Anyone played with adapting larger mags? I only have the one five rounder that came with my upper. They want $49.00/each for those things, so i'm thinking about adapting some of my .223 mags. I only brought a couple of 10 rounders with me to NY as just about everything, (except paying taxes), is illegal here.
I haven't had much luck getting the ten rounders to feed the last two cartridges, (loaded with five .450 Bs, that makes them 3 rounders at best).
Anyone had luck adapting .223 mags?
