Piston Kits

[oneof79]

If I decide to go with a piston kit for my 10" AR in 5.56, which manufacturer would I go with? I have heard that Adams Arms kits are good but don't know for sure. Any advice?

I'm not sure if PWS makes one for a 10" gun or not but they have a great design.
Check them out.

I found this on their website;

"PWS discontinued the retro-fit system due to the overwhelming amount of inferior and non-mil spec components made available to the market in 2009. We have since developed the MK1 piston driven upper and rifles and will produce and market those from this point forward."
