There is a YouTube video. Believe it's by down east gunworks. Dis and reassembly.
There is one tiny part on the gas block that is tricky. The rear plate that the buttstock bolt fastens to is a PITA. Not really necessary to deal with the buttstock. Bolt, trigger group, follower comes out easy. All that is necessary.
I am no where near mechanical or a gunsmith. Nothing goes sproing, easy peasy. Scale of 1-10.....2.
