Give your Umarex Gauntlet SL25 rifle a fresh new look and feel with this modern AR-style tactical chassis upgrade kit. Designed to replace the factory lower and handguard, this lightweight upgrade transforms the rifle’s physical appearance into a sleek, tactical AR-inspired platform.

The kit includes a precision lower replacement and a streamlined handguard featuring M-LOK mounting slots and an integrated bottom Picatinny rail, allowing for easy attachment of accessories while keeping overall weight down. The result is a more aggressive, modern aesthetic combined with improved modularity and handling—bringing new life to your Gauntlet SL25. This kit is only compatible with the SL versions of the Gauntlet Side Lever version.
