Transitioning from the ACOG optic to the RTS proved to be instinctive for the author, requiring a simple cant of the rifle.
We’ve all heard the phrase about how life sometimes imitates art. Does tactical sometimes imitate sport? We’ll soon find out. The wildly popular “3-Gun” matches have spawned a number of new technical innovations in shooting gear and firearm accessories, perhaps the most unique being Canted Back-up Sights, or CBS for short.
Canting the rifle for close encounters is not a new technique. Soldiers and Marines learned years ago that their full-length M16A2 rifles were a bit long for tight quarters, particularly when maneuvering through buildings. To “shorten” the rifle for CQB they would simply cant the rifle ninety degrees and rotate the stock up and atop their firing shoulder. For shooting across the room or down the hall, aiming along the barrel proved effective enough.
Three-Gun matches include rifles, shotguns and pistols. The rifles or carbines are used for both distant and close-in shooting. Fast and accurate rifle shots out to distances of 300-plus yards are normally accomplished with medium-power optics in the 4 to 5 power range. A 4x ACOG optic is a great choice from mid-range shooting. However, rifles are also called upon for close quarter engagements. The question became how do you burn down near targets as fast as possible while maintaining distant shooting capability?
