I just posted a video showing this gun kit and describing it in detail

This New Custom AEA Zeus 12ga Smooth Bore Choked 19″ shotgun barrel. The overall length with adapter and choke is 19″, the choke is about 2″ of that. The choke is removable if you want a shorter barrel.

The lot comes with:

1. The custom barrel

2. The barrel-to-Zeus adapter

3. The custom choke (Uses Remington inserts).

4. (20) asst. 72cal shotshell rounds

As far as cost goes, keep in mind if you order a 58cal barrel from AEA for your Zeus, it is around 300.00, this is a bunch of stuff for the price.
