Save time and money by making your magazines legal. 

NOTE: These are recommended for gunsmiths and hobbyists who don't mind experimenting with the length to get the fit they want. We do offer these as an option for some magazines already precut.  Now you have an option if we do not have a limiter available for your specific magazine with the recent law changes. If they don't work out for you just send them back for a refund or exchange.
