Compatible with any mag on the market. (UPGRADED VERSION 9.6.23)

Monk Customs' very own M4-adapter is called M-adapter! Use your HPA M4 mags on your Hi-capa or Glock, connecting your air-hose directly to the adapter. The carefully chosen angle enables close to the ground plays.

M-adapter is available in nylon and aluminium versions.

Monk Customs M4 adapter is created using high-grade aluminium to achieve that perfect combination of quality, balanced weight and durability.

The aluminium M-adapter is made to last, resisting wear, even with many mag changes or switching replicas.

The materials used make sure the adapter can take a beating, because you'll most certainly find yourself in tight spaces using the adapter. You'll be confident your mag keeps feeding.

Using the M-adapter means you'll keep your dexterity for your handgun. The light-weight material makes sure you'll barely notice the adapter at all.

The M-Adapter comes anodized in beautiful colors, so you can match it to your replica — what's not to love?

For added convenience, we also ship M-adapters with an ultra-light mag shell, pre-installed.
