PERAZZI MX8 TUNE-UP To keep your Perazzi MX8 style shotgun in top shape there are a few service springs that need to be replaced on an annual basis. The top lever spring in these shotguns goes to full compression when the breech is opened. This is a stressful condition for any spring to be subjected to, and over a period of time the spring degrades. The top lever spring controls how tightly the locking lug engages the barrels when the breach is closed. A worn and weak top lever spring allows movement between the locking lug and the barrels and is the first turn down the road to a new locking bolt. It is much better (and a lot less expensive) to stay on top of the condition of the top lever spring. The ejector springs in these shotguns are a little too strong and have a tendency to throw the hulls a little harder than most people like. They also stress the ejectors unnecessarily. We offer a spring service kit for this shotgun that includes both size top lever springs .150 old style and .170 new style, a set of reduced power ejector springs and two new firing pin springs. All the springs are made of top quality chrome silicon wire and are preset for a long life. Follow the link below. J&P Custom Products, LLC | Gun Springs Manufacturing
