7.25 inches without the buttpad, this entry-length stock shines in close-quarters shooting, tactical training, and short-barreled rifle builds where you need maneuverability without sacrificing control. The skeletal design strips away unnecessary weight while the 6061-T6 aluminum frame—heat-treated and hard-anodized to mil-spec—delivers the rigidity needed for real-world use.
Built from aircraft-grade aluminum and finished in matte black Type 3 hard-anodize, the ARFX-E handles the demands of CQB work and dynamic shooting without compromise. This isn't a lightweight compromise; it's a purpose-driven design for shooters who run short platforms or need a stock that won't catch on body armor, plate carriers, or tight doorways. The fixed length means no adjustment hassle—you dial it in once and it stays put.
Installation is straightforward: you'll need a standard carbine buffer and carbine buffer spring (not included). The package comes with a foam-over-tube design for cheek contact, the buffer tube itself, and all necessary mounting hardware. If you're building a pistol-length or short-stroke AR for CQB, precision rifle work in confined spaces, or just prefer a minimalist platform, the ARFX-E is a solid, no-nonsense choice.
