The quality seems to be there - Obsidian Arms AR-15 Specialty Tool Set

I haven't used this item yet, either, so for many this will be a worthless review. However, I do want to state that the quality of the kit seems to be good enough. One reviewer characterized the "delrin" push rod as not delrin at all, but cheap plastic. I didn't find that to be the case in the kit I received. I won't insist that it is indeed delrin - I don't know - but it certainly appears to be sturdy enough for its intended purpose. I wasn't disappointed in it at all. The entire kit appears substantial enough to do its intended job, and it's U.S.-made! Yes. I'd buy it again.
