You might say no way you can get full-length rifle performance out of a carbine. Those that know about 8.6 BLK would beg to differ though. Utilizing a fast barrel twist the DISSENT Mk3 launches the burly .338 caliber projectiles with purpose and speed. Whether you use supersonic ammo for big game or subs with a suppressor for maximum hush factor, 8.6 BLK sets the bar high.
If you’re looking to shoot suppressed or just fine tune your DISSENT to your preferred ammo, the adjustable gas block gives you the freedom to dial in the gas system exactly to your liking. Never too much and never too little.
