Impact 737, NBK, 777 and 787 Pre-Fit Barrels
$789.00
We are proud to offer you the best in Pre-fit barrels for the new (and sexy) Impact 737, 777, 787 & NBK Actions. CNC cut stainless match barrels are quickly becoming the standard in pre-fit barrels. Used by top NRL/ PRS competitors, these barrels have redefined how we think about pre-fit barrels today. Thanks to the high-pressure wash system used in our reaming process, throats and the entire chamber itself have never been smoother and free of tooling marks. This means barrel doesn’t need “fire lapping” and it will start grouping right away! We use only top-quality blanks that are all inspected by use of a Borescope before your blank is cut.
