Hi all, I am a new owner of the long awaited marauder conversion kit for the Ruger 10-22. I don't know how many people have had issues with the magazine, but I couldn't find any threads that addressed the issue. Apparently this problem is more common than I thought but it looks like only people that got one of the first kits will have the problem. Anyway, after searching various forums I finally called blacksun tactical (who I purchased the kit from) to see if they could fix the problem. They contacted Promag and put up a page on their website that listed the instructions for how to fix the issue. They also had Promag send me a new magazine just in case it didn't work, which I thought was pretty nice since I now have 2 mags! Anyway, the page has a video that goes through how to take apart the magazine in addition to the following instructions that I copied from the site:

1. Make sure magazine is unloaded.
2. Remove internal components.
3. Remove replaceable feedlips.
4. Try to fit a .22LR cartridge through the slot in the top of the magazine body. It will drag slightly at the front and the rear of the shell.
5. Use a small file or hobby knife to gently scrape a very tiny amount of material from both sides of the opening.
6. Test that the cartridge now slips through with no resistance whatsoever. If it still makes contact, repeat #5.
7. Reassemble magazine making sure the top of the spring has the last coil towards the front of the magazine.
8. Magazine will now function perfectly.
I hope this helps someone else who got one of the first kits. Other than the magazine, the kit is awesome!
