By the way, it’s easy to take the carry handle off that barrel and put it on the other. Just take screw 23 out and the handle assembly will come off. Then push pin 5 out, 7 and 10 will then come out. Invert the barrel so pin 8 drops away from the barrel and 9/12 will slide off the barrel.
It takes 10 minutes to swap it from one barrel to another… Peter can probably do it in less than 2 minutes.
Did you use the gas regulator that was on the barrel? What setting did you use?
