A new replica from the Slovak Delta Armory company was presented at the IWA 2025 trade fair, which you can read about HERE. Currently, the Slovak distributor's website offers the product in three variants: CHARLIE, CHARLIE Upgrade, and ALPHA Upgrade.
The most basic and cheapest version, CHARLIE, is made of polymer, which significantly affects its weight — 1845g. This version comes with standard-quality internal components and costs 181,80 €. 
The slightly more expensive CHARLIE Upgrade costs 229,30 €. For this price, you get better internal components, such as a cylinder head, 16:1 gear set, and CNC-machined nozzle, as well as a steel cylinder and a High Torque motor. The upgraded version weighs 1910g. 
The most expensive replica, Stribog, costs 292,70 €. It comes with the same components as the CHARLIE Upgrade, with one exception: in the ALPHA version, the upper part of the receiver is made of CNC-machined aluminum. This affects the weight of the replica, which in this case is 2110g.
It is worth mentioning that regardless of which replica you choose, each one is equipped with an optical, trigger-programmable EAGLE system. In the box, aside from the replica, you'll find a mid-cap magazine, a small hex key, a card with a QR code linking to the EAGLE electronics manual, and a printed user manual in multiple languages — surprisingly, including Polish. However, a noticeable oversight is the lack of a tool to unscrew the battery compartment cover. 
The Stribog SP10A3 is a licensed product bearing the markings of the real firearm. Notably, the manufacturer has developed dedicated 11.1V 1100 mAh LiPo batteries with shortened wires specifically for this replica, which fit perfectly into the designated compartment. 
To fairly assess the quality of these replicas, we purchased two units: the cheapest and the most expensive one. In both cases, after unboxing and setting the hop-up, we measured the kinetic energy of the shots. For this, we used G&G Armament BBs weighing 0.25g. The ALPHA produced approx. 1.4 Joules on the stock spring, and the CHARLIE approx. 1.48 Joules on the stock spring. After replacing the spring with an SHS 90, we repeated the chrono test. This time, the ALPHA produced approx. 0.89 Joules and the CHARLIE approx. 0.95 Joules. The spring change was very simple and the entire process took just a few minutes. 
The replica is sold without a stock. The manufacturer assures that stocks will be available as an additional accessory, but for now, they are notyetavailable. Two stock variants will be available, each priced at around 43,90 €.
Accessories currently available for purchase include:
- 110 BB mid-cap magazine priced at 11,80 €
- 11.1V T-con LiPo battery priced at 19,80 €
- Defender 2 Stribog tactical flashlight priced at 58,40 €
