ATF letter stating that the Magpul AFG is legal for use on AR pistols

Please treat this as reference material only and not legal advice. The ATF does not always adhere to letters, states and local governments are doing their own thing and it’s hard to say what is acceptable or not just to be perfectly blunt. We live in interesting times unfortunately.

Folks, here is an ATF letter saying that an angled foregrip (AFG), such as Magpul’s models, can be used on an AR pistol.  This is the first time someone shared a definitive letter with me vs. hearsay.

12/14/2014 Update:  Here are scanned images of two different ATF letters saying AFGs can be used on AR pistols because they are not considered vertical grips:


This is a second letter wherein they answer a number of good questions about AR pistols in general.  On page three is another comment that the AFG is allowed:


The reason this matters is that a vertical foregrip is not legal without first registering the pistol as an “any other weapon” or AOW.  I recommend people print and keep copies of letters just in case they need to show someone that some aspect of a weapon was “approved” by the ATF at some point.  Just bear in mind that ATF letters are not absolutes but it helps to have them handy if asked.  A state or local government may have their own more restrictive regulations as well so this may not mean AFGs are legal for everyone everywhere.
