Jammed onto my buffer tube - Presma Skeletonized AR Mil Spec Buttstock

Looks nice but the stock jammed after 5 rounds. Tried to adjust to better fit my shoulder and the release lever will not budge. Scratched up my buffer tube pretty bad and I can't even take it off. I have a mil spec Spikes Tactical buffer tube assy and I bought a mil spec skeletonized stock. It is stuck in the 6th position and it looks like a part in the release lever mechanism is rotated. Ruined my Spike's Tactical buffer tube and can't even get it to adjust. That was awaste of $130 and now I also have to order another buffer tube. Total loss, about $180. Not good!
