I took a dead blow hammer and a wooden dowl and tapped it out from inside the receiver.
What furniture did you get? I got some Russian surplus blonde 74 wood on my 107R.
Eta: Oh now I see you can unscrew the tang screws? Stop being weak. But also dont strip them out.
I decided to grip the screw driver with a pipe wrench and that did the trick.
I got some walnut, it's looking good so far.
I need to whack the stock out with a rubber mallet (from what I've seen online) but I have to wait until tomorrow.
Also my ports in the side of the foregrip aren't aligned perfectly. Is this common, or should I mess around with it some more. It seems like a snug fit.
