Best mags for the money - Hexmag SR25/AR .308Win 10 Round Rifle Magazine

A magazine is a magazine so it's only important whether they function correctly or not. I have never had a hexmag fail with any caliber I use or in any rifle I use it with. The 308 version is no exception to this, it functions flawlessly and the follower engages the bolt catch on empty every time. My only gripe is that the these fit very tight in the Aero M5 lower, a little sanding loosened it up a bit but still a tight fit and the mag won't drop free. I shoot from a bench so fo me it's not really an issue but is something to be aware of if you plan on building a 308 platform, particularly a carbine.
