The Specna Arms SA-B11 URX SAEC™ System is a metal-framed electric weapon modeled after the M4A1 assault rifle, which is equipped with the URX rail system. The URX rail combines URX's proprietary mounting points and a 22 mm Weaver / RIS rail, allowing the user to customize the weapon to their own preferences with accessories sold separately.
SAEC™ quick spring change system
SAEC™ enables very fast spring changes compared to traditional quick spring change systems. In a SAEC™ system weapon, spring changes only require twisting the buffer tube locking ring, after which the buffer tube can be turned and pulled out of place. After this, you can unscrew the spring guide from the screw found under the buffer tube.
This model represents the latest "Upgraded" model series of Specna Arms metal-framed rifles.
Features of the Generation 2 version:
- Steel wheels
- 8 mm ball bearings
- Steel spring guide
- Lightweight, polymer piston
- Aluminum piston head
- Aluminum cylinder head
- Aluminum nozzle with o-ring
