Lage 22 kits are by far the most ready to run 22 kits available. He also stands behind his product 100%. It is amazing to me the reliability his kits have given the sloppy/crappy parts the macs have. The only time i have issues is after 500-600 rds when things get pretty dirty. To me, the m-11 is the way to go. They are still priced cheap, there is a growing amount of aftermarket support with the z-mags, lage uppers and other goodies, and now the sabre uppers. There is also talk that there could be a 12 gauge upper in the works!
