An AR-308 handguard is a rail or free-floating part built for AR-10/AR-308 rifles in .308 Winchester or 7.62×51 NATO. You get a firm grip and space to mount gear like lights, grips, and lasers. The handguard fits AR-308 upper receivers, .308 barrels, low-profile gas blocks, and gas tubes. Common rail systems such as Picatinny, M-LOK, and KeyMod are all supported. This part is key for building out, protecting, and boosting the use of your AR-308 rifle.
