Sig Sauer ROMEO MSR Gen II FOXTROT MSR Red Dot Sight and Compact Weapon Light Combo SORMSR101 FMSRC UPC 798681746095
Product Description
The Sig Sauer® ROMEO-MSR™ Gen II and FOXTROT-MSR™ Compact Tactical Light Package (SKU: SORMSR101-FMSRC / UPC: 798681746095) delivers an all-in-one targeting and positive weapon identification solution engineered specifically for modern sporting rifles, carbines, and defensive shotgun platforms. Combining Sig Sauer's next-generation 1x20mm compact red dot sight with a high-output 1,350-lumen tactical white light, this factory-matched deployment kit provides carbine operators with instantaneous target acquisition in daylight, low-light, and no-light environments right out of the box.
Both devices are CNC-machined from solid aircraft-grade 6061-T6 aluminum housings treated with a rugged MIL-A-8625 Type III Class 2 Hardcoat Anodize in non-reflective matte Black. The ROMEO-MSR Gen II optic utilizes fully multi-coated, anti-reflective lenses encased in an O-ring sealed and nitrogen-purged housing that achieves complete IPX7 waterproof and fogproof reliability. Up front, the FOXTROT-MSR Compact light is built to withstand punishing muzzle blast and sustained recoil forces, featuring an impact-resistant optical lens and sealed battery compartment that delivers high thermal dissipation during extended tactical engagements.
Targeting performance centers around a precise, parallax-free 2 MOA red dot powered by an intuitive top-mounted rotary dial featuring 12 brightness positions (10 daylight and 2 dedicated night-vision levels) delivering up to 35,000 hours of continuous runtime on a standard CR2032 coin cell. The redesigned skeletonized see-through riser provides a 1.41" absolute co-witness height that permits the seamless use of iron sights. For target identification, the FOXTROT-MSR Compact harnesses a focused reflector producing 33,000 candela for aggressive photonic barrier penetration and 1,350 lumens of situational flood, controlled via an integrated tailcap push-button or the included remote pressure pad.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Direct Picatinny (MIL-STD-1913) interface for all flat-top AR-15, AR-10, MCX, MPX, and MSR upper receivers; FOXTROT-MSR light mounts to forward handguards via included M-LOK or Picatinny brackets. CRITICAL staging notice: When mounting the ROMEO-MSR Gen II riser to your upper receiver rail, push the optic forward against the front edge of the Picatinny cross-slot before applying torque. Recommended riser cross-bolt torque is 30 in-lbs. For the FOXTROT-MSR light, torque M-LOK mounting screws into aluminum handguards to 35 in-lbs (15 in-lbs for polymer handguards); if using the Picatinny cross-bolt clamp, torque to 20 to 25 in-lbs. Threadlocker (blue medium-strength) is pre-applied or recommended on all mounting fasteners.
- Ensure the host firearm is completely clear, magazine removed, and chamber visually and physically verified empty. Lock the bolt rearward before beginning rail installation.
- Select your mounting positions: stage the ROMEO-MSR Gen II on the forwardmost slots of the upper receiver rail (never bridging the receiver and handguard) and determine light placement at the 11 o'clock or 1 o'clock handguard position.
- Loosen the optic cross-bolt, seat the skeletonized riser onto the receiver rail pushing forward into the slot, and secure the clamp; position the FOXTROT-MSR light bracket onto the handguard M-LOK slots or rail and hand-thread fasteners.
- Using an armorer torque wrench, torque the ROMEO-MSR riser cross-bolt to 30 in-lbs; torque the FOXTROT-MSR light mount hardware to 35 in-lbs for M-LOK or 20 to 25 in-lbs for Picatinny; install the CR2032 coin cell in the top optic cap and insert the 18350 rechargeable cell into the light body.
- Inspect iron sight co-witness alignment through the skeletonized riser at 1.41" absolute height, test optic illumination across daylight and NV positions, test light tailcap and remote tape switch actuation, and verify optical zero at 25 or 50 yards prior to field staging.
Key Features
- Matched Tactical Carbine Package: Complete turn-key kit pairing the updated ROMEO-MSR Gen II 1x20mm red dot with the FOXTROT-MSR Compact rail-mounted white light.
