This superbly accurate VEX Barrel is ready for your custom rifle project. This Barrel offers a threaded muzzle so that muzzle brakes or sound suppressors can be fitted. Precision machined from 416R Stainless Steel, it includes a matched bolt machined from Carpenters 158 or 9310 Steel which has been magnetic particle and high pressure tested. It is machined to mate with the Compass Lake specification Chamber for highest possible accuracy. The barrel is matte finished to avoid varmint spooking glare, and is fluted to reduce weight, increase barrel surface, and add rigidity. The muzzle is threaded 1/2″ x 28 T.P.I. and is finished with an 11-degree competition crown to enhance accuracy. The assembly comes complete with the Barrel Extension, WW Free Float Handguard Barrel Nut, an installed Low-Profile Gas block and Gas Tube, and Thread Protector. Button rifling is 1 turn in 8 inches – right hand twist for optimum accuracy with a wide range of heavier .223 / 5.56mm varmint bullets. All top-quality Windham Weaponry parts – made in the USA.
