I have yet to see any piece of UTG which I'd actually consider using. Didn't know they were making buffer tubes. With the abundance of quality products out there, not exactly running to get one. The only two pieces of Tapco I generally recommend are their AK trigger and pistol grip. The rest, eh. I've never said Olympics aren't accurate. Many are, however, across the board (speaking of dozens of examples) Olys tend to not be RELIABLE. Wanna kill these ads? We can help!
