Prepping CMMG Magazines

[asmurff]

I had not had time to get my Spikes ST-15 ready for shooting with the CMMG Evolution Conversion kit. After I get the magazines prepped I'll be ready to go for a range trip tomorrow.

Honestly, telling me to take a file or sandpaper to the bosses on the rear of the mags slightly freaked me out. I've finished the first one and am now ready to do the other 2. At first if I got the mag fully seated before sanding the bosses I had to use a dowel and small mallet to tap them back out, no amount of pulling was going to get it out.
