Atlas Custom Works Tornado Aluminum Outer Barrel for Hi-Capa 5.1 w/ 11mm Threads, Black

The Tornado is Atlas Custom Works' outer barrel for the Tokyo Marui Hi-Capa 5.1 platform. If you're running a Hi-Capa and want to swap out the factory barrel while keeping the slide profile clean, this is a straightforward upgrade.

Material and fit. Machined from aluminum, it fits the TM Hi-Capa 5.1 slide. The fit is designed to be drop-in, and it maintains the proper barrel protrusion for reliable hop-up function.

Thread spec matters here. This barrel uses 11mm threading, which is the Hi-Capa standard. That's different from the 14mm CCW you'll find on most rifles. If you're shopping for a compensator, suppressor, or mock suppressor, make sure it's 11mm-compatible or you'll need an adapter.

What you get. The package includes the outer barrel only. It does not include an inner barrel, hop-up unit, or any internals. You're replacing the exterior shell, not rebuilding the whole thing. If your goal is a longer effective range, you'll need to pair this with a quality inner barrel and hop-up setup separately.

Color. Black finish.
