MonoLift™ Riser - In between batches of fulfilling our 2022-Current UK MoD contract for the L143A2 MCX-SPEAR LT service rifle, the MonoLift Riser will be available for the commercial market in small batches. The MonoLift Riser was developed at the request of a UK MoD branch with specialized requirements to optimize the contract optics package (Sig Romeo 8T & Juliet 4) placement on their newly issued Sig MCX LT variants (L143A2) to an optical center of 2.26". The MonoLift Riser is also at home on various other platforms with many other optic, magnifier, & laser combinations when reversed. The MonoLift Riser utilizes the proven Scalarworks^® FUSE™ mounting hardware. The lower deck of the MonoLift is 0.725" above host Pic rail, higher deck is 0.850". Overrun, or intermittent contract shipment allocation is sold here. These are the exact same units that are fulfilling contracts around the globe. Optics are not included. Version 2 Markings started on contracts in 2026.

Features

• Places both Romeo8T and Juliet4 on the same 2.26” optical center for a better heads-up posture
• The lower deck of the Monolift is 0.725" above host Pic rail, upper deck is 0.850".
• Shortens Romeo8T and Juliet4 overall length footprint by 0.240”
• Two aligned retention holes for lashing or wiring Romeo8T & Juliet4 to the riser 
• Ability to place the Juliet4 up to 5 pic slots further rear vs direct attaching to the upper receiver
• Fits flush with the front of the Romeo8T. The MonoLIft riser also fills the void under the rear, eliminating snagging (slings, gear straps, etc).
• Removes the need for a spacer on the Juliet4 which achieves the following:
  • Reduces side profile by 0.140” when deployed 
  • Eliminates tolerance stacking on the Juliet4 by omitting the OEM spacers, which tend to cant.
• Includes T25 Torx Driver Bit
