MDT 7 PRC 3-ROUND POLYMER AICS MAGAZINE – CIP LONG ACTION
Purpose-Built for 7 PRC. Compact for the Field.
The MDT 109671-BLK is a dedicated 3-round polymer AICS-pattern magazine designed around 7 PRC feeding geometry. It supports cartridges up to approximately 3.815″ OAL in rifles and chassis built for the CIP 3.850″ long-action magazine standard, with a low profile that carries well on a hunting rifle.
The 7 PRC has quickly become a go-to cartridge for long-range hunting and precision builds, pairing modern high-BC bullets with full-length long-action systems. It deserves a magazine built for it, not a generic long-action body with a different label. MDT designed the 109671-BLK specifically around 7 PRC, so feeding is matched to the cartridge rather than borrowed from another family. Use it for: 7 PRC hunting rifles, long-range field builds and any AICS-pattern rifle where a full-height competition magazine isn't necessary.
A Lower Profile for Hunting Rifles.
Three rounds keep the magazine compact under the stock. That means a rifle that's easier to carry over rough terrain, shoots cleanly off a pack and won't have a long magazine fighting your support in field positions, while still giving you detachable-magazine convenience.
Important Fitment.
This magazine requires a rifle, chassis or bottom metal built to accept CIP 3.850″ long-action AICS-pattern magazines. Not every long-action AICS system uses the same magazine length, so confirm your chassis and action before ordering. It is designed specifically for 7 PRC and should not be assumed compatible with other long-action or magnum cartridges because of similar case size.
