Can you put a carbine length buffer tube on an AR pistol?
Table of Contents
Can an AR pistol have a standard buffer tube? It can, but you need to watch out for constructive possession. Some builders wrap paracord around the tube so a butt stock can not be installed. And this should be done before installing the pistol upper.
Can you put a rifle buffer tube on a pistol?
Pistol Buffer Tubes When using a barrel shorter than 16″, you must either have a registered lower receiver or a lower that has been converted to a pistol. Using a short barreled upper receiver on an unregistered lower receiver with a rifle stock is against the law.

Are pistol and rifle buffer tubes the same?
The difference between pistol and rifle buffer tubes you ask? Simple, on a pistol buffer tube there is nowhere for a stock to mount. That’s it. Hell, the Thordsen buffer tube kit uses a keyed stock exactly like a rifle stock except that it does not have holes in it for a stock to lock into.
What buffer tube do I need for an AR pistol?
If you’re building an AR pistol with a pistol-length gas system, you will want to stick with an H2 over an H or carbine buffer, though felt recoil may be high. The H2 buffer may fail to fully cycle in a rifle made to shoot subsonic 300 blackout, even with a pistol gas system equipped.
What is the best buffer weight for AR pistol?

The second tier of heavy buffers is ideal for mid-length gas systems, though it’s common to find up to 4.7 oz buffer weights in pistol builds with under 16-inch barrels to reduce violent cycling. If you fire 5.56 NATO, a tier 2 buffer weight is ideal.
What buffer tube do I need for a pistol brace?
The cavity of the brace is ideally suited to buffer tubes that are 1.1” to 1.25” in diameter.
Can I have a stock on AR pistol?
An AR-15 pistol is a pistol-length AR-15 with no stock (only rifles have stocks). In place of a stock, an AR-15 pistol usually has a pistol buffer tube or similar piece that does not allow for the attachment of a traditional stock. To qualify as a pistol, there must be no vertical foregrip.
Can I put a rifle stock on a pistol?
Yes, unless the barrel of the pistol is at least 16 inches in length (and the overall length of the firearm with stock attached is at least 26 inches).
What buffer AR pistol?
What is an AR – 15 buffer tube?
When Eugene Stoner designed the AR-15, the buffer he used was the rifle variant, 6 inches long. The original buffer tube it was housed in is significantly longer than the modern carbine version, at 9.625 inches versus 7.625 inches, because it was meant to be used within a fixed A2 buttstock.
How many different length buffer tubes are there?
While all dire AR rifles function similarly with this system, there are mainly two different sizes of buffers (rifle length and carbine length). The important headline here is that these two sizes are NOT interchangeable. Rifle length buffer weights are used when a standard A2 buffer tube is installed for a fixed stock.
What is the length of a pistol buffer tube?
These buffer tubes measure 1.145 to 1.150 inches in diameter, while the commercial buffer tubes are a little bit wider. Thus, Mil-Spec buffer tubes have slimmer profiles. Other features include a flat back, as opposed to the slanted back of a commercial tube, and the use of different metals in their construction. Note that these features vary.
What is the length of a rifle buffer spring?
Moving on to springs…Standard buffer springs come in two types, Carbine and Rifle. Carbine springs should be between 10.0625 inches and 11.25 inches in length, with longer springs offering more return power. Rifle springs are between 11.75 inches and 13.5 inches.
