New AR builder

[Gary P. Nasca]

Just saw Rugers SR-556 in American Rifleman,,,nice. I'am just starting to do some checking on my first build and was looking for some input on using a piston driven cycle. I read that there are some conversion kits out there. What companies sell these and do they have a complete assembly for a new build ?
