The 6.8 SPC (6.8x43mm) was initially
developed by MSG Steve Holland and Chris Murray a United States Army
Marksmanship Unit gunsmith to offer superior downrange lethality over the 5.56
NATO/.223 Remington in an AR pattern service rifle with minimal loss of magazine
capacity and a negligible increase in recoil. The 6.8 SPC is also capable of
outstanding accuracy and reliability.
match-grade, Spec II chambered 16 barrels, The 6.8 SPC is capable of pushing a
.277 caliber, 85gr bullet to over 2900 FPS. 110gr bullets easily achieve 2500
FPS with factory loaded ammunition. Appropriate hand loading can achieve even
higher velocities and enable the use of heavier projectiles up to 130 grains,
which dramatically improves terminal ballistics over a 5.56 Nato/.223 Remington
at long range. This added ballistic performance makes the 6.8 SPC perfect for
home protection and SRT/SWAT teams. The 6.8 is a truly ideal hunting round for
medium to heavy game and turns the AR into a serious hunting rifle.
The 6.8 SPC
will require a 6.8 caliber specific bolt and magazine for reliable function.
