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 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 for use with the 6” or longer barrels. Until more threaded barrel options are available, use with a suppressor may be possible but will be limited by overall diameter. When paired with 6.50” barrels, suppressors with a diameter of ~1.00” at the threaded end may work but cannot be guaranteed.
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. If you’re planning to run suppressed this is the suggested model.
Eack kit includes
(1) 6-32 T15 screw for the rear mounting point of both Picatinny and MLOK versions — suggested torque value for installation 15 in-lbs
Optics plates - (2) 10-24 screws and (2) MLOK T-Nuts — suggested torque value for installation on NEXUS 25 in-lbs, suggested optic torque value 15 in-lbs.
**Only the Short and Short V HELPeR models will clear NEXUS for tool-free disassembly.
**This kit utilizes the (2) factory 6-32 x 5/16 TORX screws from the OEM shroud.
**Ability to remove slide depends on combination and type of attached accessories and their hardware.
**3rd party MLOK accessories may need shorter 10-24 screws to clear slide for disassembly, available in the Hardware section.
**Please observe Magpul’s max torque values for MLOK; 35 in-lbs for metal accessories and 15 in-lbs for polymer accessories.
**Use of barrels less than 6” is not recommended or encouraged.
**Vibra-Tite VC-3 Threadmate is recommended for installation.
