I came across the atec wave early this year. I think it cost £28 new. It looked well made, compact and lightweight so thought I'd try it out for my semi auto rimfire. And I was really Impressed. It was much better than the sak it replaced. I'd say not only was it smaller/lighter it was also quiter. Aesthetically it was better aswell. The sak is known as a good all rounder, now I'd say it's the atec. I'm not sure it comes apart like the sak does though Wich isn't big issue .
