Hi DL
If you handle a new Jager sporting arms moderator you will see it is very simlar to the A-Tec with one or two of the A-Tec weakness ironed out. The big difference is the price, the Jager sporting arms one is only £175 this is about £100 less than the A-Tec. The baffle stack is all stainless steel on the Jager one with the body being aluminium. I believe that Titanium baffle stacks will also be available at an extra cost in the near future.
8 to 9 years ago I thought the T8 was the best moddy out there, then for a while the PES was king of the hill, but like in a lot of things time moves on and improved and or better value produces come available.
I recommend this moderator because it has a stainless steel baffle stack to resist corrosion, aluminium body for lightness and it conductive properties, it is a overbarrel design so it upset the rifles balance as little as possible, it is at least as effective in sound reduction as anything else, it is made in the UK and cost less than most other moderators out there.
I think they are at least worth looking at, before anybody spends there hard earned cash on something they may latter regret.
Best rgds
