Only 1 left in stock
Manufactured by our finest domestic Mil-Spec contractors these are among the best 6.8 SPC AR rifle bolts on the market and the same bolts we use as the basis of our renowned custom rifles!
Our bolt is precision machined from aerospace grade 9310 tool steel, shot-peened for increased strength and includes a tool steel extractor and ejector, appropriate extractor spring, and is MPI (Magnetic Particle Inspected) and randomly batch HPT (High Pressure Tested).
The extractor is 4140 gun quality, annealed, cold drawn steel per the Mil-Spec.
The 8620 steel carrier includes a properly machined Mil-Spec gas key that is completely Nickel Boron plated for the ultimate in smooth operation and easy cleanup. It is secured to the carrier via Grade 8 fasteners and properly staked in our shop during final inspection.
These precisely machined, finished and hardened parts will ensure long term proper gas system functioning and reliability.
All experienced AR shooters know that the best spare parts kit for an AR-15 rifle is a spare complete bolt carrier assembly!
NOTE- The only difference between “semi-auto” and “full-auto” carriers are the carrier weight and external profile. The “full-auto” carrier is slightly heavier to provide more mass and lower cyclic rate that can benefit carbine length and shorter gas systems, short-barreled/suppressed rifles and machine guns. The “semi-auto” carrier is slightly lighter to provide the least amount of recoil impulse for rifle-length gas systems and its design makes reinstalling the firing pin easier after cleaning.
Both carrier types are considered completely interchangeable and there are no restrictions on the ownership of a “full auto” carrier group in a semi-automatic rifle.

Wilson combat 6.8 spc review
This does not work, very disappointed. This carrier group has no markings on it to identify the caliber and is jamming after every shot. I purchased the mag and bolt carrier together 6.8 spc Wilson. I even changed mags and ammunition. This is garbage!
