Official COLT® license
The body is officially licensed by the COLT® brand, one of the most famous American manufacturers of real firearms with more than 180 years of tradition. On the left side of the lower receiver you will find the original stamping with the characteristic prancing horse in a circle - a symbol of quality and history of the brand that was at the birth of legendary rifles.
The rear of the receiver is threaded, allowing the spring guide to be screwed in easily through the buffer tube. Changing the gun's spring takes just a minute using a standard screwdriver—without needing to disassemble the rest of the weapon!
The body is made of aluminum alloy with a matte finish. All parts are also metal, the spring guide is made of stainless steel and features a ball bearing.
In addition to the upper and lower receiver, the package includes:
- Metal stock tube
- QD spring guide with bearing
- Dust cover
- Sliding receiver plate with the spring
- Body pin - screw version
- Bolt catch
- Magazine catch
- Charging handle with the spring
- Selector switch
- Central gearbox pin
The receiver is compatible with E&C, Specna Arms, CYMA, and TopArms brands. It may be compatible with other brands as well, but this has not been tested.
