The Troy QARS 4.2 is a quick-attach rail section built to add real estate exactly where you want it on your Troy handguard. It's a machined aluminum piece with a matte black hard-coat anodized finish, cut to the mil-spec 1913 Picatinny pattern so your lights, lasers, grips, and other accessories drop right on. What sets this one apart from a plain rail add-on is the integrated QD sling swivel hole, giving you a slick spot to run a quick-detach swivel without bolting on a separate mount.
Unlike clamp-on rails that grab a factory Picatinny surface, this section secures with two screws into a backer on the inside of the rail. That direct-to-rail approach keeps it low and locked down, so accessories stay put under recoil and rough handling. Installation is straightforward and only takes a few minutes with the included hardware.
This is where it pays to know your setup. The section is designed for Troy's modular rail systems, including the TRX Extreme, TRX 308, Alpha, Delta, Troy HK rails, the T-22 Sport Chassis, and M7 uppers and M7 kits. If you're running one of those free-float handguards, the 4.2-inch length gives you a generous run of slots plus that swivel point in one piece. It's not meant for standard quad rails or generic handguards, so confirm you've got a compatible Troy rail before you order.
Troy Industries has a long track record making rugged parts for the AR platform, including OEM work for major manufacturers and government contracts. This little section carries that same made-in-the-USA reputation. It's a small, purpose-built upgrade that lets you customize a Troy rail to your exact accessory and sling layout instead of settling for whatever came stock.
It's built for Troy's modular rail systems, including the TRX Extreme, TRX 308, Alpha, Delta, Troy HK rails, the T-22 Sport Chassis, and M7 uppers and kits. It secures with two screws into a backer on the inside of the rail rather than clamping onto a factory Picatinny surface. Make sure you've got one of those compatible Troy handguards before ordering, since it won't work on standard quad rails.
No, the section itself has an integrated QD swivel hole but the swivel is sold separately. That built-in hole lets you run a push-button quick-detach swivel without adding a separate mount. It's a clean way to set up a forward sling point on your Troy rail.
Yes, it's machined from aluminum with a matte black hard-coat anodized finish. That keeps it lightweight while holding up to recoil and everyday handling. It follows the mil-spec 1913 Picatinny pattern so standard accessories mount right up.
Installation is quick and simple. The section bolts on with the two included screws and typically takes just a few minutes with basic tools. Once tightened down it sits low and stays locked in place under use.
