As the saying goes, the devil is in the details, and with AR-15 rifles and carbines a small tweak to, say, the trigger can mean the difference between a hit or a miss. Swapping in a larger charging handle will mean you can clear a jam more quickly and effectively. Single-point slings may have been born for battle and protecting the streets, but they are well suited for still-hunting with an AR.

It’s these finer details that can help a shooter, hunter or home defender put the finishing customizations on their firearm for optimum performance and shooting comfort.

Here’s a look at some support gear to keeping your AR running smoothly.

The BCM Gunfighter Quick Detachable KeyMod Sling Mount is a low-profile mount that fits standardized KeyMod interface mounting holes. Standard push-button swivels are used, providing an eight-position attachment point that is flush with the surface, eliminating snags. When mounting, arrows locate the forward portion. An included Torx wrench tightens the two mounting screws after the assembly slips into place on the KeyMod. (bravocompanymfg.com; 877-272-8626)
