Sinclair AR-15 protective sight covers and muzzle guards protect your AR-15's front and rear sights from being moved or damaged. The muzzle guard keeps dirt out of your barrel and provides protection to the muzzle crown. Covers are made of durable vinyl and fit snugly to the sights and muzzle. Each set includes a front sight cover, a rear sight cover, and two muzzle guards designed for AR-15's with or without a flash suppressor.
