Our new 3rd generation of Top Notch clone barrels are shipping and are the best around. They are milled on a state of the art 4th axis lathe. This machine holds the critical tolerances to +/- .0005. The barrel blanks are stainless, so they will not rust. The finish we used on these barrels is the same finish used by Sig on all of their slides and 556 barrels. The unique process gives an incredible look without adding any dimension. This finish gives the barrel a Rockwell 70 surface hardness and is more corrosive resistant than phosphate. These Top Notch clone barrels meet the factory specs and except all factory attachments.

BUYER BEWARE OF WHAT YOU ARE BUYING

When you come across a aftermarket barrel that is shinny on the back end, the area that slides into the receiver and makes contact with the upper, this is the sign that the barrel was OD (outside diameter) ground after the barrel was finished. Despite what they may say the tolerances were not held in the machining of these barrels and therefore they were to big and would not fit into the upper receiver. After the finish was installed they were OD ground exposing bare metal. Now you have a very high probability that the barrel can rust into the receiver! BUYER BEWARE! Buy from Top Notch with confidence. We stand behind and guarantee all of the parts we make.

New barrels are being turned now. We expect to have them back in stock July 1st, 2009.
