Currently, I am a Certified NRA Firearms instructor and have owned over 31 different firearms of which 3 have been AR-15s. I have replaced quite a few parts on my previous 2 ARs, including installing an ambi safety on one about 3 years ago. Had no problem at all. Now to my current problem. My current AR is an M&P Tactical.
I am at a total loss to figure out how to remove the existing safety on my current AR and install an ambi. I have removed the grip, along with the spring and detent and the weapon is cocked. However, the safety will not come out of the receiver. I even tried to use a punch to "force" it out and it only moved out about an eighth of an inch. I know that under the disassembly actions that I have described, the safety simply should have fallen out of the receiver, but no go.
Can anyone help?
