This is an AR10 buffer tube slightly longer than a carbine tube for use in a 308 with a standard 3.25 inch buffer. Same size as an A5 buffer tube.
The Armaspec AR-15/AR-10 Stealth Recoil Spring will work with carbine length buffer tubes. The Spikes Tactical Buffer Tube - .308 is 7 7/8" long which is slightly longer than most Mil-Spec carbine length buffer tubes. I recommend contacting Armaspec to confirm compatibility of the Armaspec AR-15/AR-10 Stealth Recoil Spring with this buffer tube.
This Spikes Tactical Buffer Tube is compatible with Spikes Tactical's .308 buffer spring. It was designed specifically to be used in this buffer tube, and can be found by using the following link:

No, it will not.
A mil-spec carbine buffer will work with this tube. You will need a 308 buffer spring for it though.
This buffer tube has a mil-spec diameter and will fit mil-spec stocks.
I built a spikes tactical 9mm and used a spikes ar 15 buffer tube and spikes 9mm buffer with a flat wire spring. Works great in my set up.
This buffer tube is the roughly 7.75" in depth.
Yes, it will.
