Caldwell's 7-Rest is a truly innovative shooting accessory that utilizes a unique design to deliver exceptional versatility and true value. The asymmetric frame provides great stability while maximizing length adjustability. By simply loosening the lock knob, the angle between the two halves of the frame can be adjusted to change the distance between the front and rear supports. Having the frame offset to the side of the gun also gives adequate clearance for extended magazines on semi autos (AR-15), lever actions and rolling blocks. Another benefit of the frame design is the ability to reverse it for right or left handed shooting comfort. Fully adjustable overmolded front and rear supports holds your gun securely while protecting the stock and forend. All these features rolled into one rest result in a rock solid, all in one shooting base with plenty of height and length adjustment to accommodate guns of virtually any length. Folds quickly for easy transport and storage.
