![]() ![]() There are various island-type rear open sights that move up, down and sideways on dovetails and are fixed in place with set screws. When confronting a dangerous animal at close quarters, with the need for a flurry of shots, having your sights go wonky in mid-barrage is definitely undesirable. Severe recoil will sometimes move anything movable. While we are on the subject of sights that fold up or down and employ spring pressure to hold them in place, some deluxe rifles have front sights with or without folding hoods or large beads that can be raised for use in low light. Most hunters who buy rifles with express sights don't shoot them enough with the blade raised to see if this is a problem. Recoil can cause a raised blade to flip back down, and remembering to check this in the heat of the moment is a bit much to expect (much like the moving elevation blade on the High Wall mentioned above). These arrangements are great in theory, offering settings out to several hundred yards, but in practice they may not be so good. Open sights are standard, often with a quarter-rib and a selection of folding blades (the "express" sight). One place you see iron sights in common use is on a double rifle or bolt action for dangerous game. At these ranges, you have time to settle in and aim. At these ranges, you will likely be shooting quickly at an alert animal, and speed will be more important than pinpoint accuracy.įrom 100 to 300 yards, which is stretching the practical limit for iron sights on a big game rifle, a receiver or tang sight with an aperture is more exact. The sight adjustments may be crude and awkward, but once they're aligned they work. On big game out to 100 yards, no system is better than the basic blade or bead combined with an open sight on the barrel. ![]()
