the barrel was a remington fully rifled barrel but it was a real sloppy fit in the receiver. it was hard to keep three slugs on a redfield target at 100 yards. after the epoxy it became a consistent 3 inch grouper at 100 with the slugs it liked.
release agent-- it is god awfull expensive but it always works, never had a problem with it-- it is the spray stuff that brownells sells.
