Delta Armory GP STRIBOG SP10A3 Alpha Upgrade - Black / Tan

GP STRIBOG SP10A3 Alpha by Delta Armory

Looking for the first official airsoft AEG replica of the Grand Power STRIBOG? Want a modern PDW that’s made exactly from the real-steel drawings? Need a rugged CNC upper and premium Upgrade-spec internals with no extra tuning required? The STRIBOG SP10A3 Alpha Upgrade is for you. It features fully licensed markings from Slovak manufacturer Grand Power, the company behind the PCC concept STRIBOG SP10 in 10mm AUTO. The replica follows the real-steel blueprints so closely it will delight any Mil-Sim operator. You also get a realistic semi-transparent magazine with dummy rounds to check remaining BBs at a glance, plus ambidextrous controls. The Alpha version sports a one-piece CNC aluminum upper with an M-LOK handguard for accessories like weapon lights and PEQ boxes.
A bottom RIS rail section on the handguard lets you mount foregrips for steadier shots. There’s a full-length top RIS rail on the upper for any red dot, compact scope, or magnifier. A modern touch is the metal stock adapter with RIS/1913 rail and a rear QD sling socket for mounting RIS / 1913 stocks—the same style used on the Sig Sauer MPX. The outer barrel is metal with a standard 14 mm CCW thread for suppressors.

Upgrade configuration with Eagle ETU unit

Delta Armory offers the STRIBOG in three internal setups: Standard, Upgrade, and Diamond. The Upgrade variant comes with carefully selected reinforced internals and, like the others, includes the Eagle ETU electronic unit with a metal flat trigger. The Eagle ETU delivers a snappy trigger response and lets you fully utilize 11.1V Li-Po / Li-Ion batteries that sit above the gearbox via wiring with a T-Dean connector. It also offers extensive tuning options including trigger sensitivity, screw-adjustable pre-travel, and multiple fire modes—from single-only through 3- and 5-round burst, full auto, up to a sniper mode with shot delay.
The reinforced V2 gearbox (Tokyo Marui standard) is fitted with top-tier upgrade parts including a full-steel-tooth piston with CNC piston head, CNC cylinder head and CNC aluminum nozzle, plus a stainless cylinder, stainless spring guide, CNC gears 16:1 and 8mm ball bearings. A high-torque motor with strong neodymium magnets drives the set. Accuracy is handled by a rotary hop-up chamber and a 6.03 mm tightbore inner barrel. The QRS Gen2 quick-change spring lets you swap the spring (adjust power) simply by removing the 1913 stock adapter—no need to pull the gearbox from the receiver.
