I seriously doubt that the barrel life will be what is claimed with a degree of accuracy needed to be competitive.

My hunting rifles all have the trigger set at 2#. A 3.5-4.5 # trigger for F-class is a poor situation. If mostly you are going to shoot run and gun type matches and only occasional F-class then OK, you know up front you are giving away points with a stiff trigger in F-class matches. I don't shoot run and gun stuff so I know little about the requirements.

I know nothing about the last two, but GA Precision has a big reputation that has not always delivered the agreed upon quality and because so many people have GAP guns a person is a fool to say in public that you don't always get what you pay for so you never read about the poor quality guns that were shipped. I saw a guy DNF over a broken firing pin first time out in what was obviously poor judgement on pin selection by GAP That said, I can truthfully say that there are horror stories for nearly every gunsmith I know. I do not know the current delivery status of any of them but I would not be surprised if it was double what they advertise.

5R barrels are good barrels with a proven track record for accuracy.

Knowing totally nothing about the quality of the other two guns I would prefer to go with GAP as George has a reputation for making things right if there is a problem.
