Rear sight block for AK-type rifles
Implementations of a rear sight block for AK-type rifles are provided. In some implementations, the rear sight block may comprise an optic mounting interface and a sleeve. In some implementations, the optic mounting interface may be used to attach an optical gun sight to the rear sight block, and the sleeve may be used to secure the rear sight block to the barrel of an AK-type rifle. In some implementations, the optic mounting interface may include a rear sight notch therein. In some implementations, the rear sight block may further comprise at least one accessory mounting interface thereon. In some implementations, the accessory mounting interface may be used to position a flashlight, laser, and/or other firearm accessory on the left (or right) side of the rear sight block.
