PRG – M-LOK External Weight

PRG – M-LOK External Weight

Designed and manufactured in Austria by Performance Rifle GmbH

We are proud to present the PRG – M-LOK External Weight, a high-performance weighting solution developed and manufactured entirely in Austria. With this product, we have achieved what was previously considered impossible: the highest weight-to-volume ratio currently available on the market. Through innovative design and advanced manufacturing methods, we created a compact component that delivers maximum mass without wasting valuable mounting space.

Like many PRG products, the M-LOK External Weight offers far more than a single function. It combines three essential roles in one compact unit: a freely positionable weight for perfect rifle balance, a stable hand grip for the support hand, and an integrated support surface that functions similarly to a barricade or bag rider wing—without occupying excessive space needed for additional accessories. Both the top and bottom surfaces feature a specially designed texture pattern to ensure maximum grip on your shooting bag as well as secure control with your support hand.

Installation is fast, precise, and user-friendly. The weight is mounted using two M-LOK screws and can be installed or repositioned by any shooter in minutes. This makes the PRG – M-LOK External Weight universally compatible with any rifle equipped with an M-LOK interface and ideal for shooters who need flexibility during training or competition.

The entire component is 3D printed from corrosion-resistant stainless steel and subsequently filled with lead to achieve its exceptional mass. This construction not only maximizes weight but also helps reduce vibrations within the chassis, resulting in a calmer rifle during the firing sequence and improved recoil management.

Experienced competitive shooters know that additional weight on the rifle is essential. Stability during the shot, the ability to spot impacts, and achieving optimal balance can only be accomplished through a well-designed weighting system. The PRG – M-LOK External Weight delivers perfect weight distribution while simultaneously providing a functional bag support surface and an ergonomic thumb rest—three advantages in one highly efficient component.

Thanks to our advanced manufacturing process and carefully engineered design, we succeeded in creating the heaviest and most cost-effective external weight on the market. No stacking of multiple weights, no unnecessary consumption of valuable M-LOK slots, and no compromises. No other product offers this amount of weight and functional benefit in such a compact footprint.

All components are made from fully corrosion-resistant stainless steel and can be easily cleaned using an ultrasonic bath or standard commercial cleaning agents, ensuring long-term durability and minimal maintenance.

Improve your shooting performance with the PRG – M-LOK External Weight by achieving greater stability, a lower center of gravity, and perfectly balanced rifle handling. For further optimization, we recommend combining it with our PRG – Internal Weight to fine-tune your rifle’s balance even further.
