Hey guys! I am new here and I just picked up my ACR today. As always with my new toys I like to dissasemble and reassemble them so I can learn in case something broke. Well something did break! or could have been broken! my safety mechanism in the trigger group

I tried to put the safety mechanism back in and the spring goes in the groove (is it supposed to go into the circle?) when I pull the tab up the spring will always fall out of the groove. I tried to bend the spring more inwards and I played with it for over an hour. Can you guys help me out so see what my probvlem is?

Just workin off memory, but it looks like the bottom lip of the safety detent where the spring goes, (top in your 2nd picture) is gone. If thats the case, you will need a new part.

I may be wrong, just working off memory at the moment, I'm at work, rifle at home. I'm sure someone will chime up with a better answer.

The link indicates the video has been removed. So what's the fix?

I think he bent the end of the spring so that it would catch on the inside of the housing...but I'm not 100% sure. See what others have to say

mine is away at bushmaster for the moment so i cant reverse engineer his photos to well from memory...man, i wonder why that guy deleted his vid a few days after i put a link to it...? whatever
...yea losman, the spring is definitely supposed to go into the groove that cjt50 said looks a little mangled...if thats the case thats why it won't stay in when you pull up on it...

Well, I'm having a similar issue; when I went to remove the safety/selector in order to pull out the trigger group, the end of the hammer spring slipped out of its notch, rounding off the corner and putting a big gouge in the plastic. Now the end of the spring won't stay in place, which means insufficient pressure is placed on the lever, allowing the selector to rotate freely when the hammer is uncocked.

I tried to rebuild the corner of the notch with JB Weld; it didn't hold. So I sent an Email to Bushmaster Customer Service to inquire about obtaining a replacement lever; we'll see what they say. I'd rather not send the gun in, as it is brand-spanking-new and there's nothing else wrong with it.

Sucks that a $1600+ rifle can be flatlined by the failure of a $.50 plastic part.

The part seems fairly straightforward. I bet some place that does stampings could replicate it in metal.

that's what i was thinking DSM...i'd like to do that with the safety bottle opener and the selector...then it would be a tank....i've been wanting to buy a mini-mill/lathe for awhile just for junk like this...some fairly good ones with mill/lathe combo's are just 1000$....with a 2 or 3ft working surface...just saying.....hahaaah

Johnny, just a thought-- if you're going that far, is it possible to replace the safety selector with a 45 degree selector. Not sure if it's even possible, but it'd be worth while.

And if you're looking to stamp out a new retainer plate in your trigger pack, why not modify it just a little to allow for an easier trigger job. Just a thought.

Yes, you could. RobArm did it with the XCR and there's one manufacturer (that I know of) making them for an AR. It comes down to milling the detent stops in the appropriate place and of course allowing clearance for the trigger tail and disconnector.

+1 , FNH SCAR has a 45 degree throw as well.

Just a matter of moving the flat to a different position to allow the tail of trigger to move. I'm sure you would have to start with a clean safety since the original was cut at the 90degree point. Im sure for semi-auto fire it just a matter where the flat on the selector is to allow the trigger to move. They probably could have made the throw any length they wanted.

 

[shooter521]

I would be first in line to buy a metal 45-deg. selector and retainer assembly...

In other news, my Email to BM has gone unanswered, and nobody's home at their customer service line. Guess the move is officially underway; looks like my gun is going to be down for awhile.

Might have to take a crack at this one. I've got some scrap aluminum rods I could use. Another project to get sidetracked on.
