  • Quit losing detents and detent springs

    Saw an interesting mod for the AR15. The only thing holding the detent and spring for the rear takedown pin is the receiver end plate. When removing the plate, it is easy to launch and lose the spring. When reassembling, it can be quirky to get the spring in and keep it there when replacing the plate.

    You tap the rear of the hole for the detent with a 4-40 tap; drilling isn't necessary, just tap it. Clean up the threads. Snip 1/8" off the detent spring. Put the detent and spring in, then top it off with a 4-40 set screw, tighten down flush.

    Pretty good idea, I think. I'm gonna order a 4-40 tap and try it out.

    Shortly before World War I, the German Kaiser was the guest of the Swiss government to observe military maneuvers. The Kaiser asked a Swiss militiaman: "You are 500,000 and you shoot well, but if we attack with 1,000,000 men what will you do?" The soldier replied: "We will shoot twice and go home."

        I seem to remember a receiver manufacturer who already does this with their receivers (Aero Precision?). FWIW.

          Aero does do that, it's the next best thing to installing a magnetic ceiling
