The NEXUS system adds modularity to the Flux Defense Raider 365 and allows adaptability across various types of setups. This mounting system gives you a choice of 1913 picatinny, direct mount or an MLOK pattern mounting system for optics, lights and other accessories, such as the Raider Thumb Rests. Allows for removal of slides through the shroud for tool-free disassembly with no need to re-zero, this applies to all Sig OEM slides, including the FUSE.
Designed and made in the US, A20X Aluminum
NEXUS is intended as a direct replacement for the OEM shroud for use with the 6” or longer barrels. Allows for tool-free disassembly with Short and Short V models of HELPeRs.
NEXUS K drops the front flare of the shroud to increase compatibility with most suppressors when paired with a 6.50” threaded barrel. Being shorter overall this model also reduces the top MLOK slots from 2 to 1.5, but maintains full compatibility within the NEXUS ecosystem. Allows for tool-free disassembly with Short and Short V models of HELPeRs.
NEXUS SD allows for nesting a suppressor ~1.35” OD or less when using the P365 XL or FUSE slide barrel. Allows for tool-free disassembly with all models of HELPeRs including the Tall and Tall Portal.
