AR-15 .22lr conversion kits... Stainless steel or Carbon steel?

[Guest Jack Brickhouse]

Which is better and why?

I would say stainless would offer more corrosion resistance.

Mine are all carbon but that is because they work fine and I bought them before SS was available. If I had to buy a kit now it would, without a doubt, be stainless.

I've got SS and a pal has carbon. Not much difference. I'd say look for the deal.

I have shot the stainless CMMG. It shot flawless.

I just bought this and a spare mag for it, great deal for sure. Only had two failure to feeds with my setup.

I'd say the stainless ones will be better, but just depends on how much you want to spend. I have an older CMMG non stainless version and it's always run pretty good with cheap federal ammo and a little lube.
