Harris No. 5 AR-15 Round Handguard Adapter

The Harris No. 5 Adapter is the dedicated mounting solution for AR-15 and M16 rifles equipped with standard A2-style round handguards.

Benefits & Use Cases

The No. 5 adapter is perfect for shooters who want to maintain the classic "Service Rifle" profile while gaining the stability of a Harris bipod. It is specifically designed to sit flush against the handguard, ensuring that your bipod remains centered and secure even during rapid fire. This makes it an essential tool for target practice, coyote hunting, or tactical training where a supported prone position is required on a standard carbine or rifle-length setup.

Installation is straightforward and requires no specialized tools, making it a quick upgrade for any rifle with standard cooling vents. The internal backing plate spreads the load across the plastic handguard, preventing cracking or warping under the weight of the bipod. It is a lightweight, effective, and professional-grade accessory for anyone looking to maximize the precision of their AR-platform rifle.
