RRA SA-C02 CORE Airsoft electric gun - black
Rock River Arms Licensed AR-15 Airsoft Replica with ESA™ Quick Spring Change System
Officially Licensed by Rock River Arms
This replica features complete, licensed markings from Rock River Arms—a respected U.S. firearms manufacturer known for producing high-quality AR-15 carbines. Founded in 1996 by the Larson brothers and Les Baer in Colona, Illinois, RRA supplies AR-15 rifles to elite U.S. agencies including the DEA, FBI, and U.S. Marshals.
Innovative ESA™ Quick Spring Change System
The replica is equipped with the ESA™ (Easy Spring Access) system, allowing rapid adjustment of muzzle velocity without special tools or disassembling the gearbox. Simply remove the stock slide to access and swap the spring—perfect for adapting to different field limits or game types.
This system offers maximum flexibility for players, especially under varied field regulations. Adjusting the replica’s power ensures the best balance between performance and safety for both the user and other participants.
High-Quality External Build
The receiver, stock slide, handguard, SF-style stock (with battery compartment), and pistol grip are made from lightweight, nylon-reinforced polymer—offering a strong yet weight-reducing alternative to metal. Fiberglass reinforcement further improves impact resistance and durability.
Metal components include the barrel, flash hider, enlarged charging handle, and sling swivels. Steel is used for structural elements such as the screws, pins, mock bolt carrier, and ejection port. All parts fit together precisely with no wobble between the upper and lower receiver.
Optimized for Dynamic Gameplay
The lightweight and balanced construction makes this replica ideal for dynamic skirmishes or long-duration mil-sim events. The adjustable, anti-slip stock allows for comfortable use across different player builds and preferences. The 14 mm CCW threaded flash hider also supports optional silencer attachments.
Battery and Power Options
- Fully compatible with LiPo and LiFe batteries
- Default installed spring delivers ~380 FPS – perfect for medium-range engagements
- Included M90 spring lowers velocity to ~310 FPS for CQB and indoor use
Reliable and Durable Gearbox
The internal gearbox is built for performance and durability. It includes:
- 8 mm slide bearings
- Shimmed steel gear set
- Four anti-reversal latches for stability
- Polycarbonate piston with a full steel rack
- Type 1 cylinder
- Steel circuit-breaker
- Rotary-style Hop-Up chamber
The components are durable enough to handle springs up to M140, offering future upgrade potential without requiring part replacements.
Precision Barrel and Hop-Up
A 6.03 mm precision inner barrel works in tandem with the rotary Hop-Up system to provide excellent accuracy and consistent range. This setup is ideal for players who demand precision shots in mid-range engagements.
