Measure the barrel threads - if it is longer than 0.4", you will need a spacer unless you are getting a Surefire Ryder that indexes off the muzzle (or any can that indexes off the muzzle and not the barrel shoulder).

Here's AAC's thread spec guide. The rimfire spec is the first drawing.

If your threads are within the range, then no spacer is needed.
