Delta Armory Grand Power STRIBOG™ SP10A3 AEG; Upgraded Version

If you’re into ultra-modern SMG designs, you’re going to love this one! The Delta Armory Grand Power STRIBOG SP10A3 AEG is designed based on the technical drawings of the real firearm, ensuring dimensional accuracy is as close to the real thing as possible and all the realistic details are authentically replicated.

This is the Upgraded version, equipped with the same superb internals as the popular FREYA™ Gen.2, including the usual complement of SHS reinforced parts with CNC aluminium compression group components, a 6.03mm tightbore inner barrel, 16:1 CNC steel high speed gears and a high torque motor to back it up. The EAGLE programmable MOSFET is also present, offering a wide range of programmable fire modes, including burst mode, binary trigger, adjustable pre-cocking and much, much more. Available in full metal ALPHA with a CNC aluminium upper or lightweight and agile CHARLIE with a high-density polymer upper, this versatile little beast has a variant for any playstyle or preference!

Starting at the front, we can find a thread protector concealing 14mm CCW male barrel threading beneath. 14mm CCW Male threading allows the most common tracer units and suppressors to be mounted, ideal for those who want to take the STRIBOG™ in a sneaky direction. The thread protector boasts knurling around the outside to make tightening and removing it a breeze, but once you’ve seen the STRIBOG™ with a suppressor or tracer, you won’t want to reinstall it!

Moving rearwards, we come to the monolithic upper receiver, made from either CNC aluminium if you choose the ALPHA™ version or from high-density polymer if you opt for the CHARLIE™ variant. At the 6 and 12 o’clock positions, we’re treated to a 20mm Picatinny rail, offering ample space for an optical sight of your choice, whether you go for a simple red dot sight or deck it out with a PEQ laser, red dot and magnifier combo. The bottom rail is ready to rock with a 20mm Picatinny vertical grip or bipod, but also makes a sweet spot for pistol-style tactical flashlights.

On either side, the receiver boasts 3 M-LOK negative space attachment slots, providing extra space for M-LOK accessories to be mounted directly. Pre-installed on the front M-LOK slots, we are generously kitted out with a pair of 20mm Picatinny rail adapters so you can make use of your existing 20mm Picatinny accessories. If you like to run your primary with slick sides for minimal snag potential, you can remove the rail adapters without needing rail covers to replace them, as is the benefit of M-LOK!

The receiver itself is the spitting image of the FN SCAR in SMG form, and when you dig into the real steel, you’ll understand why! Like the SCAR, the real steel STRIBOG™ is made with a monolithic receiver machined from an aluminium extrusion, thus the SCAR-like shape. At the very front of the receiver, you’ll find a front iron sight post recessed into the 20mm top rail; this is designed to be used with the STRIBOG™ in pistol configuration by indexing it in the centre of the weight-reducing cut on the top rail.

The charging handle, located on the left side of the SMG, provides access to the Rotary HOP-up adjuster so you can tune the STRIBOG™ for different ammo weights and get the perfect trajectory. Pulling the handle back will lock open the mock bolt carrier, revealing the adjuster inside the ejection port on the right side. Once your adjustment is complete, you can hit the bolt release catch on the left side, in the centre of the receiver, to return the mock bolt to battery and seal the HOP-up unit from dirt and debris ingress.

On either side of the upper receiver, the STRIBOG™ boasts authentic Grand Power trademarks, including the STRIBOG™ logo and “Designed in Slovakia” laser etched in bold, prominent text, matching the real deal to a tee. Being designed based on the technical drawings of the original firearm, Delta got this STRIBOG™ build bang on, including all the details present on the real deal.

Moving down to the lower, we can find a familiar fire selector configuration based on the M4/AR-15 platform, offering 3 fire modes with a 90-degree throw between each. This is great news, as the fire selector is one of the best aspects of the AR design, being easy and fast to work under pressure without being easy to accidentally bump into the wrong mode. Just like the real STRIBOG™, the fire selector is ambidextrous and, mirrored on either side, ideal for left or right-handed shooters. The default fire mode options are safe, semi-automatic and fully automatic, but with the EAGLE™ ETU on board, you can reprogram the fire modes to a wide variety of alternative options, from burst modes to binary trigger and more!

The pistol grip is integral to the lower receiver, made from strong high-density polymer with a textured feel indicative of fibre reinforcement. On the flanks, the grip boasts dot texturing, and on the front and rear, it has linear gripping texture, providing plenty of traction for wet-weather operation, with or without gloves. The trigger guard is also built into the receiver, an enlarged design which provides plenty of space for full finger gloves. The trigger itself is the Delta Armory CNC Type A trigger, a flat trigger which is a near-perfect match for the real STRIBOG™ AP10 trigger, ideal for pumping out rapid double taps in CQB!

In front of the trigger guard, we can find the magazine release, a combination mag release similar in concept to the MP5, offering an AR-style push button mag release on either side and a low-profile paddle mag release just below. This gives you two options to choose from, each optimised for a different reload style. If you prefer retention reloads, the paddle mag release is ideal. If you aren’t bothered about battering up your mags or you’re accustomed to reloading an AR, the push-button mag releases are the best option for you. Both mag catch options are ambidextrous, making the STRIBOG™ one of the most lefty-friendly SMGs on the market!

The magazine well itself is significantly flared, making reloads a breeze, even if you’re new to it! The flare guides your magazine in and helps you avoid missing the magwell when working pumped with adrenaline, a feature previously found on platforms designed for competitive shooting but rapidly making its way onto more and more modern firearm designs. The magazine itself holds approximately 100 BBs and includes detailed mock 10mm AUTO cartridges visible through its transparent shell.

At the very rear of the receiver, the STRIBOG™ sports a 1913/20mm Picatinny stock interface, granting access to a wide variety of 1913 stocks, including MPX and MCX stocks, lightweight skeletonised stocks, Visor stocks, AR buffer tubes and more. Also built into this interface is a QD sling socket, ideally placed for a single-point sling. The 1913 interface is found on the most modern real steel firearms, being present on the MPX and MCX, various B&T SMG and rifle designs, and offered in the form of a stock adapter for practically everything else!

The battery compartment is inside the receiver, accessible through the rear by removing the 1913 interface. This also allows you to access the spring guide so you can tune power to perfection. To remove the interface, simply unscrew the 2.5mm Allen bolt inside the QD sling socket, and it can be lifted free. Inside, you’ll find a Deans battery connector to which you mount your choice of battery. We recommend a 7.4V 1000mAh LiPo battery in stick configuration for an easy fit, though you can fit slightly larger stick and nunchuck batteries inside if you’re careful.

Like the R-15 FREYA, the STRIBOG Upgraded Version combines the best of both the Delta Armory EAGLE™ and ETU series. The version 2 gearbox boasts CNC 16:1 ratio high-speed steel gears running on 8mm steel bushings to provide a killer rate of fire and a smooth, stress-free gearbox report.

The usual Delta Armory pre-upgraded parts are present, including an SHS piston with a full steel tooth rack, an SHS tappet plate and sector gear delayer, along with a CNC aluminium piston head, cylinder head and nozzle for maximum long-term durability. The cylinder is also CNC machined from steel, as is the quick-change spring guide. Unlike Delta’s AR-15 lineup, the STRIBOG boasts a “true” quick-change spring system, providing easy access to the spring by removing the 1913 interface on the rear, the same way you access the battery compartment.

The ultra-strong CNC gearbox parts are driven by a high torque motor with Neodymium magnets, kept in check by the EAGLE™ ETU/MOSFET system. The combination of the EAGLE™ and the internals from the previous ETU series is a match made in heaven, offering more programmable options than ever before with the strength and speed of Delta’s ETU internals. The ability to choose 3 or 5-round burst, binary trigger, sniper delay, semi-automatic only, AUG mode, trigger sensitivity settings, adjustable pre-cocking and active braking levels makes the Upgraded STRIBOG a real beast in whatever role you choose for it!
