Npas for the WE416
Well, I think this is the right place to ask this, but I was wondering... I've heard a lot of stuff for GBBR's (I own a WE416) such as get an NPAS, Open or closed bolt?
Basic question is, I know mine is closed bolt (looking into Openbolt if its better, welcome to chime in opinions) and I've noticed off airsoftparts.ca that they have two NPAS kits for closed bolts and one for open. I'm not 100% sure which one to get for when my 416 is using closed bolt. Whats the difference in the two versions?
