Item Installed: Rail Mounted Forward Back Up Iron Sight (BUIS)



Purpose of Item: Iron sights have been supplemented by a broad variety of optics, both electronic and magnified. However, any serious weapon needs to retain some form of Back Up Iron Sight (BUIS) in case of optic failure. Anyone who has had an optic failure in a real world event becomes semi-religious in their convictions, or at least I have.

There is a debate between some persons regarding the use of a BUIS mounted to a rail. One group of people claim that a barrel mounted front sight will retain a higher level of accuracy due to its mounting on the actual barrel, instead of a secondary piece of equipment. While I don't discount this theory, I feel that it overlooks something that is more important, which is overall reliability of the weapon system.

Being able to hide a gas block under a rail protects it from getting knocked out of alignment. This increases overall system reliability. While there are BUIS variants that are pinned into place through the barrel, they are the exception, and not the norm. Secondly, pushing the front sight out farther on a rail, increases the sight radius, which typically allows for more accurate target engagement.

While I can understand both sides of the arguement, my own experience involved a distance of roughly 25 yards with an armed suspect coming out a window. Reliability, and rounds on target will always be more important than claims of accuracy. After all, if you are using your BUIS, the threat most likely isn't out far enough that you are trying to figure windage or elevation.
