HM Defense Stealth300 Features
This rifle’s standout feature is the patented integrally machined MONOBLOC gas block and suppressor, eliminating the need for traditional gas block installation, tuning, or alignment. The suppressor is machined into the barrel, removing the risk of backoff or baffle strikes and eliminating the need for external mounts or adaptors. Built to perform in the harshest conditions, the Stealth300 includes a preset gas system optimized for both subsonic and supersonic ammunition, eliminating the need for adjustable gas blocks or heavy buffers.
Transitioning between subsonic and supersonic ammo is seamless, with no rail removal or tuning required. The rifle’s baffles are crafted from heat-treated H900 17-4 stainless steel, offering durability and efficient sound suppression. With no welding, pinning, or joining involved, the Stealth300 represents a compact, reliable solution for suppressed shooting.
