friend of mine owns this rifle. been sitting in the back of his safe for a while now because he lent it to someone some how they did something that made a round explode out of the chamber. bolt.receiver and barrel are unscathed but i can see a small spring stuck out from the left side of the cocking peace. seems like its missing a retainer of some kind. sure enough if cocked and bumped it will let loose and uncock. does anyone know what peace is missing so i can get this working again for my friend? thanks so much and have a good day.
