The AlleyCat 308 in Inconel is the durability focused version of the company's 30 caliber can. Inconel earns its keep in environments that destroy ordinary materials, and inside a rifle suppressor that means baffles that hold their shape and their performance no matter how fast the round count climbs. If your idea of a range trip involves more magazines than most people bring ammo, this is the material you want between you and the muzzle blast.The QD mount makes the can practical to share across a stable of rifles. Lock it on the 308 for one stage, move it to the 300 BLK gun for the next, and count on the mount to bring it back to the same lockup every time. The 30 caliber rating covers the common centerfire rifle spread. Between the alloy and the mounting, this configuration of the AlleyCat 308 is squarely aimed at shooters who use their gear hard and expect it to keep up.
