This LDC is threaded for 14mmx1mm left hand threads found on the Crosman DPMS SBR, as well as many airsoft guns. On a stock setup, I measured a 11.1 dB average decrease from 15 feet in front of the muzzle. Since this airgun has a blowback design, the airgun makes a lot of mechanical sound near your ear.

Specifications:

• • • Overall length: 5"
    • Diameter: 1.2"
    • Contruction: 3D printed ABS monocore set in a polymer shell with a optional decorative vinyl wrap
    • 14mmx1mm left hand threaded installation

Installation

To install, unload your airgun, put it on safe, and depressurize. Remove any thread covers. Taking care not to cross thread, screw the LDC on - the threads are reversed from normal, so it is lefty tighty, righty loosey!

If you have any questions, please feel free to ask me!
