Let’s Dive into DoubleStar M4 Mortar Plate
The DoubleStar M4 Mortar Plate promises to add versatility and functionality to any AR-15 platform. Designed as an entry-type stock alternative, it aims to provide a stable platform and multiple sling mounting options. DoubleStar claims that the robust build quality and thoughtful design make it a valuable addition for tactical and recreational shooters alike.
My interest in the DoubleStar M4 Mortar Plate stemmed from a need for a more stable shooting platform on my AR-15, particularly when maneuvering in tight spaces. I also wanted more flexibility in sling attachment points for various carry styles. Prior to this, I was using a standard adjustable stock, which felt limiting in certain tactical scenarios.
Upon unboxing, the DoubleStar M4 Mortar Plate immediately impressed me with its solid feel. The machined billet aluminum construction and Type III hard coat anodized finish exuded quality. Its weight, at 21 ounces, felt substantial without being overly cumbersome.
Compared to Magpul’s offerings like the CTR stock or BCM’s Gunfighter stock, the DoubleStar M4 Mortar Plate offers a different approach. While those stocks prioritize adjustability and lightweight design, the Mortar Plate focuses on stability and mounting options, including the small picatinny rail section. I chose the DoubleStar M4 Mortar Plate hoping for a more robust and versatile platform for certain specific shooting needs.
My first impression was excitement tempered with a bit of skepticism. The build quality was undeniable, but the Allen head screw for securing it to the buffer tube raised a slight concern about quick adjustments in the field, based on the user feedback I had seen.
Real-World Testing: Putting DoubleStar M4 Mortar Plate to the Test
First Use Experience
I tested the DoubleStar M4 Mortar Plate at my local shooting range, focusing on drills that involved transitioning between standing, kneeling, and prone positions. I also used it during a mock urban patrol scenario I set up on my property. The weather was dry but dusty, typical for late summer in my area.
The Mortar Plate provided a surprisingly stable platform when shooting from unconventional positions, such as resting the rifle against a barricade. The added weight helped reduce muzzle rise and recoil slightly. However, the Allen head screw proved to be a minor inconvenience when I needed to quickly adjust the plate’s position on the buffer tube.
After about 50 rounds, I noticed a slight wobble. I had to retighten the Allen head screw; this became a recurring issue.
Extended Use & Reliability
After a few weeks of consistent use (approximately 500 rounds fired), the wobble became more pronounced, even with repeated tightening. The finish held up well, showing no visible scratches or wear, but the functionality was compromised. Cleaning was simple, requiring just a wipe down with a gun cleaning solvent and a brush.
My previous experience with aftermarket stocks from reputable brands like Magpul was far superior in terms of reliability and ease of adjustment. The DoubleStar M4 Mortar Plate‘s Allen head screw design and potential for wobble were significant drawbacks compared to those stocks’ user-friendly features. The one user review about the bolt hole breaking was also in the back of my mind.
Breaking Down the Features of DoubleStar M4 Mortar Plate
Specifications
The DoubleStar M4 Mortar Plate is constructed from 7075-T6 Aluminum, providing a high strength-to-weight ratio. It weighs in at 21 ounces, contributing to the overall stability of the rifle. Its length is 2 inches, offering a compact profile.
The plate is compatible with both commercial and mil-spec receiver extension tubes, adding to its versatility. It features a Type III hard coat anodized finish for enhanced durability and corrosion resistance. The specifications are critical to consider for any shooter looking to optimize their AR platform for specific tactical or recreational purposes; for example, the compatibility with different buffer tubes ensures that a wide variety of AR builds are suitable for this product.
Performance & Functionality
The DoubleStar M4 Mortar Plate‘s primary function is to provide a stable and versatile platform for shooting and sling attachment. While the stability is good initially, the loosening issue hampers its effectiveness over time. The five quick-detach sling swivel pockets offer excellent flexibility in sling configuration.
The main weakness lies in the clamping mechanism’s reliability, or lack thereof. The design needs improvement to ensure a secure and consistent fit. Unfortunately, the loosening issue prevents the DoubleStar M4 Mortar Plate from fully meeting my expectations, especially after the single negative user review that mentioned a thin sliver of aluminum failing.
Design & Ergonomics
The DoubleStar M4 Mortar Plate‘s overall design is visually appealing and feels solid in hand. The machined aluminum construction gives it a premium look and feel. However, the Allen head screw is not ideal for quick adjustments in the field.
The plate’s compact size contributes to a balanced feel on the rifle. However, the ergonomics could be improved by using a more user-friendly attachment mechanism.
Durability & Maintenance
The DoubleStar M4 Mortar Plate‘s aluminum construction and hard coat anodized finish suggest long-term durability. However, the loosening issue raises concerns about the lifespan of the clamping mechanism. Maintenance is straightforward, requiring only occasional cleaning and lubrication.
The Allen head screw might require replacement over time if it becomes stripped or damaged. The potential for failure of the clamping mechanism is something users should be aware of and monitor.
Accessories and Customization Options
The DoubleStar M4 Mortar Plate includes a small Picatinny rail section on the base for mounting monopods or other accessories. It also accepts .5″ or 1″ recoil pads, allowing for customization of length of pull. The five quick-detach sling swivel pockets provide ample options for sling attachment.
The plate is compatible with standard AR-15 buffer tubes and sling attachments. It’s worth noting that specific monopods or recoil pads may require additional hardware for proper installation, so verify compatibility before purchasing.

Who Should Buy DoubleStar M4 Mortar Plate?
The DoubleStar M4 Mortar Plate is perfect for tactical shooters or recreational users who prioritize stability and sling mounting options over quick adjustability. It could benefit those who frequently shoot from barricades or other unconventional positions, where the added weight and solid construction can enhance stability. Those seeking multiple sling attachment points will also find this product useful.
This product should be avoided by shooters who require frequent and rapid adjustments to their stock configuration. Users who prioritize lightweight setups might also find the DoubleStar M4 Mortar Plate too heavy. Anyone needing absolute reliability in harsh conditions might want to consider alternatives with a more robust attachment system.
A must-have modification would be to replace the Allen head screw with a quick-adjust lever or thumbscrew, addressing the biggest usability issue. A dab of thread locker could help mitigate the loosening problem, though monitoring will still be required.
Conclusion on DoubleStar M4 Mortar Plate
The DoubleStar M4 Mortar Plate presents a mixed bag. Its solid construction, versatile sling mounting options, and enhanced stability are definite positives. However, the loosening issue and the inconvenient Allen head screw detract significantly from its overall value.
At a price of $65.99, the value proposition is questionable, given the reliability concerns. While the materials and design have potential, the execution falls short.
I cannot wholeheartedly recommend the DoubleStar M4 Mortar Plate in its current form. The stability and mounting options are appealing, but the loosening issue and attachment mechanism are significant drawbacks. If DoubleStar addresses these concerns in a future revision, it could become a worthwhile product. For now, I would suggest exploring alternative stock options with more reliable adjustment systems.
