I have the same hang up issue. Its almost like bolt hold back. But a slight touch and it slams home. I don't see what you could do here that wouldn't be taking serious material off of the bolt. Not worth it.
You can switch to a bolt that has the lightening cuts in it. If yours doesn't already. Mine does. Still hangs up though.
As far as the break, what break do you have? All are not created equal.
IMO if it is not one of these
two. You are missing out. I cannot explain with words what a difference it made for me.
No more getting pounded. No more muzzle rise. In fact, the faster you shoot, the better it seems to stabilize the gun. And it doesn't kill you with noise or blow back either. If you want follow up shots to be thoughtless. This is the way to go. Huge improvement. Worth double the money.
The buffers work. I have a polymer stock on mine, and I don't know if wood transmits those ringing receiver hits into your face like the hard polymer does. But I would guess it does. If you are in and tight, especially prone. And you would like to stop being the buffer that soaks up the beating. Buy the buffer. Controlability is improved if its not slamming back into the rear trunion. That heavy hit has the side effect of throwing its momentum back, tipping the muzzle up. Its cheap. Buy it.

I don't know if they are all equal. But they should not be rubber. They should be polyurethane. Like aftermarket suspension bushings. Somewhere around the look and feel of energy suspension's with the same durometer.
In all, those were the best 2 things I did for the gun that weren't just me going out and shooting it.
