Re: Premier Heritage 3-15 or 5-25
If it is going to go on a LR-308 do not go any bigger than a
3-15x. The 5-25x is simply too big and unwieldy on any AR15/AR10/AR clone. I have gone that route in the past.
My tactical competition rifle (GAP AR10) is running a S&B 3-12 PMII on it and performs very well out to 1000 yards. IMHO I would not want a scope any bigger on it, not even the 4-16 PMII which also jumps up in size. I often tell myself that it would be nice to have a scope that went up to 15 or 16 power on the AR10. But in all honesty and reality a scope larger than a 3-12x is not going to make me shoot smaller groups than I already am out to 1000.
And I am shooting my AR10 almost neck and neck with the bolt rifles with large magnification scopes when it comes to group sizes and scoring.
The AR15/AR10/AR clone rifles do not balance well with a big ass scope sitting on top of them. The big scopes are more manageable on a conventional, wider-bodied stocked rifle.
Not to be a smartass, but I would be more concerned about spending the time and money on ammunition learning how to drive your LR-308 than being concerned with high magnification. The big semi-auto's take a lot of practice to learn how to shoot competitively against the bolt rifles. A high magnification scope is not going to make you shoot any better.
Do not have a pic of a Premier scope on an AR but here is a pic of my 3-12 PMII on my AR10 with a Premier 5-25 in comparison. The Premier 3-15 is approx the same length as the 3-12 PMII
