We have discussed this before- Sears had a recall of their bolt action 12 g shotguns- and the defect was described as: "The retailer said it is recalling the J.C. Higgins bolt action 12-gauge shotguns due to a potential problem with the bolt latch assembly. A spokeswoman for Sears said if the assembly failed, the bolt latch could dislodge and strike the operator in the face." When being cycled, the bolt was retained in the gun by a set screw on the left side of the action. A number of folks have described the problem as a missing set screw, and that the bolt had been pulled from the gun when cycling it. HOWEVER- other information indicates that the failure was much more serious- the bolt is latched in battery by a shoulder of the receiver that butts against the base of the bolt handle. Due to the design, when material is milled away for the 12 g (only!) there is not enough left to reliably withstand the force exerted on firing. The metal is sheared off, bolt blown back, shearing off the set screw, and whacking shooter in the face. Here is what one looks like when it fails- You can see where the metal has sheared away. Before it fails. Some folks will feel it is still OK to shoot these. I don't.
