Adjustable stock for a firearm
First Claim
1. An adjustable stock and cheek rest assembly for a firearm comprising:
- a support member connected to the firearm and provided with lock receiving structure thereon;
a stock slidably mounted on the support member;
a cheek rest disposed in overlying relationship to the stock;
a cheek rest adjustment arrangement connected between the stock and the cheek rest, and for selectively adjusting a position of the cheek rest in a substantially vertical direction relative to the stock; and
a movable member provided with locking structure and mounted on the stock for selective engagement with the lock receiving structure for locking the stock and the cheek rest in various axial adjustment positions along the support member,wherein the cheek rest adjustment arrangement includesa cheek base attached to the cheek rest,a lift base fixed to the stock,an expandable and collapsible scissors linkage connected between the cheek base and the lift base, anda rotatable adjustment device coupled to the expandable and collapsible linkage and formed with a cheek wheel attached to a lift rod having a threaded portion,wherein the lift base includes a forward end, a rearward end and a pair of spaced apart vertical sidewalls being formed with a first pair of aligned holes towards the forward end thereof, a second pair of aligned holes towards the rearward end thereof, and a pair of aligned slots located rearwardly of the second air of aligned holes,wherein the scissors linkage includes a pair of outer lift links coupled to an inner lift link, the outer and inner lift links having respective forward ends and rearward ends pivotally connected directly to the cheek base and the lift base by a pin arrangement,wherein the pin arrangement includes a lift pin which extends through the aligned slots formed in the rearward end of the lift base, and through aligned holes formed in the rearward ends of the outer lift links, the lift pin being configured to be movable within the aligned slots in the lift base during adjustment of the position of the cheek rest, the lift pin being formed transversely therethrough with a threaded hole which directly receives the threaded portion of the lift rod, andwherein rotation of the cheek wheel and the lift rod causes movement of the lift pin within the aligned slots formed in the rearward end of the lift base resulting in the rearward ends of the outer lift links pivoting about the lift pin and subsequent movement of the scissors linkage and the cheek rest relative to the stock.

Abstract
An adjustable stock and cheek rest assembly for a firearm includes a buffer tube extending rearwardly from the firearm at an angle relative to the firearm receiver. A stock is slidably mounted on the buffer tube, and a cheek rest is disposed in overlying relationship to the stock. A cheek rest adjustment arrangement is connected between the stock and the cheek rest, and is provided with a movable linkage for enabling vertical movement of the cheek rest relative to the stock as the stock moves along the angled buffer tube. A movable member provided with locking structure is mounted on the stock for selective engagement with lock receiving structure on the buffer tube for locking the stock in various axial adjustment positions along the buffer tube.
