so I got a we tech m4 (version 2) and want to put in a RA-Tech Negative Pressure Air System NPAS for WE M4 Gas Blowback Airsoft Rifle Series (Version 2). Is this advisable and are there any other mods needed in addition to this? Thanks for the help!
there's a ton of stuff you need to do to a WE M4 before you go out and shoot it. if you havent read anything about the GBBR's, id suggest looking through the massive internet for some information on them.
