Revolutionary Optics Mounting System for AK Enthusiasts
West Virginia manufacturer JMAC Customs has unveiled its latest innovation: a precision-engineered 1913 Dust Cover Assembly specifically designed for Zastava's renowned M85 and M92 AK pistol series. This full-length Picatinny rail system represents a significant advancement in AK modernization, promising reliable zero retention for various optics and accessories.

Addressing Traditional AK Platform Limitations
The Challenge with Classic AK Design
The Kalashnikov platform has earned its legendary status through decades of proven performance, with Zastava Arms carrying forward this legacy since the Yugoslav era. While Zastava's AK variants have gained tremendous popularity in the American market—particularly as import restrictions have limited alternatives—these firearms inherit the same mounting constraints that have challenged shooters since the AK-47's inception.
Modern Solutions for Timeless Firearms
Contemporary shooters demand the ability to equip their trusted platforms with modern optics and accessories. JMAC Customs addresses this need with their engineered solution that bridges the gap between classic reliability and current tactical requirements.
Engineering Excellence in the 1913 Dust Cover Assembly
Superior Construction Methods
The new dust cover assemblies for M85 and M92 models showcase advanced manufacturing techniques. Crafted from a single piece of 7075-T6 billet aluminum, these components deliver exceptional strength and longevity that far exceeds conventional alternatives.
Innovative Locking Mechanism
The proprietary locking system sets this product apart from traditional dust covers that often suffer from alignment inconsistencies. JMAC's design ensures consistent return to zero with each opening and closing cycle, addressing one of the most significant concerns with AK optics mounting.
Patent-Pending Adjustment System
The octagonal cam adjustment hardware represents a breakthrough in secure mounting technology. This fully adjustable system maintains tight lockup even when screws may loosen during intensive use, providing vault-like security for mounted equipment.

Versatile Integration Capabilities
Comprehensive Mounting Platform
Designed to work seamlessly with JMAC's MMS Lower Mount system, this dust cover transforms the AK into a versatile platform capable of accommodating various accessories including:
- Red dot sights
- Prismatic optics
- Magnified scopes
- Magnifiers
- Laser devices
- Additional tactical accessories
No-Modification Installation
The system's adaptability allows installation across a wide range of AK variants without requiring permanent modifications to the host firearm. The two-piece mounting system secures into the rear trunnion while the adjustable front mount ensures precise receiver alignment.
Technical Innovations and Design Features
Precision Engineering Solutions
The adjustable front mounting system eliminates common AK optics mounting problems, including:
- Bolt carrier interference issues
- Shell casing ejection problems

Weight Optimization
Strategic lightning cuts throughout the cover reduce overall weight while maintaining structural integrity, ensuring the platform remains balanced and maneuverable.
