The bolt action will be getting full of residue from the bullet recoil. You have to take the barrel off to get to the action, which slides right out. About every 500-1000 bullets fired. Be careful when removing the barrel ( do not twist too much) because the ejector sits in a slot in the barrel twisting can either bend it or break it. But good shooting, they are good little guns. I used one for a few years for varmints until the Mossy 151 made an appearance.
