Triple Threat, Zero Noise

Spiritus Systems Rifle Magazine Insert – Triple 5.56 x .45

Designed specifically for the Micro Fight MK3, MK4, and MK5 Chassis, this triple mag insert holds three 5.56 magazines in a streamlined, low-profile format. Ditch the flaps and noisy closures—Spiritus uses quiet, form-fitting elastic to deliver fast, silent access and outstanding retention.

Whether you’re running PMAGs or USGI mags, this insert keeps your kit tight and your reloads smoother than a brass mag drop. It fits snugly in both the front and rear Micro Fight pockets—giving you options to run light or double your capacity to six mags total.

This is a must-have upgrade for anyone running a Micro Fight chest rig, turning a minimalist chassis into a serious load-bearing platform.
