Abstract: An adjustable stock system for a firearm can include a buttstock slider configured to be slidably attached to the firearm for moving relative to the firearm between a collapsed position and at least one extended position. The buttstock slider can include a plurality of buttstock grooves defined therein. The system can include a lower stock assembly that is configured to mount to a firearm and a latch assembly disposed within the lower stock assembly. The latch assembly is configured to be moveable between a latched position where the buttstock slider cannot slide relative to the firearm and an unlatched position where the buttstock slider is free to slide relative to the firearm. The latch assembly can include at least one latch tooth configured to mate with the plurality of buttstock slider grooves when the latch assembly is in the latched position. The latch assembly is biased to the latched position.
