Adjustable firearm butt assembly

An adjustable firearm butt assembly, comprising:

• a base plate selectively attached to a buttstock of a firearm, the base plate having a base slot;
• an adjustment nut aligned with, and transversely movable relative to, the base slot;
• a pad plate selectively attached to the base plate with the base plate being interposed longitudinally between the pad plate and the adjustment nut, the pad plate having a plate slot and a guide track, the plate slot being aligned with both the adjustment nut and the base slot;
• a guide pin having a portion selectively received in the guide track;
• and
• an attachment fastener selectively extending through the plate slot and into engagement with the adjustment nut to selectively attach the pad plate to the base plate, the attachment fastener being laterally movable with respect to the plate slot, and the attachment fastener being selectively movable between unclamped and clamped conditions via engagement with the adjustment nut;
• wherein the pad plate is selectively movable relative to the base plate and the guide pin when the attachment fastener is in the unclamped condition, the guide pin sliding along the guide track responsive to movement of the pad plate relative to the base plate and the guide pin;
• and
• wherein the pad plate is substantially prevented from moving relative to the base plate when the attachment fastener is in the clamped condition, contact between the guide pin and a track wall of the guide track at least partially restricting the movement of the pad plate relative to the base plate when the attachment fastener is in the clamped condition.
