6.5 Grendel Upper Features
Here are some 6.5 Grendel upper features to consider when choosing one.
Forged – Most upper receiver from manufacturers are either forged, machined or cast. The standard is a forged upper receiver. Forged metal retains more strength than other types.
Customization Friendly – Choose an upper that you can switch out barrels and have space for your optics. Most upper comes with a barrel and a handguard. This combo can save you money.
Forward Assist
This was something that I had taken for granted while in the military. Now as a Joe citizen, having forward assist on your AR is good to have for cycling malfunctions.
For these precision shooting at 400 to 600 yards get yourself a 16″ or 20″ barrel with these uppers.
