The Krieger is one of our nicest all around builds. Geissele 16" CHF CL barrels are the heart of the build, bringing truly top tier durability, accuracy, and shootability in a do-it-all length. CMT 7-sided Mlock rails provide a rock solid attachment for any and all accessories you could ever want. In the back end of the build we have AO TMS BCGs and the Breek ambi charging handles.

Barrel nut is sequentially torqued down to 50 FT-lbs. Starting at 25, then 35, and then finally 50 FT-lbs to ensure proper mating of the threads. 
 
Barrel is also bedded to the upper receiver with an expanding/hardening compound to ensure perfect fit and reliable accuracy. 
 
If you legit burn out a barrel, like 10,000 -25,000 rounds, and the barrel becomes inaccurate I will rebarrel it for you for free. Good luck.
