Hitman hex heavy profile barrel 223w a hit w me! - Hitman Industries OPMOD HC223 AR-15 .223 Wylde Hex Profile Rifle Threaded Barrel

The hex configuration was so convenient in both adding my Yankee Hill Suppressor Muzzle device and in assembling the Upper Receiver. Hex profile also acts as flutes in providing more surface area for cooling while optimizing weight at 36.9ozs.

Broke in barrel with an extended 2x typical break in routine. Used a 5x Steiner Battle Sight to achieve the following MOA groupings using factory PMC X-TAC 62g M855 w 80f ambient temp. Trigger was a Franklin Binary AR-C1 (4.5#s +/-0.5#s) :

> 3.7 MOA for a 10 rnd shot group fired within 2 minutes using factory ammo w a 5x scope and a Franklin Binary Trigger
> 2.4 MOA for a 5 rnd shot group all within 1 minute suing factory ammo w a 5x scope and a Franklin Binary Trigger
