Not a common problem. Give it a good thorough cleaning, and check 1) the proper orientation and condition of the piston and piston seal 2) the condition of the O ring 3) that the gas ports are free and open (a small drill bit spun between your fingers works) 4) that the action spring tube in the buttstock is clean and everything is slick and lightly lubed 5) that the link is not bent or broken 6) that the chamber is good and clean.
