Mine had a backwards barrel. About 2 inches in front of the chamber it tightened up to about .20 to .21 then about an inch later went out to .23. (clearly made last thing friday evening before knock off). It meant that the bullet was swaged down just after leaving the chamber and barely touched the rifling after that. Made it a 3" barrel with a 12 inch solid steel flash suppressor / front weight. Had they turned the barrel around and chambered the other end the barrel would have tightened up at the muzzle and possibly been a real tack driver.....
