These Low Profile Fixed Barrel Adapters are light and fast! Machined of 6061 Aluminum to be lighter and thinner than the original FBA, these bad boys come in at only .4 oz!. The Low Profile is only .65″ overall, adding a mere .1″ to the length of the silencer when in use. The Low Profile FBA is the preferred firearm silencer adapter for lower pressure rounds like the 9×19 or 300 BLK, but can also handle rounds like the 5.56 NATO when used on barrels at least 16″ long.
These adapters are also backwards compatible with all older Mystic and Infiniti silencers.
* Note: The MPX Lo Pro FBA and the 18×1 mm Scorpion FBA have external wrench flats for removal, and add about .5″ to the overall length of the silencer.
