308 Mags ?

[Sak007]

What are the best SR25/AR308 mags for loading out a cartridge as much as possible that aren't Kac priced ? Iv'e looked at the Lancers & Larue's but neither list the id of the mag so any help would be appreciated .

One of the reviews on Larue's website listed the interior of the magazine at 2.870

For reference, the 25 rd pmag lr/sr is listed as 2.830" max oal.
