So is it just taking off the screws and pulling it off? Is manhandling mandatory?
New so don't hit me too hard.
Remove the screws and the buttstock pulls out of the tang of the receiver.
However, some buttstocks (particularly wooden ones), can be REALLY tight and provide a formidable challenge to remove. Should you encounter this, give a check back. There's a few ways to remove the end of a stubborn buttstock from the receiver.
Make sure you have BOTH screws out.
Some are very tight, and some age almost "glued" in the receiver by excess stock finish.
An easy removal method that doesn't involve prying and damaging things, is to bump the top side of the butt on a carpeted floor. Turn over and bump the bottom of the butt, repeat until the stock loosens and begins to come out.
Another method is to use the heel of your hand to bump the top of the butt stock in a rearward movement, turn over and bump the bottom in a rearward movement. If it's really tight, wrap a towel around the butt and use a rubber mallet.
Some people insert a large diameter metal. plastic, or wood drift into the receiver and use a hammer to drive the stock out.
Others use a large screwdriver to pry it out.
The first method can beat up the stock socket, the second can bend the receiver.
I have two Romy G kit builds. My stocks were tighter than a bulls ass. I wanted to put side folders on them. To get the stocks out, I had to beat the hell out of them with a huge rubber mallet. Ruined the mallet, but got the stocks out. If you have a nice finish on your stock, wrap it with blue painters tape before you start beating it.
On Romy's with the solid rear trunion, I put a cheap screwdiver in the front edge of the hole, where you should be able to just barely squeeze it in, then pry it back.
On "open" Bulgarian trunions, I use a plastic tipped air hammer on a long a shank to smack the inside face of the stock tang - the vibration drives it right out.
On particularly tough stocks, I drag out the "tool"
Nice! So many times I wish I would've had one of those...
