I wanted to replace the T8 on my .270 stalking rig with something a bit lighter and the Thirdeye Spartan popped up on the radar.
Initial investigations looked good so I went down to EVO engineering to pick one up.

Craig the owner of EVO/thirdeye is a keen stalker and a bit of an engineering whizz by all accounts. He was just reviewing an article on on a buggati W16 motor that had some of his parts in when I turned up

The mod is a very nice bit of kit, and appears very well thought out. It is both shorter and narrower in diameter that a T8, weight is about 250g's lighter.
This doesn't sound much but when fitted to the rifle it makes a big difference both in terms of handling and carrying on a sling. The rifle no longer feels muzzle heavy!

The mod is made from Aircraft grade alloy and is fully stripable. A neat key is provided for this purpose.
Starting at the muzzle end is an over barrel bush (a non overbarrel version is available) and a stainless muzzle brake type baffle arrangement which is designed to reduce recoil.
There are then a series of alloy baffles, all of which have stainless inserts to prevent gas cutting and improve longevity.
The muzzle cap also includes a baffle and expansion chamber.
