It's been a great upgrade, really brings the Carbine into the 21st century. I refuse to make any permanent modifications to any of my surplus firearms. I also installed the Unimak rail (Christmas present from my wife) and mounted a Romeo5 red dot. The other 20% was my astigmatism which makes the rear sight look like an oval instead of a circle. I followed their advice on tightening it up and group size got much better. It was too loose and the barrel did not hang as it should. My recoil plate was probably 80% of my accuracy problems. I found a great article on the CMP website about accuracy of the M1 Carbine. I know carbines are not known for great groups, but this one seemed really bad, I began to suspect the barrel was worn out or damaged by the Blue Sky import stamp. This one has been getting my attention lately. Now that I'm retired, I actually have the time to get out and shoot some of my firearms. I fired it a few times back when I got it, and it was OK, but it's mostly been in the safe. The metal parts of the Carbine look good thanks to the refinish job done by Blue Sky, but I remember the stock looked terrible when I got it, so I refinished it. It's a Korean re-import by Blue Sky, and other than the barrel and receiver, everything else is pretty mismatched. I bought this M1 back in 1990, still have the receipt, it was $139.00 through shotgun news.
