New 522 SD LW owner here. I broke it down to check the screws and put new HK pins in. (I was going to do the screw upgrade and a few of the 5 retrofit parts, but I cant find the locktite.)
I must have not re-installed things correctly. The action is frozen, and I cant get it broken back apart again.
I cant get the "breech fixing part" (diagram part 48) because I have diagram part 90 (spring guides?) rearward and not move-able.
I have tried taking it off safe and cycling the action/firing trigger (with a mag in) and cant get the part 90 spring guides forward to remove the breech fixing part.
Can anyone give me some directions/options to disassemble and reassemble correctly?
Nevermind! Got it!
