Crazy awesome
With the 2 stage system, it can be a little strange to get the bolt manually locked to the rear. But the advantages in recoil reduction/dampening are ridiculous, personally 100% worth it. If you wanna run a standard bcg in comp with a captured buffer, this is the one for you.
USNot worth the money, you have to barbarian the charging handle to chamber a round
Terrible overall operation. Great design. Just not for the average shooter.
