The B-10 recoilless rifle (Bezotkatnojieordie-10) (It is also known as RG82 in East Germany) is a Soviet 82 mm smoothbore recoilless rifle. It could be carried on the rear of a BTR-50 armoured personnel carrier. It was a development of the earlier SPG-82, and entered Soviet service during 1954. It was phased out of service in the Soviet Army in the 1960s, however it remained in service with parachute units at least until the 1980s.

It is fitted with a PBO-2 sight which has a 5.5x zoom direct fire sight and a 2.5x zoom sight for indirect fire.
