TruSight Airsoft has also designed a companion hop-up spacer that replaces the stock rubber cylinder in a typical hop-up unit. Although this spacer is not required, the hop-up effect of the Tru-Hop^TM bucking will be maximized with full area contact. Like the bucking itself, this spacer was designed in-house and fine tuned through experimentation. The end result is a product that stands out as an individual contributor to performance.

Compatibility (Gen3 & Gen2)

Some inner barrel requirements must be met due to the shape of the internal contact patch of the Tru-Hop^TM bucking. We designed the bucking with broad compatibility in mind. However, not all barrels will be compatible. Please ensure that your barrel window meets the minimum dimensions shown below. Ideally the corners of the barrel window should be squared, although we’ve had success with some rounded corner barrels.

Tru-Hop^TM is compatible with Automatic Electric Gun (AEG), High Pressure Air (HPA), and Gas Blow Back (GBB) airsoft replicas using AEG inner barrels. We recommend coating the portion of your your barrel shown above, and the exterior of your Tru-Hop bucking, with a thin film of silicone oil to aid in installation. Tru-Hop^TM buckings have a 500 – 1000 round break-in period before maximum performance is achieved.
