Dead Air Sandman K Suppressor with QD Mount: The included Dead Air Armament Sandman K suppressor utilizes a QD (quick-detach) mount for quick attachment and removal, allowing fast transitions between suppressed and unsuppressed configurations. The Sandman K is renowned for its durability, sound suppression, and minimal point-of-impact shift, making it a premium choice for .300 Blackout applications. The QD mounting system provides secure, repeatable lockup that maintains zero even when repeatedly attaching and removing the suppressor—ideal for shooters who need flexibility or share suppressors across multiple firearms.
1:8 Twist Rate for Maximum .300 BLK Versatility: The 8.5-inch heavy profile barrel features a 1:8 twist rate, providing optimal stabilization across the full range of .300 Blackout projectiles. This twist rate handles everything from lightweight 110-grain supersonic rounds delivering maximum velocity to heavy 220-grain subsonic bullets optimized for suppressed shooting. The 1:8 twist is considered the ideal compromise for .300 BLK, ensuring consistent accuracy and reliable stabilization regardless of bullet weight or velocity—essential for a platform designed to excel with both supersonic and subsonic ammunition types.
Premium Adjustable Gas Block for Suppressed Optimization: The premium low-profile .750 adjustable gas block ensures reliable operation by allowing precise tuning of gas flow for suppressed or unsuppressed shooting. When using the Dead Air Sandman K, adjust the gas block to compensate for increased back pressure, reducing bolt carrier velocity for smoother cycling, decreased recoil, and extended component life. The adjustable design ensures optimal performance across different ammunition types and shooting conditions, from full-power supersonic loads to light subsonic ammunition—critical for maximizing the versatility of the .300 Blackout platform.
Premium Construction & SBA3 Stability: Built on a robust 7075-T6 aluminum upper receiver for superior strength, paired with an M-LOK freefloat handguard constructed from 6061-T6 aluminum providing a lightweight solution while maintaining strength for accessory mounting. The Parkerized barrel finish offers durable corrosion protection, while the 5/8x24 threading is the standard for .300 Blackout suppressors. The mil-spec heavy-duty 6-position buffer tube and SB Tactical SBA3 adjustable pistol brace provide stability with five-position length of pull adjustment. This complete build is perfect for shooters and gunsmiths who appreciate precise craftsmanship and performance in their firearms, delivering a turnkey suppressed .300 Blackout pistol with Dead Air quality, adjustable gas operation, and compact versatility for demanding applications.
Disclaimer: All firearms are test fired without suppressors installed. When adding a suppressor, you may need to tune your setup to ensure proper function and reliability.
