Allen Engineering Suppressors

If the barrel is too short to properly mount the M4 Collar and has at least 1.5" of exposed barrel, this adapter will add the necessary length. This will also fit on long barrels, but will and about 1" of length.

This adapter adds extended 1/2x28 threads and requires the AEMB Mount to mount the suppressor.

This works with the AEM4, AEM3, and AEM2.
