The MDT M-LOK Spare Round Holder delivers a clean, practical way to keep two extra cartridges secured on the side of your rifle. Built from durable black polymer, it includes both small and large caliber bodies so you can tailor the fit to a wide range of popular cartridges while maintaining a low-profile footprint on your chassis.

This multi-caliber holder is ideal for precision rifle shooters, hunters, and dedicated range users who want immediate access to follow-up rounds without fumbling for ammo. The adjustable spacer system uses Mil-Spec washers and O-rings to fine-tune tension, and the reversible design lets you mount it on either side of compatible M-LOK handguards or ACC chassis accessory holes. It reflects MDT’s focus on thoughtful, shooter-friendly innovation.
