Test Guns
Universal Receivers for Small to Medium Caliber. Precision. Rugged Performance.
Sydor Technologies offers a complete line of Universal Receivers built for rigorous ballistic testing across small to medium calibers. Configured for repeatable, precision-controlled firing, each receiver supports pressure, velocity, and accuracy measurements. Sydor’s Universal Receivers are manufactured for flexibility, safety, and reliability in the lab or range.
Key Benefits
- Multi-Caliber Compatibility
Small-caliber platform accepts calibers from .22 to 12.7 mm (.50 BMG), with optional adapters for rimfire and shot shells. The medium-caliber system supports .22 (via adapter) up to 30 mm projectiles. Both systems are ideal for diverse test environments.
- Heavy-Duty Construction
Built to withstand sustained use, the small-caliber receiver weighs ~52 kg and features a robust breech assembly with adjustable azimuth/elevation. The medium-caliber system doubles the mass at ~100 kg, for enhanced recoil control and structural integrity for high-energy testing.
- Safe, Remote-Ready Firing
Both platforms include 24 VDC solenoid actuation options for safe, remote-triggered operation. Manual firing modes also available.
- High-Precision Data Integration
Configured to interface with pressure transducers, piezo gauges, velocity screens, and optical targeting systems. Compatible with EPVAT and other ballistic instrumentation standards.
- Scalable and Accessorized
A full range of accessories is available, including interchangeable barrels, shot-test blocks, recoil mounts, control boxes, calibration tools, and spare parts kits, ensuring your system grows with your test needs.

Deployment-Ready Configuration
Each receiver system ships fully configured for its caliber class and includes the breech housing, firing mechanism (manual or electric), recoil mount, azimuth/elevation stand (medium caliber), and full electrical control unit. A wide selection of interchangeable barrels, pressure adapters, and mounting accessories are available to tailor the system to your exact testing protocol.
