Its the kit that oss uses, but you have to do the install. Its not super hard but does require some basic skill and attention to detail. The "lite system 3" actually looks like a better kit than what I used, though its about $100 more. If youre wanting to go the ring swap route i'd suggest them.
This first shot is a little underexposed, but you get the idea. Just wanted to prove that I did do the install, and that it is possible for you to do it at home, however I take no responsibility if you screw it up
