Re: AR Pistol vs AR SBR - Which Is The Best Choice?

300 AAC Blackout 150gr bullet at an average of 1750 fps' from a 10.5 inch barrel. Seems reasonable.

Re: AR Pistol vs AR SBR - Which Is The Best Choice?

The AR pistol is a rifle with a short barrel; however, the law in this case works in our benefit by categorizing this AR configuration as a pistol. The buffer tube on the AR pistol is an integral part of the weapon and necessary for function; therefore, it is not a stock. An AK pistol, the Kel-Tec PLR16, piston AR pistols, and similar designs do not have this feature and as a result it is difficult or impossible to get more than two points of contact when firing.

The main plus for the AR pistol is that it is light and compact yet provides the power and range of a rifle. Since it is not an NFA controlled item, you can take it anywhere a pistol is legal without additional ATF permissions. It breaks down into a package that fits easily into a daypack or small duffle so you could carry one if you wished. Forget the arm brace unless you truly need one. The brace is not necessary to shoot the pistol accurately, adds weight, and is tempting to shoulder and therefore a shiny object for unwelcome government attention.

It is very easy to get a good cheek weld with the buffer tube and thus create three points of contact (rubber cover not necessary, but is does add some cushion). You can then manipulate and fire the pistol like you would a rifle. If you have a red dot sight, the buffer tube cheek weld positions your eye behind the sight just as a stock would on a rifle.

The 5.56 round from a short barrel is unpleasant to say the least. However, the 300 Blackout with a pistol length gas system is much milder and the cartridge is very versatile. There are a number of commercial loadings; however, reloaders can make their own brass and it is easy to reload. It will handle bullet weights from supersonic 110gr up to subsonic 220gr and everything in between. There is a lot of load data available and many loads use pistol powder (e.g. WW 296). Loads with pistol powder certainly reduce the amount of unburned powder flashing into the air and I’ve not noted them to be any dirtier than any other direct impingement system.

For years I turned up my nose when I saw one of these—then I shot one.
