All I can say is HOLY CROW is this guy a talented brilliant builder! My TKO for my NON QE Hatsan AT 44 showed up today and the rifle went from sounding like a .22 rimfire to a dull quiet little thump. I had a chance to shoot a QE AT44 and this is quieter. The TKO threaded on perfectly and alignment was perfect. The carbon fiber wrap looks amazing and it got here in a timely fashion. (wow USPS got one right). I had an air stripper on the rifle originally and this replaced it and only added about 2 inches. I'm in love with this LDC!
