undertoad 9 Posted May 19, 2012 Report Share Posted May 19, 2012 I'm working on my underfolder and can't quite see what is the function of the two notches on the vertical axis of the center hole. What are these for? Thanks! Quote Link to post Share on other sites
smartbomb 133 Posted May 19, 2012 Report Share Posted May 19, 2012 (edited) they are there to allow he folder to lock. look at the parts you have. there is a collar that has 2 pins that spring load and slip into these notches when the stock is extended eta: you will need to mimic these on the receiver. i used an 1/8" carbide cutter on my dremel to notch the receiver.

I was wondering if maybe it was meant to allow driving one of the pins out partially and then pulling that part of the shaft out og the starboard side to complete removal of the pin? I want to cut what I need to cut, but I want also to cut no more than necessary. Quote Link to post Share on other sites
CnRnut 3 Posted May 20, 2012 Report Share Posted May 20, 2012 You need to cut for them. Quote Link to post Share on other sites
undertoad 9 Posted May 20, 2012 Author Report Share Posted May 20, 2012 You need to cut for them. OK, I will. Can you explain to me their function? Quote Link to post Share on other sites
G O B 3,516 Posted May 21, 2012 Report Share Posted May 21, 2012 It's been a while since I had one apart, but IIRC the little holes are where the pins get inserted. Quote Link to post Share on other sites

Yes, that's what the holes are for. What I'm curious about is what the slots at 12 and 6 o'clock are for. Do any of you know? Quote Link to post Share on other sites

This is the truth. Well, #5 is on the left side of the weapon. The slots I'm asking about are on the right side of the weapon, so the pin in #5 could never contact the slots shown. Anybody know what the slots at 6 and 12 o'clock on the right side of the trunnion are for? I don't want to cut them if they're not needed.

FunkedOut 91 Posted May 22, 2012 Report Share Posted May 22, 2012 (edited) Look at 4 again. Picture was taken from muzzle to breach. See that pin at the left of the picture? It's on the right side of the gun when looking from breach to muzzle. Look at 5 again. Muzzle is off to the left on that picture. Thats the same pin from 4 inside the trunnion slot. eta: just checked my underfolder and receiver is not cut. The pin lives in the trunion only.

undertoad 9 Posted May 22, 2012 Author Report Share Posted May 22, 2012 OK, then. I won't cut the slots into my receiver. Thanks, all. Quote Link to post Share on other sites
