Our Selection 12 Best 6.5 Magazine Extension – Editor’s Choice
To get the great performance of the rifle, all parts should be built quality, and magazines are not exceptions. This understanding comes after some unpleasant mags’ malfunctions, such as warped aluminum or worn springs. The 6.5 Grendel is some kind of niche cartridge. There is no such wide range of mags for 6.5 Grendel as for the 5.56 and the 7.62 NATO.
Why do we need 6.5 Grendel Mags?
The 6.5 Grendel is a low recoil long-range cartridge engineered particularly for the AR-15 rifles to present reliable ballistics use. The AR can be converted by swapping the upper receiver for a 6.5 Grendel Upper, as the Grendel 6.5 can be used with an existing 5.56 lower receiver.
