2A Armament 8 Position Receiver Extension Buffer Tube For AR15 Style 5.56/.223 Rifles

This billet aluminum and carbine length buffer tube is manufactured to the same high 2A Armament standards and finished with hard anodize for lasting performance. The 2A Armament 8 position buffer tube is not any longer than the common mil standard 6 position buffer tube. The overall length from end to end (uninstalled) is 7.5 inches. This item ships as the buffer tube only.

Features

- Extended positions, increment adjustments have a finer spaced length of pull
- Mil spec extension diameter of 1.148 inch, and thread diameter of 1.185 inch
- Carbine length - compatible with standard buffer springs, no spacer(s) needed
- Extended carrier support flange that supports the carrier for better anti tilt performance
- Self aligns with the buffer detent
- Chamfered edges on the stock guide ramps for better feel
- Overall length: 7.5 inches (uninstalled)
- Vented
- Weight: 3.65 ounces

Q: I have a similar tube, but when it is installed so that the notch is fully engaged around the detant, the top of the tube sticks out past the threads. This stops the upper receiver from closing. Does the 8 position tube solve this problem? Thank You

Asked by: Bradford - 1/1/2020

A: Bradford, the 2A Armament 8 Position Receiver Extension Buffer Tube is made to exacting measurements. We've sold a lot of these buffer tubes and nobody has ever even communicated to us that the 2A tube was anything less than perfect. Buy this buffer tube with confidence that it was made to the correct dimensions. Thanks for the inquiry.

Q: I have 2 out of several A/R style rifles & pistols that have "COMMERCIAL" buffer tubes on them. Can I simply swap my commercial tubes and go to Mil Spec? I'm having a difficult time finding stocks for the commercial buffers that are suitable for the use of the gun. Thanks

Asked by: James - 11/4/2019

A: Yes, it's that simple. Seems more and more are going the mil spec route for the reason you mention. Thanks for the inquiry.
