fire selector.. limited movement

[geedavell]

I don't know a whole lot about AR's so I thought i'd hit you guys up. A coworker is building his first AR. he put it all together, he's able to pull the trigger in the FIRE position but the select lever will not rotate all the way to the safe mode. I'm assuming the holes were not drilled in the correct spots? can he turn down the center relieved portion of the control lever? if so, how much?

No, there is a flat that indexes around to allow fire. If you turn down the center enough to fire, it would fire at any position.

Compare selector to another and replace (its cheap) if its out of spec.

Will it engage if the hammer is back? My spikes will not go into safe unless the hammer is cocked.

He doesn't want it to fire in the SAFE mode but the lever won't turn to the safe mode. It binds up before it turns 90 degress

I'll ask him to try it that way

That's what I was thinking also.

It's not supposed to go into the SAFE position from FIRE when the hammer is down.

If I'm understanding correctly, your buddy has the selector in the FIRE position and pulls the trigger. The hammer drops and he then tries to push the selector into the SAFE position. The selector binds up about half way and will not go into SAFE. If that is the case, it's working properly.

Oh! The turning down/modify had me confused. Also never stated hammer recocked/ not cocked.

OK, be sure its unloaded then charge the rifle then try the selector. It should click back and forth between safe and fire. Pull the trigger, it should fire. It will not go to safe unless its cocked. Normal.

Sounds like OP needs to learn about and how to perform a basic function check.

Cocked or Uncocked the selector switch will not go onto SAFETY

Did they make sure the pointy end of the safety detent went in first? Otherwise the safety will get hung up on the flat part of the detent.

Also could be using the wrong detent, need to use the one that is pointy on one end, flat on the other. Also, could be using the wrong spring. Id start there before trimming or filing it down any.

That would be my guess.
