We also had an opportunity to test the PWS Enhanced Buffer Tube and I agree with the review by MoxyDave. We tested the cheaper version. The machining was high quality, the finish looked flawless, and the fit was great! PWS found a way to make a standard buffer tube a little more useful by providing some much needed features. As stated above, the difference in appearance between the forged (more expensive version) and the impact extruded (cheaper) version appear almost identical. Without having tested the forged version I would hate to draw conclusions but I would assume the forged version would probably provide an increase in both strength and rigidity.
