Shadow Silencers

The Penta from Shadow Silencers is our purpose built 556/223 product optimized for AR rifle applications and is the most versatile and rugged in its class. The Penta is a 5 baffle system made of our unique parabolic and M-Cup baffles that aids in the barrel harmonics and ballistics that are unique to AR rifle shooting, and is hearing safe out of the box. Made from 7075 billet aluminum completely Milspec 3 hard anodized and 6AI-4V Titanium, the Petna is built to last, and run a minimum of 35% cooler than other like products on the market. At 8.0 inches, 13.8oz (full stack) with an OD of 1.575 inches the Penta is comfortable on many types of AR rifle applications and durable enough for the toughest conditions.

Optimized for 5.56NATO/.223Rem but you're also able to run .17 (all rimfire), .22 (all rimfire) and 5.7x28.

Threaded for direct mounting on barrels with a thread pitch of 1/2x28 but compatible with a whole hose of adapters.

A word on the Milspec 3 finish, which is a real game-changer.  The aluminum is hard coat anodized (both inside and out), which increases wear and corrosion resistance, increases surface hardness, increases the thermal properties of the aluminum and improves the ability of the metal to retain lubricants. In other words, it changes the surface to this incredibly hard metal without increasing weight.
