This factory SD suppressed SBR package pairs the mini FIX action with a dedicated titanium silencer that nests beneath the extended handguard for a compact, balanced footprint. It is classified as two NFA items — SBR and suppressor — and requires two tax stamps for transfer.
The action is a short-throw bolt design feeding from AR-15/M4 pattern magazines. Chambered in .300 AAC Blackout (7.62x35mm), it uses an 8 in stainless steel barrel with a 1:5 twist. Capacity is 10+1 with the included magazine.
The folding aluminum stock provides a height-adjustable cheekpiece, adjustable buttpad, and adjustable length of pull; the listed length of pull is 14.0 in. A two-stage trigger with a flat shoe and a Magpul MOE-K grip round out the controls.
The Q-SERT free-float extended aluminum handguard includes internal heat shields and a flush, integrated Kickstand bipod. A full-length 12 o'clock Picatinny top rail provides continuous mounting space along the receiver and handguard.
The two-tone grey/tan finish extends across the aluminum receiver and handguard. The top of the receiver block is factory-engraved with the outline of New Hampshire and 'LIVE FREE OR DIE.' Made in the USA, the rifle weighs approximately 5 lb 12 oz.
