I've been digging further and I'm considering the Vortex Viper 4-12x40 or the Vortex razor which is really nice! However, I've found something I really, really like... the Weaver Superslam 4-20x50, but it's more than I wanted to spend. I had a look through one the other day and the clarity and the build quality was spectacular. Whilst the objective is 50mm, which is bigger than I wanted, I'll put up with it.

The 1.5-6x24 is really nice as well!

Tomo wrote:+1 for Vortex scopes - for the money I think they are hard to beat (look nice too!). I love my MRAD scopes - no faffing about having to convert Mil into MOA or anything like that! Just shoot a group, adjust using the reticle and hey presto! on target (wind allowing!)
Here's the Viper 6-24x50 MRAD ffp on my .308 Remi
and a Vortex 1-4x24 TMCQ MRAD scope on my AR.
The .308 shot this group last Saturday @ 100M on Short Siberia
10 rounds (.168g SMK- 41g TR140, PPU brass, Federal 210 primer) I deliberately pulled the last shot right as I was getting worried I wasn't hitting the target! (target is in 1" squares)
The .223 shot this group with some experimental .77g SMK handloads (the targets 3" wide)
Not too shabby using just a X4 scope no bipod (just resting off my elbows).
