maddmacs o-ring lockdown®

The new MaddMacs O-Ring LockDown® is another innovative design from MaddMacs Precision Tactical to reduce compensators from working loose while shooting.  Using a Viton® 90A O-ring, when your Super Comp is tightened to your barrel, the O-Ring creates a seal that will keep the comp from backing off the threads.  Combined with the indexable insert, the new MaddMacs O-Ring LockDown takes 22LR comps to another level.
