There’s a very good article in the new issue of Combat Arms on the new KMR uppers. It included a picture of the stripped ELW barrels as well. It stated a 0.625 oz. weight savings on a 14.5 barrel. An interesting note, it also discussed the Mod1 comp and described it as having an expansion chamber that improved reliability of the 14.5 midlength barrel. I had not heard that before. Overall, it’s a good article. The issue had some of the best written articles I’ve seen in a print magazine in a long time.
