The Barrett Model 98B's modular layout allows the end user to adapt the rifle to fit their exact needs. The straight-line design running from the muzzle to the shooter's shoulder tames felt recoil. The ergonomic pistol grip positions the shooter's hand in a natural position, promoting the utmost control over the fully adjustable trigger. The familiar thumb-operated safety is accessible without compromising the firing grip, allowing the shooter to maintain a solid cheek-weld on the adjustable cheek piece while manipulating the oversized bolt handle, feeding a fresh round into the chamber as the bolt silently glides through a polymer guide. Optics and accessories are easily mounted to the aluminum upper receiver, which boasts an 18 inche 1913 rail as standard equipment. The forward receiver drilled and tapped for additional accessory rails to be mounted at the 3, 6 and 9 o'clock positions. The fluted, match grade barrel is easily acessed fro cleaning from the chamber by breaking the rifle open much the same way as a M4 Carbine. Barrel cooling is aided by a series of vents machined into the upper receiver.
