Light weight...buffer tube a tad too long - V Seven 2055 Ultra-Light Premium Buffer Kit

Light weight it is. I purchased as part of a low-weight (less than 4 1/2 pounds w/16 in barrel) AR build. Installed it on a 2A Balios-Lite receiver set. The buffer tube extended ~1/16 inch past the inside edge of the lower receiver when installed...sufficient to prevent the upper from fully rotating into position to allow the takedown pin to pass through the upper receiver. Had to disassemble and take off material...shorten the threaded end... with a dremmel. Other than that, it's a good option for a low-weight build.
