I modify mags and drums for $10.00ea. Weld and re mill incorrect mags for $18.00ea. I'll need your mag well adapter to fit the mags correctly. I put a bullet in the mag and I mill the UZI mag to the correct dimension. All dimensions were derived from a Colt 32 round mag on a digital optical comparitor. Setting the origin for milling on the bullet insures the correct height. Some 40's have strange mag lips and this method allows me to not have to fix the lips. Mags converted to high and the rounds in the mag can cause empties to get caught in the upper upon ejection (the rounds in the mag actually eject the spent round prior to the ejector). To low and some rounds don't get stripped from the mag. (or usually the last round screws up) Each modified mag is checked on a 10:1 digital optical comparitor. 1 week max turn around
