lol well it's more intricate parts but you can always swap back. Idk saw it on Rainier Arms Facebook page and was just wondering. What piston system are you running?
I run the Adams Arms mid length set up and have been more than happy. The only issue i have with it is it did not cycle steel ammo reliably. Which I hear will clear up after break in but being a reloader I hate using steel as it ends up costing me more because of the lack of reloadable brass.
