The Radical Firearms 20" 6.5 Grendel Upper Receiver Group is a great way to have a fully custom upper at off-the-shelf prices! With 6.5 Grendel's longer effective range, flat trajectory and bullets, this caliber is well suited to deer and varmints. The caliber has also shown interest in the Serbian Army, as well as some US Special Forces units. When compared to 5.56 NATO, 6.5 Grendel gives you the potential for twice the mass fragments all in a package that shoots flatter, with 50% less felt recoil than 7.62 NATO M80 ammunition. This upper makes for an excellent upgrade to your existing lower, allowing you to take advantage of the benefits of 6.5 Grendel.
