Breech Bolt Assembly Question

Post by Davegmc » Sat Jun 22, 2019 3:28 am

Hello: I recently purchased a used 870 Super Mag 12 gauge. When I did a basic breakdown to thoroughly clean it the "Locking Block Assy" (part number 37 in the manual) just fell out of the Breech Bolt. When I looked at some of the take down videos on Youtube (by Synchronizor and others), it appears that that Locking Block did not come loose during breakdown. The gun seems to operate fine but I'm thinking that part should have better retention in the bolt? Any help would be greatly appreciated.

It only goes in one way and is somewhat ‘loose’.
