The GrovTec US Inc GTSW191 is a 6-inch M1913 Picatinny rail built for AR platform rifles. This aluminum accessory rail mounts directly to your AR stock, giving you a low-profile, rock-solid platform for mounting optics, lights, lasers, or other tactical gear where you need it. Black anodized finish means it's durable, corrosion-resistant, and blends seamlessly with standard rifle furniture.
Picatinny rail real estate on an AR stock opens up a lot of practical possibilities. Whether you're running a carbine for home defense, a precision rifle for distance work, or a tactical setup for training, this rail lets you attach accessories without adding bulk or weight. The 15 slots give you flexibility in mounting position, so you can dial in exactly where you want your gear. GrovTec has been machining AR parts for years, and this rail reflects that focus on fit and function.
Installation is straightforward on any AR stock equipped with standard mounting provisions. Once mounted, the anodized aluminum construction handles the weight of modern accessories while staying true to specs—no flex, no wobble. It's the kind of part that disappears into your setup and just works, day in and day out.
| Length | 6 inches |
| Picatinny Slots | 15 |
| Material | Aluminum |
| Finish | Black Anodized |
| Compatibility | AR Platform Stocks |
| Model | GTSW191 |
The GTSW191 is designed for AR platform stocks with standard mounting provisions. Check your stock's manual or specifications to confirm it supports accessory rail mounting before ordering.
With 15 slots across 6 inches, you have plenty of flexibility. Most lights, lasers, or optics take 1 to 3 slots, so you can typically mount one primary accessory and leave room for others, or mix smaller accessories as your setup demands.
Yes. Anodized aluminum is a standard finish for AR parts and optics. It resists corrosion, scratches, and wear far better than bare aluminum, and it won't rust in typical field conditions.
