Bolt fails to lock open.

Well Hell! Got my AR 15/22 back from S&W. It goes back again tomorrow. Loaded 3 shells in 3 different magazines. First two mags locked open after the last round was fired. On the 3rd mag it failed to lock open and after that it never did lock open on the last round again. My friend was with me with his AR and I tried his 3 mags. Same results. Tried my mags in his AR and they worked just fine. S&W says they "MAY" replace it with a new one. Thoroughly disgusted with S&W and this rifle.
Now you might understand why, regarding simple problems and solutions, many enthusiasts prefer to perform the repairs themselves as opposed to dealing with the manufacturer. Good luck with it.

bamashooter with a new gun under warranty I feel I shouldn't have to solve "SIMPLE" problems myself. Maybe if more people would send them back to be repaired for the same problem S&W would find a fix and recall all the ones that need repaired. Just saying. Would you take a new car back for repairs that you could fix if it was still under warranty???

Or, they'll just stop making them Like Ruger did with their 10-22 WMR! :D:eek:
 
It works.

Just cut 1 coil and test with an empty mag. If it still fails, cut 1 more coil and guarantee it will lock back. just need a small punch and put the cut side toward the eject side or...... keep posting fails and stop asking for "HELP please!!" and not taking advice?????;)
 
When a gun of mine has been to the factory twice, they will never see it again, and neither will I.

However, I learned long ago that many aggravating little problems have simple solutions done at home. These work, and there is no reason not to follow the advice of others who have been successful with minor adjustments/repairs.

Stubbornness and pride have a cost in time, effort, frustration and aggravation. I won’t spend that capital on a $400 machine. If this thing otherwise works as it should, and cutting a little spring seems to be the fix, and you won’t do that, you are making your own problem worse.

Cut the spring.
 
ladebakk and CB3 what if i cut 1 or more coils off of the spring and it still doesn't work? What then? I'll try working with S&W till they say sorry or replace it. If S&W says live with it' then I'll sell it and get some other brand. I wouldn't feel comfortable working on any firearm of mine. Sorry if you think I'm STUBBORN or prideful but that's the way I feel.
 
Buy a spare spring, modify it, install the modified spring. It works? Viola! Problem solved. Save the factory original spring. If the mod doesn’t work on the aftermarket spring, reinstall the factory part and ship it back to S&W for warranty work. I have replacement parts for ARs on hand because they are moving parts and they do fail over time and use. For me, a big part of the enjoyment of owning my firearms is working on them, especially the plug and play parts of an AR. Just a suggestion. Small parts kits cost a couple bucks.
 
After S&W sent me 3 new magazines to try with the same problem happening, they finally agreed to replace it. The new AR 15/22 has been running like a charm without a single problem now for 7 months. It will eat any ammo I put in it. Thanks for your comments and help.
 
It seems counter intuitive but weaken the spring helps the lock back???


Right: The spring holds the bolt catch out of the way. If it's too strong relative to the mag springs, then the bolt catch never engages...

Want it done right?

Yes. And I've done so.
