M-LOK Rifle Round Holder for Intermediate Calibers

This holder is designed for intermediate calibers with diameters ranging from 0.22 in. to 0.36 in. (5.6 mm to 9.1 mm). Popular calibers include .223 Remington, 5.56 NATO, 300 AAC Blackout, 350 Legend, and .357 Magnum. The precision-molded chambers provide secure retention while allowing smooth extraction when you need the rounds. Each chamber tapers slightly to accommodate the full diameter range, ensuring your specific cartridges will fit snugly without rattling during movement or recoil.

No, the low-profile design is specifically engineered to maintain full scope clearance on most rifle configurations. The holder sits close to the M-LOK rail and extends minimally outward, allowing standard scope rings and bases to clear without contact. The streamlined profile also preserves space for other accessories like bipods, lights, or foregrips. However, we recommend checking your specific setup since some ultra-low scope mounts or unique configurations might require verification. The compact footprint typically works well on both top and side rail positions.

The M-LOK mounting system uses the industry-standard connection that's proven reliable across countless firearm applications. Our reinforced mounting points distribute stress evenly across multiple contact surfaces, preventing loosening under recoil. The Nylon 12 construction flexes slightly to absorb shock while maintaining structural integrity. Proper installation with the included hardware creates a rock-solid connection that won't shift during firing. Many users report excellent performance on everything from .223 to larger intermediate calibers without any mounting issues after thousands of rounds.

Absolutely. The open-top design allows you to extract rounds with a simple upward motion without breaking your shooting stance or losing sight picture. The chambers are positioned for natural finger access, and the smooth extraction doesn't require twisting or manipulation. This makes it ideal for follow-up shots on game or rapid transitions during shooting sports. Unlike closed pouches or pockets that require multiple steps, you can grab a round and reload in one fluid motion while staying focused on your target.

At just 0.21 oz (6 g), this carrier adds negligible weight to your rifle setup. The M-LOK positioning keeps the added mass close to the rifle's centerline, minimizing any effect on balance or swing dynamics. Most shooters don't notice any handling difference once installed, especially considering you're carrying three extra rounds that would otherwise add weight in pockets or a separate pouch. The strategic placement actually centralizes the weight of your ammunition rather than distributing it around your body, which many hunters prefer for improved rifle balance during extended carry.
