Answer is in below posts, but be warned, it's hard to explain without sounding dirty.
I have a 20 ga. Summit Sporting that started getting harder to take down at the end of last season. Got her out for the first time this year today, and almost c/n break it down after shooting b/c I c/n take off the forearm w/o great effort, b/c the end nub of the plunger/release which protrudes from the end of the schnabel had somehow worked it's way down and is only now about flush with the wood. I tried to take the metal assy off and out of the wood (couldn't be that
hard, now could it?) after determining (I think) that none of the accessible screws adjust the plunger, but never could get the thing loose.
There are two small torx screws that fit flush w/the receiver, and I took those out, along w/the flathead screw and the 1.5m hex screw in the middle of the assy, but that alone was insufficient, and obviously I wasn't gonna do anything to hurt it.
Is there some "trick" here I'm missing that does it? Some other way to adjust the plunger/release? If not I'll just be sending it in for its first pit stop a little earlier than planned and have CG handle it while it's there. I just get the feeling this is something that would only take their 'smith about 5 min. to fix, using only a bit driver, bits, and possibly blue lock-tite.
Anyone else taken the thing down?
