Iíve got a Hyperframe on my 68 Automag. Stock bolt and valve. The first 15000 shots, no problem at all. Then the sear stopped holding the bolt and it started venting CO2 into the barrel. I had to push the bolt back in with a pen to stop the venting. Iíve checked the lip on the bolt where the sear catches it and itís only got a bit of ware. The sear doesnít look to bad ether but is a bit worn.
Iíve been told that it might need setting up. How? The manual said that all I need to do is slap it on. The only thing that can be adjusted is the solenoid.
Someone please help me!!
