For use with rifle buffer spring, A5 length buffer (or equivalent) on an AR-15. This is not a standard carbine buffer tube.

The 8" internal length allows a rifle buffer spring and a longer and potentially heavier buffer. The longer buffer system mimics the less-finicky original AR-15 rifle length buffer + tube setup, but in a shorter package. This "opens the operational envelope" -- that is, it puts the spring's force is more consistent through the cycle, creating a smoother cycle and allowing the system to tolerate other parts being further toward the limits of their specifications.

All that said about the A5 buffer system, this specific buffer tube is a quality blue-collar solution. The anodization is thick and hard matte black. The inside has the appropriate dry-film lube coating. At the inside the base of the tube, there's a puddle of this coating, but it doesn't affect function. The manufacture and finish are excellent.

There's a few places where this product could contain some simple user-friendly design upgrades that other A5 tubes come with standard.

While I understand BCM prides it's self on high quality milspec parts, meaning whatever they sell will be the best original MILSPEC, I would have expected the buffer tube for this systen to have had a buffer pin retainer notch since this is not milspec and is more of a novelty item. The retainer notch would have made alignment during installation a breeze. Every other A5 tube I have bought is notched and is half the price. The inside of the tube was also extremely gritty/rough and had to be polished. I do not recommend this tube. There are better A5 tubes for half the price.
