The Build Story
5.56 in a package this short
Eight inches of barrel doesn’t leave much room for the 5.56 round to develop velocity. That’s exactly the point. This platform prioritizes maneuverability over terminal distance, in the same class as our .300 Blackout pistol but chambered in the most accessible, affordable round on the market. It runs reliably suppressed or unsuppressed, braced for one-handed control, and sized to live in a pack or a truck. Available in pistol or SBR configuration, built to your legal status and use case.
Same discipline, different caliber
Every part of this build mirrors the engineering of our 8” .300 Blackout pistol: pistol-length adjustable gas, suppressor-ready threading, enclosed optic, offset light. The Holosun HE508T enclosed titanium dot is zeroed and co-witnessed before it ships. The Streamlight rides offset to keep the geometry clean and the controls reachable. Nothing is bolted on as an afterthought. This is a complete system, not a bare lower with a parts list attached.
Hand-assembled and proven before it ships
Hand-built, torqued to spec, and run through a live-fire shakedown, unsuppressed and suppressed if you’re adding a can. We built this for the shooter who needs 5.56 availability and pricing without giving up the compact, proven platform that makes an 8″ AR pistol worthwhile.
