That little feller reminds me of my kids a couple of decades ago (maybe a little more). They used to have a ball cycling 3-1/2" floppies through my 386SX computer's drive when I was doing backups of the tiny hard drive.yz9890 said:I zero'd the sights and optic but Henry is handling the break in.
Try some Lake City M193 ammo or, at the very least, some USA commercial .223 ammo. It could be the action is short-stroking a bit.yz9890 said:Ihad 1 double feed and sometimes the bolt doesn't lock back on an empty magazine (on 3 different type and brand new magazines). my brother told me not to decide it's a problem until I've got a few hundred rounds through it and the BCG and the interior walls of the upper smooth out a bit. the bolt catch seems to just barely catch the follower but I can't make it miss when I load an empty mag in the lower and push it around and tilt the follower etc. i also don't see any scratches on the back of the followers where I'd expect if it missed. if it persists after 300-400 rounds, I'll change the catch. I hear the Colt one is a fraction longer. then I guess I look into short stroking if that doesn't work.

I had a problem with a whole batch of five 20-round PMag magazines not holding the bolt back after the last round fired. I found that there was a spot on the back side of the magazines (the primer end) that was causing part of the bolt catch to rub on the magazine shell. The follower/spring didn't have enough energy to push past the friction. Filing a little off the back of the magazines eliminated the rubbing and totally solved the problem. My five 30-round PMag magazines exhibited no such problem, by the way.
That youngster has been taught VERY well. For one thing, I noticed the absolutely proper finger position when not ready to fire. Then the hits with every shot topped that off superbly.yz9890 said:
There's another thing that I forgot.yz9890 said:good to know. I'll pull the follower out and check the inside of the mag. it happened on 2 USGI mags with anti tilt followers and 20 and 30rd magpuls. but mostly a 20rd pmag. and most of the ammo was LC M193 but I'll put the cheap stuff away until I get this figured out.

The followers in the 20-round PMags were just a little sticky when I would move them with a wood sliver (think 2"-wide yardstick) as a pusher. To improve things, I pulled the followers and springs out, lightly polished the sides of the followers and the insides of the magazine shells and then used some good paste wax to coat the inside surfaces of the magazine shells and the springs. After reassembly, the followers moved MUCH more smoothly when I pushed on them.
Since the smoothing/waxing and the trimming of the spot on the back of the magazines, every one has worked absolutely perfectly in my AR.
