Precision machined from tough, stressproof steel with square-profile fingers that grip the sight notches firmly and won’t “roll out”; provides easy, exact sight adjustment. Plus, they resist bending and breaking to give years of service. Deeply drilled body fits both issue and tall blade sights. An extra-nice touch are the hex-shaped bodies; they’re easy to grasp, easy to turn and won’t roll off your bench. Three tools: A1 five-prong and A2 four-prong fit front and rear sights. A1/A2 is double ended to fit both five-detent A1 and four-detent, square blade, A2 front sights only. A2 wrenches also fit FN SCAR.
