View Full Version : Mossberg Silver Reserve O/U question

April 9, 2005, 05:48 PM
I finally shot my NIB Mossberg Silver Reserve O/U shot awesome. This is my first O/U. I cleaned it when I got home after about 25 rounds and there was black almost like peeling inside both barrels when cleaning. Just wondering if this is normal it did not do it on my Mossberg Pump. After getting all the pieces out after swabbing for a while it looks smoother could it have been a film in the barrels??
