Hey guys, I have a rock river lower and the selector detent pin is stuck in its hole and has also caused the selector switch to s stuck in the fire position. I removed the grip and the the spring, but the pin will not come out. The only thing I can think to do is to get a drill bit that fits the hole perfectly (or alittle smaller then the hole) and to drill out the selector pin and replace it with a new pin. Is this a good approach or is there something else I can/should do?

Thanks

Christian

Usually a stuck detent will drop out if you wiggle the selector lever enough. Light taps with a no mar may be necessary to get the detent started.

[b]Just to double check, sometimes we forget the simple things.[/b] The action has to be cocked before the selector will move to the SAFE position, if it isn't cocked it will not move to SAFE.

That true, it never entered my mind.

The hole for the safety detent has two diameters, this sets how far the detent will go into the safety selector. Do not drill this part out. I agree with Wingman26 most forget that the hammer has to be cocked so the safety selector can move to the safe position.

As an armorer here is my suggestion, separate upper from your lower. Remove the grip and spring, then turn the lower upside down and take some 3 in 1 oil and drip it into the hole. Let it set for a few days and then attempt to move the selector, this should free it up. When I build any AR-15 I use Brownells action lube on all pins and selectors, springs etc.

I oiled it up yesterday and then I drilled it out and then I replaced it with a slightly smaller pin. It works great now, thanks for all of the replies! :D

that's strange i have a RR lower and have the same problem, just haven't posted it.   i was soaking mine upside down to see if it would loosen up and the detent fall out.

Mine was in so tight that I don't think it would have ever come out on its own. But it would have been much either if it came out with oil alone.

I had to drill mine out a bit to even fit that detent. This was also a RRA lower.
