Each of these rubber ladder guards from firearm accessory experts Dagger Defense protects your beloved tactical firearm, your gear and yourself, while affording better weapon control and comfort - all from one compact, affordable accessory! The durable rubber rungs fill the gaps in your tactical rail, preventing the accumulation of dirt, moisture and grime in these small, hard to clean spaces. They also eliminate sharp rail edges that can injure the rifle's operator and damage unmounted rail areas and other sensitive gear like ropes - easily abraded or severed by uncovered rail edges. The guards’ rubbery, ergonomic design improves grip, thus boosting control and accuracy. Each 6 3/4" long x 1 3/8" wide black ladder guard in this handy 4-pack covers up to 18 rail slots and is fully adjustable by trimming to your desired length. And since it's from veteran owned and operated Dagger Defense, you can rest assured it's built to endure even the toughest field conditions.
