MDT M-LOK Multi-Caliber Spare Round Holder – 2 Rounds

MDT M-LOK Multi-Caliber Spare Round Holder

The MDT M-LOK Multi-Caliber Spare Round Holder provides a convenient way to keep two additional rounds readily available on the side of your rifle. Designed for shooters who want quick access to spare ammunition, this holder provides additional onboard storage without requiring another magazine.

Its multi-caliber design supports a wide range of common rifle cartridges. An adjustable spacer system, combined with small and large caliber polymer bodies, allows the holder to accommodate different cartridge sizes while maintaining a secure fit.

Keep Two Spare Rounds Ready

Running short on ammunition during a stage or needing an additional round during a shooting session can be inconvenient. The MDT Spare Round Holder provides storage for two additional rounds directly on the rifle.

This compact solution is particularly useful when carrying a spare magazine is unnecessary or when having a couple of additional rounds immediately available is beneficial.

Multi-Caliber Compatibility

The MDT M-LOK Multi-Caliber Spare Round Holder is designed to accommodate a broad range of cartridge sizes, including:

• .223
• 300 AAC
• .224 Valkyrie
• 7.62×39
• 6.5 Grendel
• .308
• 6.5 Creedmoor
• 450 Bushmaster
• 7mm
• 300 WM
• 300 PRC
• 6.5 PRC
• And more

The system includes small and large caliber polymer bodies along with an adjustable spacer system for greater compatibility across different cartridges.

Adjustable Spacer System

The spacer system uses Mil-Spec washers and O-rings to fine-tune the fit around the selected cartridge. This allows the holder to be adjusted for a secure fit across its broad range of supported calibers.

The combination of interchangeable body sizes and adjustable spacers makes the holder a versatile solution for multi-caliber applications.

M-LOK and ACC Chassis Mounting

The spare round holder can be mounted using M-LOK slots or the accessory holes located on the side of compatible MDT ACC chassis systems.

Its reversible design also allows installation on either the left or right side of the chassis, giving shooters flexibility when configuring their rifle.

Staggered Design for Additional Clearance

The MDT Spare Round Holder uses a staggered design to provide greater clearance around the ejection port. This helps keep the spare rounds positioned alongside the chassis while allowing space around the rifle’s ejection area.

Durable Polymer Construction

The holder features a glass-filled polypropylene polymer body, providing a lightweight and durable construction suitable for use as a rifle-mounted accessory.

Compatibility
