I just picked up an M53 kit, building it SA of course (unfortunately...). I've done a few other kits but nothing this involved. I would like to do as much of it on my own as I can. I'm planning on using BRP receiver halves with an AR component FCG.

My question is: are there drawings/dimensions available for a SA bolt extension, firing pin, and modifications for the AR FCG? I've looked all over to no avail. I would like to fabricate these components myself. It's not that I can't afford them, I just enjoy making things.

I've already reverse-engineered the barrel bushing. Still need to add grooves for the guide sleeve to slide in. Planning on using the Bridgeport as a vertical shaper. Grind a tool, lock the spindle, and take many small cuts with the quill (power off of course). Anyone try that yet?

Good Luck with your build and that front area looks great.

Thanks, 42rocker! That's pretty much exactly what I need. Only thing I'm missing is firing pin dimensions, but I can probably figure them out if that's the only missing piece though.

Thanks again!

1st As we are both doing this on Christmas.
MERRY CHRISTMAS

2nd Good Luck on making a firing pin. I have always bought mine from Brian at brpguns.com
at a cost of $30.00 I'm not going to try to make one that length and that thin on my lathe.
