    They definitely do the job. Thank you.

  2. Jeff Meyers (verified owner)

    Makes the job of timing the teeth/slots of the barrel nut with the gas tube markedly simple, and still tighten the nut to specs. Purchased several units to have on hand and discovered the total count did not add up correctly. Customer service was great and they rectified the problem immediately.
