Why Guntec USA

Guntec USA is a Scottsdale, Arizona parts maker that's been around since 1989. It carries over 600 parts, all made in the USA, for the AR-15, AR-308 and AR-9.

The range runs from budget lower parts to free float 6061-T6 handguards in black, OD green and FDE, plus Claw flash hiders, flip up backup sights and dress up parts in lots of colors.

Its charging handles run about $42 against roughly $90 for the typical one. Bolt catches cost more than usual, about $42 against $15, and take about 2% of that slot. In early October only about 22% of its listings across stores were in stock.

Colored parts are mostly about looks. We'd buy Guntec for a budget handguard or a color match, and keep the bolt and barrel money for proven names.
