Excellent fit and finish, with a bonus! - Mesa Tactical LEO Gen II Tele Collapsible Shotgun Stock Adapter

I am really glad that I waited to buy the Mesa Tactical LEO Gen II (Mossberg), because the Gen II has a cut-out for the slide / action bar release. One of the big arguments against pistol grip stock for the Mossberg 500 series has always been that the grip impeded usage of the action bar lock release.
Well, this just solved that problem completely.
Tilt the shotgun slightly to *easily* and positively engage that release!
Fit and finish on the LEO unit is excellent, and I had zero problems fitting it (100% drop-in) on a 590a1.
I have went through several stock variations on this Mossberg, including the highly regarded SGA, and this is by far my favorite set-up.
It's superb for those with shorter arms and fingers!
