Silencer Acronym Guide

Silencer Shop Acronym Guide   The firearm world is wrought with acronyms.  Much of this carries over from a strong influence from the military community (who has an undeniable affinity for shortening bothersome things like writing and speaking). The suppressor industry – as a subset of the much larger firearm industry – is not immune to these shorthand abbreviations. In fact, we have some of our very own.  Some basic, some not so basic. Below is a list of common silencer-related shortcuts for your reference.   2A: Second Amendment… The reason that we have all these awesome acronyms 41F/41P: ATF Final Rule 41F – Background Checks for Responsible Persons – Effective July 13, 2016 AL:  Aluminum AOW: Any Other Weapon ASA: American Suppressor Association ATF (BATFE): Bureau of Alcohol, Tobacco, Firearms and Explosives BBL: Barrel BCG: Bolt Carrier Group BIL: Silencer Shop’s Buy-It-Local program CLEO: Chief Law Enforcement Officer COO: Chief Operating Officer… We love you Gary.

    My favorite acronym from my military days – we’d gotten a new post commander who was not familiar with all the post’s acronyms. So, after a couple of weeks he sent a memo out to everone on post. The contents read “DUA”. After a few days a junior officer finally had enough to drink at the Officer’s Club to ask the general what DUA meant. The general replied, “Don’t Use Abbreviations”.
