Hi! and thanking in advance to anyone who can assist me. I have a lot of questions.. here we go! :)
1) I have an aftermarket gas puck (pic attached) Which way would it be installed? the flat slide towards the piston or the side with the grooves? and is this a good puck or should just stick with original?
2) Setting 2 on gas plus is for low brass, correct? If i were to shoot on setting 2 with high brass, what would happen? just more recoil with greater reliability of cycling? or should i not do this at all?
3) Any drums that you would recommend?
4) what parts should I oil and wha
