Action Army AAC-C1 CO2 Power Chamber

The Athena runs on gas or CO2 through a power chamber, and the chamber is where the rifle’s character is set. Swapping it is how you move the platform between ratings without touching the rest of the internals.

Two ratings are offered. They are the manufacturer’s own parts for their own rifle, which matters on a platform this specific: the Athena is not a VSR underneath and generic bolt action parts do not transfer to it.

Action Army rate the complete rifle at no more than 1.9 joules depending on batch and version, and that figure is for the rifle as a whole rather than for a chamber in isolation. Chrono the result.

Specifications

Good to know before you buy

Chrono it before you play, every time. A chamber change moves the rifle’s output and your site will want a reading, not a part number.

CO2 and gas behave differently on temperature. The same chamber reads differently on a cold morning than it does at midday, so test in the conditions you will play in.

This is the chamber alone. The teflon ring that seals an upgraded chamber is a separate part and we list it on its own.

Athena parts do not interchange with VSR. The AAC-C1 is its own platform, so parts from the VSR side of our range will not fit it.

Frequently asked questions

What is the difference between the M130 and the M150?
The rating. Which suits you depends on your site’s bolt action limit and the ammunition you shoot, so work backwards from the limit.

Will this fit anything other than the Athena?
No. It is an AAC-C1 part and the platform is specific to Action Army.

Does it come with seals?
No seal set is listed as included. The o-ring set and the teflon ring for an upgraded chamber are separate parts we stock.

Can I run gas and CO2 through the same chamber?
The rifle is built for both. Which you use changes the reading, so chrono each.

What output will I get?
Not publishable with any honesty. The maker gives a figure for the complete rifle and nothing for a chamber on its own.
