  • Builders wanting to choose their own suppressor or muzzle device
  • Versatile shooting requiring gas system adjustability

Suppressor Ready with 5/8x24 Threading: This pistol does not include a muzzle device, making it suppressor ready out of the box. The 10.5-inch barrel features 5/8x24 thread pitch—the standard threading for .300 Blackout suppressors and muzzle devices. Simply attach your suppressor directly to the threaded barrel without the need to remove a factory muzzle device first. This configuration is ideal for shooters who plan to run suppressors full-time or want the flexibility to choose their preferred muzzle device without dealing with pre-installed components.

Adjustable Gas Block for Suppressed & Unsuppressed Shooting: The premium adjustable low-profile gas block allows you to tune gas flow for optimal performance with both suppressed and unsuppressed configurations. When shooting suppressed, additional back pressure can cause over-gassing—the adjustable gas block lets you reduce gas flow for smoother cycling, reduced recoil, and less wear on components. When shooting unsuppressed, open the gas block for reliable cycling. This adjustability makes the Mutton Chops capable for both sport shooting and tactical applications where suppressor use may vary.

4150 CrMoV Barrel & Pistol-Length Gas System: The 10.5-inch barrel made from 4150 CrMoV steel with phosphate finish provides durability and corrosion resistance for long-term use. The 1:8 twist rate is suitable for a variety of ammunition, ensuring proper stabilization of .300 BLK projectiles from lightweight 110-grain supersonic rounds to heavy 220-grain subsonic bullets. The pistol-length gas system provides efficient operation with .300 Blackout's pressure curve, delivering reliable cycling with both supersonic and subsonic loads across the ammunition spectrum.

Premium Components with SBA3 Adjustable Brace: The AR-15 "Panhead" billet upper receiver constructed from anodized 6061-T6 aluminum offers precision machining and durable construction. The lightweight black KeyMod freefloat handguard allows for customizable accessory attachments including lights, lasers, and foregrips while eliminating barrel contact for improved accuracy. The 9310 alloy steel BCG with nitride finish provides enhanced longevity and lubricity for reliable cycling. The stable SB Tactical SBA3 adjustable pistol brace features five positions of adjustability, adding versatility and improved control, making the Mutton Chops a capable choice for demanding shooting applications where adaptability and performance matter most.
