Atlas Custom Works Stainless Steel Lightweight Hammer and Strut for Marui / WE / ARMY Hi-Capa, Gold

Trigger response on a Hi-Capa comes down to mass. The heavier the hammer, the more energy it takes to get it moving, and the more delay you feel between pull and break. A lightweight hammer reduces that mass, which means the sear releases more crisply and the slide cycles faster when paired with a matched spring and guide rod.

This set from Atlas Custom Works is a steel hammer and strut designed for the Marui, WE, and ARMY Hi-Capa platforms. Steel construction holds up to high round counts better than aluminum or polymer alternatives, and the reduced weight helps with both trigger feel and overall cycle time. The gold finish is cosmetic—it does not indicate a specific FPS rating or performance band.

Fitment varies. Hi-Capa clones and aftermarket parts do not always follow the same internal dimensions. While this set is specified for Marui/WE/ARMY pattern pistols, some frames may require light stoning or fitting to achieve proper sear engagement. If you are not comfortable with gunsmith-level work, budget for professional installation.

What else you'll need. A hammer and strut alone will not guarantee a cleaner break. You should also check the sear engagement surface, verify the guide rod and spring are matched to your use case, and ensure the slide stop and disconnect are functioning correctly. This is a build-for-performance part, not a drop-in fix for a worn or poorly tuned pistol.

Includes hammer and strut only. Installation tools and additional internal components are not included.
