With Glocktober closed, many of you may wonder how we could possibly have another giveaway lined up for November.
4 Glocks in 4 weeks? They told us we were crazy. They told us it wasn’t possible. They were wrong.
And now we’re proving them wrong again with a rifle to celebrate sci-fi cinema. This is our X39 Space Gun Giveaway.
If you’ve been keeping a finger on the pulse of movie releases, you know that there’s an upcoming film in a renowned science-fiction franchise. Regardless of your opinion on the series, its iconic blasters have a distinct style. If you look closely, you’ll notice that many of the prop blasters came from real firearms, adding a sense of realism and familiarity to the otherworldly environment.
Of course, nothing beats the realism of full function, so we’ve made our own take on a future-style modern blaster—a stylized AR15 chambered in 7.62x39.
Well, everyone knows that timeless cartridge will be around until the sun explodes. Plus, trajectories don’t matter if you’re in zero-gravity. But the real reason is that it’s a fun caliber, and the ammo is cheap enough to keep running all day.
If you want to know more about this carbine and the build process, keep reading. We’ll discuss the many ways you can take your stock rifle into the future with just a bit of elbow grease.
Starting the Build
For this build, we favored San Tan Tactical's STT-15 Pillar Billet Receiver Set. This receiver set is stylish and tightly fit, ensuring that we keep our aesthetic without compromising on reliability. These receivers also feature fully ambidextrous controls and an enlarged trigger guard and magwell. Add in some rear QD slots, and San Tan Tactical has set themselves apart with an intuitive receiver layout.
With a 7.62x39 AR, barrel selection is somewhat limited. Fortunately, Faxon Firearms had us covered with their 16” 7.62x39mm Mid-Length Gunner Barrel. Faxon Firearms is known for their high-quality barrels, which are made to strict ISO quality certification. Every barrel is fully stress-tested, air-gauge tested, and 11-degree target crowned for guaranteed accuracy. This barrel’s material quality is impeccable, so we’re likely to get some great groups.
With the barrel installed, we finish the assembly with a Battle Arms Development Low Profile Gas Block. BAD gas blocks performed well for us in the past, and the nitride coating adds a durable black sheen. Fitted with a mid-length gas tube from Aero Precision, our barreled upper is ready for the next steps.
The lower receiver comes assembled with its ambi controls, but we’ve still got to finish it with a few missing parts. A lower parts kit from Aero Precision takes care of any small parts, but the real pride comes from a match trigger from CMC Triggers. This flat-faced single stage trigger breaks at a crisp 3.5lbs, making it a considerable improvement for precision marksmanship. Plus, it’s backed with a 100% lifetime warranty, so you know it’s future-proofed.
The last piece of the lower is the buffer system. Since we’re using San Tan receivers, a San Tan 6-position Enhanced Buffer Tube Assembly Kit matches our build. With both receivers now functionally assembled, we can move on to the real iconic feature: the furniture.
If you’ve heard of Hera Arms, you know what we’re talking about.
If you haven’t, you’re probably wondering how our AR15 got morphed into a P90. Good question.
To complete our lower receiver, we installed the Hera Arms CQR Buttstock. This fixed stock integrates over your buffer tube like a fixed stock, and the thumbhole grip slots right into place. This covers both the stock and pistol grip portion of the rifle, and its rigidity makes it easy to keep the rifle on target.
But, to be honest, most people buy Hera furniture for the look. And you can’t blame them! Thumbhole stocks add a science-fiction look to any rifle, especially when they’re counterbalanced by a thumbhole foregrip.
Speaking of foregrips, our upper receiver deserves equal attention.
We can’t install a foregrip without a place to put it, so handguard selection comes first. With the trend of military procurements, M-LOK is the choice of the future, so we went with the Fortis 14” Night Rail. Fortis Manufacturing is known for making handguards with aggressive aesthetic, and the Night Rail is no exception. This handguard features a full top rail with recessed MLOK on the 3, 6, and 9 o’clock. At the front of the rail, these recessed sections jut out into short pic rails, giving the user more flexibility on their mounting choice. With plenty of QD sling slots, this handguard has the aesthetic and function our rifle needs.
Now that our handguard is installed, we can add that Hera Arms CQR Front Grip. Just like the stock, this foregrip mirrors the angles and cutaway of a P90 grip, adding to its futuristic appeal.
Completing the Rifle
At this point, our rifle is mostly complete, save for a few important last additions. First, we need to attach a proper muzzle device to match the rifle’s style. Second, we need a BCG and Charging handle that will function with the old soviet cartridge. Finally, we have to top our rifle with some innovative optics that elevate the rifle’s natural accuracy.
First up, the muzzle device. The Spikes TacticalBarking Spider 2 Krink brake might look strange at first, but once you’ve spent some time behind it, you’ll learn to appreciate its eccentricity. The Barking Spider 2 looks similar to other Krink brakes, but this muzzle device packs in a lot of modularity, allowing you to customize the performance of your rifle. It also enhances backpressure for superior function when paired with shorter barrels, but in this rifle, we’re just looking for compensation without blast. The construction is so robust, it can handle automatic fire from short barrels with ease. That’s an impressive achievement for any blast-reducing brake.
To get our rifle ready-to-fire, we need a BCG and charging handle that succeeds with 7.62x39 builds. FailZero makes an EXO Coated 7.62x39 BCG that runs just as well as their standard 5.56 models. FailZero’s bolt carrier groups are popular in the firearms community, as their EXO Nickel Boron coating offers superior lubricity for filthy cartridges. Most would agree that steel-cased 7.62x39 falls well into that category.
As for a charging handle, we knew we had to do an ambi setup to match the rifle. The Battle Arms Development RACK AR-15 Charging Handle isn’t just ambi though—it has an ingenious design that eliminates the roll pins, which are a common point of failure. The RACK’s smooth sliding latch prevents wear, while a patented straight pull unlock makes for quick unlocking for rapid clearance.
With our rifle assembled and ready, there’s only one last step. As with any precision system, optics are an important consideration when setting up your rifle. 7.62x39 isn’t a long-range cartridge, so we don’t need a high-power variable scope, but we’d still like to leverage our rifle’s natural accuracy with a quality optic.
An SLx 1-6x24 FFP Rifle Scope with the ACSS® Raptor 300BO/7.62x39 reticle packs every feature we need to maximize our effectiveness with this futuristic blaster. At 1x, this scope is quick on the target, allowing for snap marksmanship in close quarters. As range increases, turn up the magnification and use the ACSS reticle’s intuitive auto-ranging to hit targets out to 600 yards. Every aspect of the Raptor reticle empowers the user to deliver superior precision with minimal effort or calculation. That’s why we describe our ACSS system as the World’s Most Advanced Reticles. When it comes to future-ready optics, ACSS is just a cut above. (Author’s Note: Raptor 300BO/7.62x39 reticle calibrated to Earth’s gravity. Do not use this scope on other planets or areas with dissimilar gravitational acceleration.)
We put the SLx 1-6 on a Warne Gen 2 Skeletonized Extended 30mm MSR mount for reduced weight and greater freedom in mounting distance, and a pair of Midwest Industries CRS 45-degree offset iron sights round out the optics setup. With everything in place, this rifle is ready for close-range, long-distance, nighttime, and daytime operations.
Nobody can see the future, but we’re pretty sure that this rifle will be there.
If you’re lucky, it might be in your future too!
