Early Benjamin 310 rifle 2 piece bolt. This bolt will also fit some 312 models. If your 312 rifle has a pistol rear sight that was made between 1953-1955 this bolt should work. Will not work on 312 models with the dovetail rear sights. Made of stainless steel to prevent rusting.  Bolt knob is made a tad longer. For 310 rifles made between 1939-1955.  Bearing & spring, lug screw inculded. This auction is for 1 bolt only. 

Benjamin 312-310 rifles made after 1955 that had a 1 piece bolt, this 2 piece bolt should work.
