Custom-Quality Set Ready For Fitting To Deliver Outstanding Accuracy
Premium-quality, .45ACP barrel is precision machined from solid 416 stainless steel barstock to tolerances +/- .001" or less in critical areas. Heat treated to Rc 40-42 to maintain those dimensions, even under the battering of hard competition. These unramped barrels are broach rifled with a left-hand 1-16" twist. Some fitting required, so you can produce a tight, no-play fit for maximum accuracy from your gun. The match grade bushing is machined from the same premium-grade stainless steel, with I.D. and O.D. left slightly oversized to allow custom fitting to your barrel, further ensuring precise lockup and excellent accuracy.
