Zaffiri Precision Complete Upper Features The Zaffiri Precision Complete Upper uses the Integrated Blowhole System to blend the ZPS.1 slide shape with a built-in compensator managing propellant gas to flatten muzzle rise during rapid fire. Because the gas management is integrated into the slide itself shooters gain compensated performance without needing to run a threaded barrel setup. The single billet 17-4 stainless steel construction is machined to tight tolerances which Zaffiri Precision states increases both accuracy and overall performance on the Glock 43X platform. The Flat Dark Earth finish gives the slide a distinct look while standing up to daily carry and use. This upper is cut for the RMR footprint so a wide selection of popular red dot optics can be mounted directly without an adapter plate. The slide is manufactured entirely in Florida reflecting Zaffiri Precision s focus on domestic production and tight quality control. Shooters looking to upgrade their Glock 43X with one of the better-regarded aftermarket slides on the market will find this a straightforward drop-in option.
