Engineered for the Wolverine MTW
The PTS EPM-MTW M4 magazine is a collaboration between PTS and Wolverine Airsoft, built specifically for the Wolverine MTW and Heretic Labs Article series HPA rifles with an M4 or M16 magwell. That focused design means it drops in and works exactly as it should, with full support for the MTW-spec empty magazine detection feature.
120 rounds, mid-cap discipline
With an approximate 120-round capacity, this is a mid-cap magazine that rewards good trigger discipline. You get enough BBs for fast-paced CQB and MilSim scenarios without the extra weight of a hi-cap, keeping your loadout light and your reloads realistic.
Quiet, reliable feeding
Forget winding wheels and rattling BBs. The EPM-MTW uses a strong internal spring to feed reliably with no winding required and no rattle as you move, so you stay quiet on the approach and confident that every shot will feed.
Tough Zytel build
Constructed from high-quality DuPont Zytel polymer, the magazine is made to take the knocks of regular skirmish use while staying light at around 176g. It is a genuine, purpose-built spare or spare-set addition for any MTW owner. Note it does not fit the MTW-9 or MTW-308. See our airsoft magazines range for more options.
