This FOX Silencer 300 moderator is a quality Dutch product with very clever engineering, which makes it suitable for high energy air rifles. The moderator distinguishes itself with an inner, completely machined from one piece of high quality aluminium. To be clear, this includes all the compartments, walls, et cetera. The advantage of this is the fact the inner can’t deform by pressure waves and thanks to the smartly engineered chamber walls, there’s no need for damping felt, which, with time, would lose it’s dampening under influence of shockwaves and oils.

Because the internals of the FOX Silencer 300 moderator are machined from a solid piece, which results in quite a piece of art, the moderator only consists of three main

components: the mentioned one-piece internals, the sleeve and a locknut. Between these parts, O-rings are featured to keep everything airtight where it needs to be. These O-rings should be placed with a bit of acid-free grease.

Mounting the FOX Silencer 300 moderator is simple as there are no tools needed, you just screw it onto the barrel and tighten it by hand. As with all products that are mounted after the muzzle, there will be a slight shift in the point of impact. That’s why we always recommend to re-zero your air rifle once after mounting a moderator.

The FOX Silencer 300 moderator has a length of 147 mm and a diameter of 30 mm. It’s suitable for airguns with a maximum energy of 300 Joule.
