At 15 pistol could I put a vertical grip on it
Nope, not unless you get a tax stamp.
The ATF has long held that adding a vertical fore-grip to a pistol makes it an AOW subject to the requirements of the National Firearms Act (NFA). To summarize … unless your AR pistol has an OAL greater than 26 inches then you should not add a vertical fore-grip unless you first submit a Form 1 and get it approved.
@Joseph_1970 is correct
Welcome to the family Roger, glad you are on board.
Thanks everyone!! I learned something new today!
You can however put a slanted grip on an AR-15 pistol.
Very true. An angled grip or hand stop is legal.
I actually prefer a small hand stop on short barrels ARs. I feel they help me get the barrel from one target to the next faster/smoother.
Agreed. Even on a rifle or carbine I’ve found a hand stop to be much more useful and comfortable that a vertical grip. I own a FAB defense vertical grip that tilts and rotates however it’s heavy and seems to be most effective in a patrol type rifle set up. Opinions may vary but that’s my 2 cents
The Magpul AFG (Angled Fore Grip) and copies there to are the ones mentioned in the AFTE letter and while angled in the front they are also vertical in the rear. So you can either put your hand “On” the angled part or put your hand behind it to act as a vertical hand stop and still be legal. I tried turning it around but that wasn’t comfortable. Fixed vertical grips are verbotten on pistols.
This is true. The simple hand stop gives me more flexibility as to how I grab/manipulate the muzzle and of the gun and by exerting some forward pressure against it while putting my off hand thumb over the hand guard it helps with mitigating recoil and muzzle rise too.
