Excited to have, and pleased with the construction of my new 392S. Keeps my beautiful wood stock 392PA from being lonely.
Arrived right from the factory. However when turning the bolt handle down to lock into battery, the handle is very tight. Tightening as it goes farther down to full close. I removed the bolt to look for burrs (none) and applied a couple drops of Pellgun oil but the only way to make the bolt handle close snugly, firmly and without any grinding feeling was to remove the two retaining screws holding the cam plate and cover plate. Using blue Loctite I reinserted them and just lightly screwed them in. Thing is, with time the cam plate could loosen and cause air loss on firing. I suspect that the two screws, when snugged down too much, protrude through into the receiver and bind the bolt.
The cover plate is a thin stamping that was a little flexed from the factory tightening so if it was meant to function as a tensioner to keep tension on the two screws it's not doing it. I'll remove the bolt again to see if the steel screws scratched the bolt as it rotates into locked position. Sure hop not.
So. Would very small washers stacked under the screws, reinforced with blue Loctite , and firmly tightened down work to prevent cam plate movement and bolt binding when the optimum thickness is found?
Thoughts sure appreciated and thanks.
