RRA Lower, standard safety switch.

Problem - Switch has a good postive engagement in the "safe" postition. When moved to the "Fire" postion it locks into place and will not return to "safe".

I am using the (brass?) detent with a flat base on one end and a coned end at the other. The coned end is what engages the safety selector switch. The spring goes the the flat base. (I assume this is the correct set up)

The hole if you will where the detent sits when it is locked into the "fire" postition seems to be deeper and not as beveled as the "safe" position.

Should I take a cone shaped stone on a dremel and hit the "fire" hole?

Thoughts?

Are there any tricks to installing the safety?

Thanks

You may want to try and dull the sharp point on the selector detent first.  That's what I usually do when I run into this problem.

On my AR the selector will only move to the safe position when the hammer is cocked.  When you try to move the selector to safe is the hammer cocked or is the hammer down?

It also helped it quite a bit when I put some lubricating grease in the slot of the selector.

Always remove metal from the cheapest part first.

Congratulations. You now have an AR safety that works just like all the others in the world[:D]

Seriously, that's how you can tell if the piece is in fact cocked or not; in case you forgot. If the safety engages, it's cocked.

If it's getting stuck in safe you could try to clip a little off the detent spring.

I had to do this with my fulton armory predator2 grip, I put the cut end into the pistol grip so the detent still sits on the flat end.
