They are parkerized steel mags that outlast the zytel plastic mags. We cannot ship prohibited magazines to out of state addresses. If a 10-round mag is not available we will remove the hi-cap magazine from the shipment. Each mag is disassembled, feedlips are machined evenly, front of the feedlips are cut back similar to a zytel for fit, deburred on the inside, the followers are checked for smooth movement, each spring is inspected and oiled. PLEASE NOTE: If you live in a magazine restricted state we remove the hi-cap mag and will be glad to substitute with a 10-round mag IF AVAILABLE. They are not the cheap imitations but high quality mags, matched to fit only the Mac-10 9mm Single Feed Bolt.
