🔬 Does a ar pistol need a buffer tube?

I will be writing more about specific questions regarding this topic but as for today’s question … per the ATF Firearms Technology Branch, so long as the receiver has never been transferred or configured as a rifle and therefore is eligible to be configured as a pistol then it does not matter what buffer tube you use so long as you are not in possession of a buttstock that “could readily be installed” on the resulting pistol.

You can buy buffer tube assembly parts and buffer tube kits for self-fabrication in the perfect way. The lightweight AR patterned rifles requires extra weight to deliver optimum performance while shooting with. Buffer tubes are used for various reasons in weaponry such as the AR rifle, to reduce jerks and jolts while firing.

In the AR platform, this spring (and buffer weight) is located directly behind the bolt carrier, resulting in the need for a "tube". Is it a good design? It's a matter of opinion. It's large and clunky and makes folding stocks impossible. OTOH, the buffer weights can be customized for various barrel length, ammo type, and gas system configurations.

That is what started me thinking about why the use of the 9mm buffer length and/or quarters or washers in the buffer tube is needed. The shorter stroke would limit the amount of inertia force created on the return stroke of the buffer and the heavier buffer that the 9mm tends to run could cause more force on the buffer pin.

The use of buffers in rifles, particularly ARs with A1 or A2 stock assemblies, is simple. It’s Hobson’s choice — use the originals, because they haven’t changed and don’t need to be. The rifle buffer is the longer, two-flanged one. The rifle spring is the one with 41 to 43 coils.

The AR-15 buffer tube (also known as the receiver extension), is the metal protrusion that sticks out of the rifle and serves two functions: it houses the recoil buffer mechanism, and it serves as the attachment point for the buttstock.

First, the buffer and buffer spring are housed within the buffer tube, and set the pace for the AR’s cyclic action. After a shot is fired the bolt carrier group (BCG) contacts with the buffer as it moves rearward within the tube and the weight of the buffer and tension in the spring resist the rearward travel of the BCG.

That is a lot of money just to have a folding stock on an AR-15!!!!For that kind of change I think I will deck it out with a 16-20" DI upper and use the left over to start a 16" M14 CQB rifle. ^ IMVHO, the best deal right now for the money is the 14.5" PA'd midlength upper, with a cold hammer forged barrel.

Because the the.308 AR requires longer bolt travel, you cannot use an AR-15 buffer in an AR-15 buffer tube on a 308 rifle. The careful balance of length of the carrier, the amount of travel...

Receiver Extension Tube also know as the Buffer Tube. This is the long black tube that internally houses the Recoil Buffer and Recoil Buffer Spring. Externally the buffer tube secures the buttstock to the rifle. Generally speaking there are two classes of receiver extension tube, Carbine Length and Rifle Length.

The other one runs a carbine H2 buffer with some steel washers in the back of the ...

Does a 9mm ar need a buffer tube for the money?

With the requirement to retain the buffer it will be impossible to build an AR without a buffer tube. Ever wonder why a 9mm BCG has the tail filled in with a big chunk of steel?

I would unscrew the buffer tube about 2mm to just line up the detent in the notch so it moves up and down freely. I suspect it turned a bit when he tightened the castle nut down.

How long is an ar buffer tube?

The correct one to use is determined by the firearm setup (receiver size, buffer tube type, and chambering). Buffer Length. The buffer needs to be the right length so that when the bolt carrier cycles to the rear, it stops at the right position. If the buffer is too short, the gas key can crash into the lower receiver's buffer tube mount; if the buffer is too long, the bolt carrier will short-stroke and fail to pick up the next round.
