Airsoft Canada - View Single Post - Hi-capa nozzle and cylinder tolerances

Hey guys,

Greeting and a happy newyear to You all.

I run a modded tm 5.1 Driven by Hpa AS my primary in 3/4 of my games.

It has a uac blowback unit and uac nozzle, i love the feel of that product, But What i dont like is its tolerance between its cylinder and the nozzle.

It does NOT provide a Good airseal. Fps is low and consistency is worse than if i use standard bbu and a nineball cylinderhead with the same uac nozzle.

The o ring is too small, and i havent been able to find the right oring size yet.

Does Anybody Know What size i need for a tight fit?

If NOT Then id like to Know if any compagny make a light Weight bbu where i Can change cylinderheads instead of the fixed head on the uac?

What bbu would You recommend in a money no issue Hicapa build?

Best regars

Ben
