The Streamline and Dreamline are floating barrel guns. This clamp will reduce the risk of bending a barrel out in the field and may improve accuracy. Accuracy improvement is not guaranteed and use of the clamp is user choice. Please do your own research and check youtube for videos by users who have added clamps. The clamp can be used anywhere along the barrel.
This clamp will not damage your barrel or tank, no metal parts touch your gun.
Addition of any heavy accessories (such as a bi-pod) to the mount will add weight to the barrel and move your point of impact. If using a bi-pod position the clamp close to the stock to reduce the effect.
