Strike Industries AR Cable Management Rail Cover - Short, 2pc/set, Black, One Size, SI-AR-CM-COVER-S-BK

Instead of tucking wire anywhere you can and using cable ties or tape to hold it down the SI CMS will offer you a place to route and/or contain loose wire inside the cover cavity. Cables can be routed alongside the handguard across to the other side 90-degrees or U-shape.
