Fal FCG, striker/fp, and bolt extension test.
Posted: Mon Oct 03, 2005 5:38 pm
I took the day off planing on jury duty but got out of it so gun time for me. Last night my helpfull gun buddy welded on my bolt extension for me and got it crooked so the morning I semi- straightend the piece of square tubing I used and recut the hammer slot. a cocking bar was welded to the bolt (parallel) and then on to the FP.
I decided to follow Pirates lead with the fp hitting the wedge - it solves so many issues, while I was concerned about slam fires, I had none. I did opt for make spacers using a larger piece of dril rod rather than attempt brazing with my map torch (im out of gas). I then used a roll pin to secure the spacer. I searched thru my spring pox and came up with a glock recoil spring (one of the flat coil factory ones) and cut it down and placed a 1/2 inch spacer in front (not attached to the FP).
I also ran into trouble when the feed pin cracked as I was drilling thru it. I just ground it down and peaned it into the top of the extension for now.
Once I got reliable primer 'pops' in the garage (this required me trimming the spring length) and lengthening the rearward portion of the FP. I tried it with out the spring and got a nice slam fired primer. so back in the spring went. And off to the range.
First round bang but the hammer bound on the disconector and was locked too far down. So I fired a few more single shots - after 10 I decided the sear/disconnector was binding on the underside of the hammer. I cut 2 coils out of the little spring and the hammer did better. I fired about 20 more rounds and then had to pack up to pick up the kids. I still need to do some tuning on the sear spring. I also think things will improve if I clean up the parts and add some oil/grease.
I'll post some pics when I get a chance to take them, but Im mister mom today as my wife started back to work. Plus everything is very rough and needs some clean up before published....
the neck of the cases are getting pretty dinged up - any idea what this is from?
