Piston kit

Kit came with no instructions.I had to locate the Addams arms website, their system is identical to the Stag system, to find installation instructions. I haven't installed the kit yet as I bought it for an upcomming build but thought I'd let people know where to find the installation instructions. Be aware this is for a carbine length system and the gas block will not fit under a handguard. I gave it 4 stars for the lack of instructions, the kit was complete and I understand that the modified carrier prevents carrier tilt, from extensive web searches while searching for the installation instructions.
