    How is the bolt recoil spring tube plunger piece kept inside the stock tube, so the bolt can be removed without it following?

    My cajon budy broke the stock tube by throwing the shotgun on the groun!!!

    From my observations, I need to peen or punch the threaded end of the tube inward to retain the spring plunger.

    The forward end of the tube is smaller in diameter than the base of the plunger.

    Thanks, I made a small sleeve to stop the spring plunger. The plunger will not make contact with the sleeve until the bold assembly is removed. Next time , I will swedge the end down and then thread. When a CoonAss throws a AL-391 on the ground something will brake!!!!!

    That should work as long as it doesn't extend forward too much. If it extends forward too much, it would get battered by the rear end of the bolt slide during the bolt's rearward travel.

    Easystreet,

    I saw that and kept the sleeve flush with the face of the threaded end. The plunger end is .465" diameter and extendes in front of the two .522" pilot diameters by .600". Thats why I made the sleeve only .200" long. Since the Beretta, is my hunting buddy's, I will be able to keep an eye on it! The part was $100.00 from Beretta, my show only charged two cases of Budweiser!!!!
