I bought a model L carbine 22-250. Barrel is good and accurate. Problem is after shot, bolt is extremely stiff, I'd guess im putting 30 pounds pressure on it to raise spoon handle So i find the bolt doesn't have the pin release by the handle shown in the manual. I wanted to take it apart, but can't do without the release pin. There is no missing pin. the handle is solid where the pin is shown in the manual. Any help would be greatly appreciated. I did put cleaner in firing pin hole to hopefully run through and think the bolt opens slightly better.
