Look here under germany and see the Pentagon "F" mark..

The receivers are stamped to distinguish quickly a legal no license or full power license gun. The receiver is the power plant and most times not so easy to covert to full power then if you do and the guns receiver says not and you dont have the license ... Well not going to be a good day for you if your called to a check by law enforcement. Lol .
I’m at 5lbs at full power, under the 5.5 limit. Maybe there was something wrong with it. They replaced the piston, piston seal, compression tube and cocking arms. The good thing is that at the time they were only available in full power for .22 but mine came back with both power levels.

???... Dont know outside if the tube with a change in transfer port sizing then a spring .. even of full power you can go down with a spring but to go up to full youd need to change the diameter of the port + a spring.

But thats somthing i never had to worry about . Its just USA full power for me i guess.. maybe a UK forum has info on that conversation / how to.

Also maybe you got that 1 in a million gun with a bad transfer port and no one looked at that . Poorly drilled or somthing choking it like hard factory sluge ... Ive never run onto that so i can only guess.

Then like mycap said maybe a defective barrel in some way could do it .
