Anderson Manufacturing AR15 20" Front Sight Based Barrel 5.56 1:9 Twist Rifle Length Gas System

• Anderson's 20'' FSB Barrel, featured on the A4 Rifle, brings many advantages to your rifle. This 20'' barrel gives the round more time to accelerate, giving you increased muzzle velocity, increasing effectiveness on long-range targets.

• The rifle-length gas system makes the gas travel further which effectively reduces the felt recoil and internal wear on parts like the bolt carrier group.

• The 20'' FSB Barrel gives you a longer sight radius to enhance accuracy.

• This barrel comes with a triangle handguard cap and an A2 Barrel Nut.
