Just received my new issue of American Rifleman and read their article on the new Inland Mfg M1 Carbine. It seems they ran into the same problem I had with failure to cycle and they resolved the issue with using different magazines. I've just ordered a couple of Korean made 15 round mags and I'll report back after I get to try these out. It was a good article and I'm excited to see if this works. I really like the looks and feel of this carbine and I hope to get good results with these Korean magazines.
