AR15 extended buffer tube for jr carbine?

[Kevin1996]

Hello, I just purchased a JR carbine and would like to install a new buffer tube. The company makes it very clear that the buffer tube needs to be within 1/8" internally of the factory buffer tube, which measures 8 1/2" internally. I believe AR15 buffer tubes are about 7 1/2" internally if I'm correct.

Can anyone help my find a buffer tube to meet the requirements of 8 1/2" internally please. Also, ordering from the company directly isn't an option because I live in NYS

Just to be clear, I'm talking about the buffer tube type with notches for an adjustable stock

You can buy/make spacers to go at the back of the tube to get the correct length. Install them before you install the spring.

I understand that, but it seems that most are too short, not too long

You can use any buffer tube you want as long as you use the correct buffer in it.
