20" 6.5 Grendel 1/8 15" TLN Rail Upper (Quick Ship)
A 20" 6.5 Grendel machined from Mil-B Spec 4150CMV and melonited delivers the accuracy potential of this cartridge in a lighter weight package ideal for hunting and mixed range tactical engagements. The flat trajectory, high feet per second of the round lends itself to hunting medium game or tactical situations at range.
When ordering please note that the 6.5 Grendel requires a 6.5 Grendel bolt for proper headspacing (5.56mm & 7.62x39mm BCGs will not function properly).
