Buffer tube length by Jim, Verified Owner, February 2, 2022
This is 7 3/4 inch deep which is required for an AR-10 308. It is also made well and a stock like daniel defense fits tight and slides nice. The bolt will Cycle and the bolt catch will work with the extra length.

excellent fit and finish by JCVd, Verified Owner, April 9, 2020
Found the VLTOR extensions hard to find. The V Seven and Dark Hour Defense units were available. The DHD pice has a great finish and improves the VLTOR A5 RE with anti-tilt lips for the carrier. Great price for a great piece. Would buy again.
