We all know that guy. You know, the one whose first AR build looks mall-ninja killer, sporting a gadget-laden quad-rail with barely enough room left to grip it. But, it doesn’t take long until the jagged edges of the Picatinny rails on all four sides cheese-grates his hand. Fortunately, plenty of companies now make fore-ends that offer both comfortability and customization. The 14.5-Inch 3RGS Handguard from Brothers & Arms USA is one good example. With a single Pic rail at the top, this handguard features a patent-pending design with a smooth ergonomic body and — depending on which system you pick — multiple M-LOK or KeyMod-compatible attachment points, so you can affix the accessories you want where you want. The handguard comes with a proprietary barrel nut and has a 1.36-inch diameter.
