Check back May 2023
18" SPR - NEW lighter weight profile for those that want a faster swinging rifle.  Rifle length gas system to soften the recoil impulse for the fastest follow up shots. Plenty accurate enough for a walking varmint rifle.  None of the military ammo (55,62fmj)is accurate in any barrel but the 77gr Razor core and Black Hills MK262 shoots pretty well. 62gr Gold dots and other handloads can shoot 1/2" MOA.  24.7gr H335 with 62gr Gold dots 2.27" is a known good load.

NOTICE- This barrel has standard 1/2-28 muzzle threads

    DO NOT USE  bullets that are larger than .277" in these 6.8 barrels, 99.9% of all .270/6.8 bullets made are .277" diameter.  The chambers were designed for .277" bullets and all 6.8 barrels have a .277" bore so bullets larger than .277" will cause excess pressure and increased copper fouling.  It seems some Cavity Back bullets are .278" and on top of that they are solid copper so check the diameter of the bullets before using them.
