Good...but - Strike Industries AR PDW 9mm Buffer

First, works great with 9mm and the shorter pistol buffer tube that's just over 5". It takes some effort to get it i n the 5" tube however, it's worth it. NOW THE BUT.....YOU CAN'T BUY IT WITH THE 5" BUFFER TUBE. So if you want this, you MUST buy the full regular AR15 Short Pistol Buffer Tube package and then buy the 9mm buffer and spring. Being forced to pay double and being left with an unnecessary 5.56 buffer and spring feels like being taken to the cleaners. COME ON Srike.....do right by your customers and fix this package. Disposable $$$ isn't a thing these days...so only 4 stars for a 5 star item because over paying is :(
