Just switch to iron sights and join the Irons! Jokes aside – besides practical shooting and Brutality matches, there are other disciplines where using iron sights is a world of its own. Some also use these as backup sights for rifles, in case the optics fail.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePicatinny mount with a folding mechanism\u003c\/li\u003e\n\u003cli\u003eFront and rear sight adjustments without tools\u003c\/li\u003e\n\u003cli\u003eBDC adjustment for 200-600 yards in 50-yard increments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFeatures\u003c\/h2\u003e\u003cp\u003eThis rifle sight set is intended \u003cb\u003eprimarily for AR-type rifles\u003c\/b\u003e that have at least 21 inches \/ 53 cm of continuous Picatinny rail – or Picatinny rail segments spaced at this distance. The sights are mounted on the rail in the same plane.\u003c\/p\u003e\u003cp\u003eThis Ultradyne sight set features a \u003cb\u003ecircle-to-circle sight picture\u003c\/b\u003e, meaning you aim through the holes in both the rear sight and front post. It’s reminiscent of a more refined diopter system but is a hundred times more field-ready. This way, you can focus directly on the target instead of aligning a blurry post with the bottom of the target or some other similar method.\u003c\/p\u003e\u003cp\u003eThe ballistic adjustments (BDC) of the rear sight are based on the 5.56x45 M193 cartridge, according to the manufacturer – but despite our research, there is no information on specific barrel lengths, muzzle velocities, rifling twists, etc. The truth about your own ammunition or load will be revealed in your own tests!\u003c\/p\u003e\u003ch2\u003eManufacturer's Installation Instructions\u003c\/h2\u003e\u003cp\u003eHere is one way to install the sights on your rifle.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eEnsure that the Picatinny rail is aligned with the barrel. Attach the sights and tighten the screws to a torque of 1.4-1.7 Nm (12-15 inch-lb).\u003c\/li\u003e\n\u003cli\u003eSet the adjustment screw on the rear sight to the \"2\" position. Adjust the windage on both the front and rear sights to the center if they are not already.\u003c\/li\u003e\n\u003cli\u003eGo to the shooting range and fire sight-in shots at 25 yards on a target. Adjust the point of impact using only the front sight so that it is 3.6 cm (1.4\") below the point of aim at 25 yards.\u003c\/li\u003e\n\u003cli\u003e\u003cb\u003eNote: Adjust the elevation of the front sight by pressing the sight down and rotating the post in quarter-turn increments. You don't need tools or force.\u003c\/b\u003e\u003c\/li\u003e\n\u003cli\u003eYour rifle should now be sighted in to hit the point of aim at 50 and 200 yards using the aforementioned M193 cartridge.
