    Y’all are right! The bolt catch pin and spring are so badly peened it won’t fall out. I need to figure out how to get it out. Lol

    OK, so I lightly filed the edge until the pin and spring popped out. What do you guys think I should do? just file it smooth? Swap the bolt catch? What causes that peening? My gun has a shitload of rounds and I do a lot of reload drills (lots of 7-10 round mags to maximize reloads. Just wear and tear or...?

    Do you grip the gun by the magazine well? I've seen severe peening on bolt catches caused by people inadvertantly having pressure on it while the gun is cycling. Can you post some some pictures of the bolt catch? Also, replace the bolt catch, spring and plunger. If the parts are peened then they need to be replaced.

    Not typically. I have a little hands stop on the rail that keeps my hand near the tape switch. I will replace all the bits.

    Well guys! Y'all fixed it. I took it out and ran 100 rounds of PMC and 16 rounds of 77gr. Did a bunch of reloads to maximize bolt catch engagement and everything ran great. Basically, the bolt catch spring pin hole was peened and no longer allowed it to put any tension on the bolt catch. Never had that issue in 25 years of AR shooting. I did order that special gas tube but I haven't installed it since everything is running well.

    I knocked out the roll pin and removed the bolt catch. Then I took a small file and ran it along the perimeter of the pin/sping hole until the peened rim receded enough to release the pin and spring. Then I filed it back smooth. Then I replaced pin/spring and bolt catch. Works perfectly again.
