Build a clean, lightweight AR pistol setup with the BATTLEARMS SABERTUBE Direct to Receiver Mid-Length Pistol Receiver Extension. Precision-machined for a distinctive profile, this purpose-built buffer tube combines functional design with durable materials for a streamlined addition to your compatible firearm build.
Designed for platforms that do not need to capture a rear takedown spring with an end plate—including AK, MPX, MCX, and similar systems—the SABERTUBE attaches directly to the receiver. Its integrated design eliminates the need for a castle nut, while the stepped-down outside diameter at the end is compatible with the Gear Head Works Tailhook MOD 1. This is a pistol receiver extension, not a stock.
