I think the piston is meant to stick in the chamber for a second when the bolt is retracted and then spring back, correct? Well mine does this only sometimes. Other times, the piston is stuck inside the bolt and moves with it. Also when the bolt locks back, the piston will frequently be sticking an inch or so forward out of the bolt. Is this a common issue? The hop up is off, I changed the oring on the piston for a HBF P014, then changed it back again to the stock one and the problem is still happening. I have been using this, http://www.homedepot...51#.URpaFqVX0s4 and the piston is well lubed.
If I need to take some pictures I will later. Any help would be appreciated.
What I believe is meant to happen
And what actually happens
