Henry Big Boy X Model .44 Magnum

The rifle itself marries classic lever-action charm with modern functionality, offering a robust and sleek design. Shooting it is a joy, with the .44 Magnum providing a thrilling yet manageable experience. It’s a standout at the range, both in performance and aesthetics.

RPP MLOK Handguard

An essential component of this build is the Ranger Point Precision MLOK Handguard. This handguard strikes an impressive balance between sleek design and tactical functionality, aligning perfectly with my vision for a tactical, modern lever-action rifle.

What sets this handguard apart is its MLOK system, allowing for a high degree of customization. This feature is crucial for personalizing the rifle with various accessories, tailoring it to specific needs and preferences. The MLOK slots offer both versatility and a secure mounting platform for any add-ons.

In terms of aesthetics, the RPP MLOK Handguard contributes significantly to the rifle’s overall look. It gives the rifle the “space cowboy” tactical look I was looking for. RPP offers a few different colors but being my first tactical lever build I went for the black.

As for the feel and ergonomics of this handguard I personally think it’s fantastic. This handguard offers a very light weight feel. The width is perfect making it a pleasure to hold while still being able to add grip panels without making the rifle feel bulky. We’ll touch more on those later!

RPP Adjustable Butt Stock

Another key upgrade in my build is the Ranger Point Precision Adjustable Butt Stock. This stock complements the RPP MLOK Handguard perfectly, both in function and aesthetics. Its design seamlessly mates with the rifle, enhancing its overall appearance while maintaining a tactical look I was aiming for.

One feature I love about this buttstock is its ergonomic grip. It’s exceptionally comfortable to hold, making a noticeable difference in handling. The grip’s design not only improves comfort but also contributes to the rifle’s tactical appearance.

In terms of functionality, the adjustable nature of this butt stock is a significant advantage. It allows for customization in height, accommodating various sights and scopes. This adaptability is essential for a build focused on versatility and precision. Additionally, the inclusion of MLOK slots on the bottom of the stock further extends its capability for customization.

Another highlight is the recoil pad. It offers a very comfortable feel not to hard and not to soft, I’d place it somewhere right in the middle. It does a great job dampening recoil and is a pleasure to shoulder.

Meprolight M22 Sight

For this build, I opted for the Meprolight M22 reflex sight. Its slim profile complements the rifle’s aesthetics, and I wasn’t constrained by rail space, making it an ideal choice. The M22’s unique design adds a unique touch to my lever-action build. Its always-on, battery-free illumination ensures reliability in various lighting conditions, aligning perfectly with the build’s tactical and functional goals.

On the range, the M22 performed flawlessly. The triangle reticle was fast to pick up and stayed crisp in all lighting conditions, bright during the day and still easily visible in low light. Zero held steady through hundreds of rounds, and I never had to think about batteries or re-zeroing it. It’s just always ready. Full Meprolight M22 review – click here.

RHINO 5″ Picatinny Rail Scope Mounts

For mounting the Mepro M22 on my Henry Big Boy X Model, I selected the RHINO 5″ Picatinny Rail Scope Mounts. This rail provides a stable, secure platform for the optic. It attaches easily to the top of the receiver with three screws.

The rail’s length allows for flexible positioning of the sight, aiding in achieving the best eye relief and sight alignment for my personal preference. Its integration with the rifle is seamless, maintaining the firearm’s sleek appearance while offering the versatility to accommodate different optics in the future.

Slate Black Industries Foregrip Accessories

In enhancing the grip and control of my Henry Big Boy X Model, I opted for the Slate Stop + Slate Grip MLOK Bundle from Slate Black Industries. This bundle includes two 3-slot MLOK panels, one 2-slot MLOK panel along with a Slate Hand Stop, all crafted from durable fiberglass-reinforced material.

The MLOK panels struck a perfect balance in grip texture – not overly aggressive, yet sufficient to provide a steady hold. Their medium grip texture and slim profile were exactly what I needed. They maintain the sleekness of the MLOK Handguard while offering the additional grip and tactile feedback I was looking for.

The Slate Hand Stop was a deliberate choice over a traditional grip. I found that a hand stop is a little more practical for a lever-action rifle like this. It offers the necessary maneuverability and secure grip, especially while operating the lever. The hand stop also aids in exerting backward pressure, contributing to improved recoil control. And on top of that they look amazing on this build!

Overall, the Slate Black Industries foregrip accessories fit seamlessly into this build, enhancing both the functionality and aesthetics of the rifle. Their effectiveness and design have certainly made them a go-to choice for my future builds.

RPP 6 Round Quiver

A tactical lever-action build isn’t complete without a quiver, which is why I added the Ranger Point Precision 6 Round Quiver to this build.

One important note for those considering this upgrade: to attach the quiver, you need Ranger Point Precision’s MLOK panel machined to fit on the RPP Buttstock. This panel secures with three screws, creating a sturdy base for the quiver. Once installed, the 6 round quiver secures to the panel, using the MLOK system for a secure and seamless integration.

The quality of both the accessory panel and the quiver is impressive. They feel robust and well-crafted. The panel fit perfectly and bolted on with no issues. The quiver holds the rounds snugly, ensuring they stay in place during movement, which is crucial for any tactical application.

Overall, I’m very satisfied with the RPP 6 Round Quiver. It fits perfectly with the build, both in terms of aesthetics and practicality, doing its job with no complaints.

Hoptic USA Mini Quiver

To further enhance my Henry Big Boy X Model, I incorporated the Hoptic USA Mini Quiver on the Handguard. This addition serves as a quick and easy solution for accessing extra rounds, enabling rapid and efficient reloading directly into the chamber.

Initially, I contemplated adding another RPP 6 Round Quiver on the Handguard, in addition to the one on the buttstock. However, upon further consideration, I realized that for practical purposes, the Hoptic Mini Quiver made more sense. While it holds fewer rounds (only two), its design and placement allow for swift, fluid motion when reloading – an essential factor in high-pressure situations.

This quiver mounts using one MLOK slot which means you can personalize the orientation of the quiver. By positioning this quiver sideways, having the rounds inline with the chamber, they can be quickly slid out and loaded. This design element greatly enhances the rifle’s functionality, allowing for those crucial extra shots to be chambered smoothly and swiftly.

Quality-wise, the Hoptic Mini Quiver is exceptional. Its construction is robust, and it integrates seamlessly with the rifle’s aesthetics. The balance it strikes between secure round-holding and ease of access is exactly what I was looking for in this build.

RPP Cheek Riser for AR Height Optics

To accommodate the higher position of the Mepro M22 on this build, I added the RPP Cheek Riser, which was designed for AR height optics. This cheek riser, made of Delrin, a durable plastic material, attaches securely to the top of the stock with two supplied screws.

While searching for a suitable cheek riser, I found the options somewhat limited, leading me to choose the RPP riser since I did use the RPP Buttstock. Initially, I had some reservations about its fit and aesthetics. However, once installed and put to use, the cheek riser started to grow on me. I mean it does it’s job and doesn’t take away from the look of the rifle. One flaw I’ve found is it slightly overhangs on one side.

I won’t lie I wished they incorporated an adjustable MLOK-compatible cheek riser, which could offer more adjustability and customization, especially if it could integrate with an MLOK panel on the opposite side of the buttstock. Such a feature would enhance the precision of the adjustments and add to the rifle’s tactical functionality. But being that the Buttstock is already adjusted I completely get why they don’t.

The RPP Cheek Riser works well for its intended purpose. While it’s not exactly what I initially envisioned, it doesn’t detract from the overall experience with the rifle. For now, it remains a suitable component of the build, and I don’t foresee a need to replace it.

Arid MFG ARS Mod 1

I chose the Arid MFG ARS Mod 1 Sling. Its slim profile complements the rifle’s aesthetics. Performance-wise, the ARS Mod 1 has been outstanding. The self-stowing feature keeps the sling neatly tucked away when not in use, preventing any snagging issues. Adjustments are smooth and secure, and the all-metal hardware feels robust and reliable. After extensive use, it has held up exceptionally well, showing no signs of wear or fraying.

Build Overview

As I step back and admire the completed build of my Henry Big Boy X Model, it’s clear that the vision of a “Space Cowboy” as they call it, Tactical lever-action rifle has been fully realized. The build not only meets but exceeds my expectations in both looks and performance.

Starting with the aesthetics, the rifle has a unique blend of modern and tactical charm. The combination of the parts and accessories gives it the distinctive “space cowboy” flair that’s eye-catching while still being functional.

The RPP Buttstock stands out for its comfort and ergonomics. It’s very comfortable to shoulder, and the grip feels just right in my hand. The width of the RPP Handguard is perfect for my self, not too bulky, while maintaining a sleek profile while offering MLOK capabilities and a comfortable grip.

One highlight of the build, both in terms of looks and performance, is the addition of Slate Black Industries grip panel and hand stop. These accessories significantly enhance the handling of this build. The grip panel ensures a strong and comfortable hold, while the hand stop subtly aids in recoil control, just as I wanted.

The quivers from RPP and Hoptic USA not only add to the rifle’s tactical look but also to its practicality. Being able to carry an extra 8 rounds on the rifle is a significant plus, making it ready for any scenario.

Performance-wise, the Mepro M22 has been a game-changer. It’s an outstanding optic for the price, and I’ve particularly enjoyed using the triangle reticle. Click here for a detailed review of the Mepro M22.

In conclusion, this build is not only a blast to shoot at the range, but also a real head-turner. Its performance, appearance, and the sheer enjoyment it brings me have made me question why I waited so long to pull the trigger on this build.
