The hop-up chamber is where backspin gets applied to a BB, and how evenly it does that decides your range and grouping. MAXX machine their chambers from aluminium to far tighter tolerances than a typical moulded part, holding the bucking and barrel in consistent alignment shot after shot. They also make the feed tubes and small fittings that surround the chamber, so a whole feed path can be upgraded together.
What we stock
We carry the M4W and M4P PRO hop-up chambers for the MTW, advanced CNC feed tubes and magazine releases.
