$5.00If you own these magazines, you know that over time, the lips on the plastic magazine wear away and open up causing bullets to double feed and jam your gun. Feedlip kits will return your Zytels to as new performance and I doubt you will wear them out. Also, installation of these feedlips will allow you to use .380 ACP ammunition in it for use with the M11-A1. Feedlips are made of .008" thick tempered stainless steel and include detailed instructions for installation. ***FREE Shipping*** Includes one left and right side feedlip, enough to repair one magazine.
