Shore Tactical semi custom premium line upper in 20″ 223 Wylde Match.
Semi Custom means that this upper was assembled with options usually reserved for our custom builds and extra time put in to insure this upper will preform above expectations.
To begin each stripped receiver is lapped to insure proper straightness with barrel fitment to the extension. Once fitment is complete feed ramps are matched to each receiver and polished. This means a glass smooth transition for each round from magazine to chamber. The extensions are then bedded to each receiver and barrel but torqued to spec. Gas blocks are check with bore score for alignment after install.
Bolt carrier groups go through inspection for clean operation. gas key bores are check along with smooth firing pin operations. Fire pin protrusion is measured and adjusted if needed to insure proper ignition avoiding ligh primer strikes.
All uppers are life test fired and cases are included with owners information and warranty card.
