The OctoArms LEVIPS90 P90 / PS90 7-Slot Weapon Light Under-Barrel Mount is an extended Picatinny rail designed to place a weapon light, IR illuminator, or similar accessory in a more useful under-barrel position on the FN P90 and FN PS90 platform.

This mount was originally known online as the LEVIPS90, after designer Levi Wade’s long-running levips90 username on firearm forums and social media. Levi has since brought these designs under the OctoArms name, but the LEVIPS90 name remains important for customers who know the product from years of forum discussion, user photos, and word-of-mouth recommendations.

The idea behind the mount came from a simple problem: standard side-mounted rails can add unnecessary width and place lights too high or too far from the support hand. The LEVIPS90 under-barrel design keeps the accessory closer to the natural support-hand position, making light activation more intuitive while preserving the compact, distinctive handling of the P90 / PS90 platform.

This 7-slot version provides additional rail space compared to the compact 4-slot model, making it a better choice for longer weapon lights, IR illuminators, tape switch placement, or users who want more positioning flexibility under the barrel. It is especially useful for PS90 owners building a practical defensive, range, or night-capable setup and for P90 / PS90 users who want a cleaner alternative to wide side-mounted accessory rails.

The LEVIPS90 mount is made from 6061-T6 aluminum with a hard black anodized finish and black oxide finished screws. It is made in the USA and reflects the practical, enthusiast-driven design approach that led from the original levips90 forum-era mounts to today’s OctoArms product line.
