Bushmaster safety lever

[firesafety3]

So I am towards the end of my second shooting session with the Bushy. Everything is going nicely until I go to put the rifle on "SAFE" to check impact on the target. The lever won't move, just stuck in the 12 o'clock position.

I should have one round left in the mag so I reshoulder and...nothing. Trigger won't pull, safety lever won't move.

I eject the mag, clear the round, bring the bolt forward a few times, and began to look for anything amiss. With nothing found, I reinsert a full mag and load the chamber. Two rounds go down range fine then another "lockup".

I separated the upper to see if something may be interfering inside (foreign object) but found nothing. By this time it's dark and time to head home...with a malfunctioning weapon. Absolutely nothing worse.

The rifle has maybe 200 rounds through her and never a problem.

Appreciate any comments!

The rifle doesn't have their two stage match trigger in it, does it? Check the adjustment screws if it does; I don't remember which does what exactly, but one too far in or out could cause the safety to hang up. Check and make sure the allen screw in the pistol grip is tight, too.

"Trigger won't pull, safety lever won't move."

Next time that happens open it up and see if the hammer is cocked, AR's won't go on safe if the hammer isn't cocked. Pop the rear takedown pin and pivot the upper receiver to see if the hammer is to the rear, if it isn't then you need to figure out why not.

Thanks for the comments. I'll be checking as you suggested.

The Bushmaster is stock, no mods. I'll make time to look at it this evening.

Take another look for debris as well - a fired primer that pops out of the case can easily end up in the fire control group and it can create all kinds of unusual symptoms that appear intermittently. It can also be difficult to see given its size and ability to wedge under parts.

Try shaking the lower around and listening for it or shaking it upside down during cleaning to see if you can get anything to fall out.
