i had a very bad experience with a new fast gun seat. Sent it back 3 times, it would no latch and they refused any further work.
I had to rip out the latch, epoxy the hole over and reinstall with the latch from a different seat, long screws and 1/2 inch of washers to space the latch up..
Still loosens, requiring occasional gentle tightening.
Great seat, but I'll never buy another Corbin product.
