  • Wait, does the CQB model need its own special hop up chamber?

  • @ratech5915 do u have to cock it back everytime u put a new mag in?

  • why is the western arms brand so expensive?

  • I know this sounds really pathetic.

    But I cant any hopups systems in your website. lol

  • wat the heck is is the rpm!!

  • Can you do a guide or video on how to install the hopup and other parts of the WA M4. Thanks.

  • Not hard to do at all... I'm actually thinkign of making a video how to do it. I've had to fix a lot on my WA M4, and I'm about ready to make a how to on all of it...
