  1. Damien M.

    I’ve been using this mag on my TM G17 for about a month now, and hands down this is the most entertaining thing I’ve used in a long time. I play on a relatively low populated field (Average around 10 players) and very rarely do I see HPA being used, but I’ve got both HPA in a compact form. My TM is built so it has plenty of range and performs great alone, but with it being adjustable with HPA and now, having what feels like unlimited ammo, I’ve hit the new level of Speedyboi Airsoft. Originally I got this as a joke, but it has since replaced all my other guns (Nov SSG, E&L AK, Etc) and is my new primary, just because of how much fun it is to use only a pistol.

    Feeds Great
    Haven’t had to replace the battery yet
    Holds plenty of ammo
    No longer need to carry spare mags on my plate carrier
    It looks sick
    Seems to be durable (I’ve had a few nasty falls-It’s muddy here-and It hasn’t broke on me yet.)

    Rattles because it’s a high cap (I don’t care, I’m Forrest Gump and never stop running while using it)
    Has Velcro covering the BB port (I play out doors so I’m semi worried about this getting torn open and allowing derbies to get in

    Still give it a 5/5 because I haven’t run into any real issues with it.
