The TAC-308A model series is given the A3 series stock, a 20" barrel with threaded cap, and a detachable box magazine. The 20" medium-heavy contour barrel is match grade with a 1-11 twist and polygonal rifling. The detachable box magazine allows for 1 to 5 cartridges (also available is a 10-round box). The A-3 stock features sling loops and an integral cheekpiece and LOP spacer system.
The TAC-308B is similar but fits the A-5 series stock with a 24" medium-heavy contour barrel with threaded cap and polygonal rifling. Magazine support is also a 5-round detachable box magazine supporting 1 to 5 cartridges or a 10-round box. The A-5 stock sports a buttstock, integral adjustable cheeckpiece, LOP spacer system and sling loops.
The TAC-308C also sports the A-5 series stock and 24" medium-heavy contour barrel with polygonal rifling sans the threaded cap. The TAC-308C works from a hinged floorplate system.
The entire TAC-308 family line relies on a proven Remington-style trigger action. The action is G-30 McMillan Short Action chambered for .308 Winchester. Scopes are optional. A Dura-Coat Metal finish is applied and is available in colors black, olive, gray, tan and dark earth. The pistol grip is nearly-vertical and integrated into the stock in the usual way. The bolt lever sits over the right side of the gun body. Optics (including night vision) and a bipod are optional accessories to all of the TAC-308 family.
