AKAH 3-12x56 LA

Excellent, chunky, bright, positive clicks, holds zero and great value for money.
It's literally a poor man's Schmidt & Bender, as AKAH used to be associated with S&B. It's not a Schmidt, but for 99% circumstances, you're unlikely to notice the difference.
It's stood up to many rounds of 300 Win Mag, and not shifted zero ; so for about £300, there's little to complain about.
I definitely recommend it. **
