FOE SALE is a MAC M-10 45 Auto to 9mm conversion kit with some extra parts.
The kit includes 2 bolts. One is the original style bolt and the other is the newer style bolt. Both bolts are for double-feed mags.
Also included but not shown is a new extractor and retaining pin for the original style bolt.
The metal magwell insert has been modified (butchered) by me and probably can't be used. You will need to get a new one. I have seen them for around $50. You will also need to get a new buffer. Also included is a mag catch that might or might not work with your lower and mags.
The price is $400 + shipping cost.
