Quite easy.
Trigger group stays spotless.
Bolt face and the three big lugs are easy to clean
Wipe the sides and under of the bolt carrier same for the guide rails
Piston is a little more harder to clean than the rest due to carbon deposit, nothing too complicated.
The barrel extension cleans the same way as an AR-15
I haven't checked the gas cylinder and gas tube yet.
Everything takes down very easy, the only wierdness is the firing pin that must be flipped.
Compared to my SVT-40, I like it, no 8915743 small parts to fiddle with, thank god I don't shoot corosive...
