LSD front is printed from 17-4 stainless and post machined to tight tolerances. This is because many of the features of the LSD can not be machined. It is attached to the UMMS SLK rear which is machined from hardened 4140 steel with a nitride finish. This model has no HUB threads.
***The left side of the LSD has 4 ports that are solid at the base. This is to give compensation for a right handed shooter. It is not a manufacturing defect. The bottom of the ports is thin and easily drilled through for a left handed shooter***
- Dramatically reduces flash and does so better than the A2 Flash hider on most setups.
- Recoil reduction similar to that of an aggressive muzzle brake with dramatically reduced concussion
- Pre-tuned compensation to make dot/reticle movement next to nothing.
- Modular U.M.M.S. design allows for HUB or SLK rear depending on your needs.
- SLK version is for those not planning to add a suppressor and want a sleeker package.
- Strategic gas vectoring to reduce debri when shooting from prone and keep a clear line of sight when shooting in low light.
- Weight: 4.2oz
- Extremely robust design that has been tested using SOCOM firing schedule tests with and without suppressors.
- All threads are class 3
- PCSL Practical and Competition division legal.
