I am considering my first PCC and have mostly settled on the GMR15 after conducting research. I have played around with the configurator and am hoping those experienced with the platform have some feedback regarding some of the options I am unsure about.
Thermal dissipator: Based on my searches, there seems to be a roughly 60/40 no/yes split on this option. Obviously, the main downside is the additional 5 oz of weight added around the barrel to a gun that is already front heavy. Under what conditions would the increased cooling become noticeable? I am located in TX, so I would be shooting in hot temperatures for ~1/3 of the year.
Trigger: Roller trigger or flat trigger? I generally like flat triggers and have no experience with a roller trigger. I understand the potential benefit of the roller trigger, but I wonder whether the constant lateral movement along the trigger could be distracting, even if it doesn't cause shots to be pushed laterally. Anyone with the roller trigger regret it?
Trigger spring: Any reason not to go with the yellow 3 - 3.5 lb springs?
SCS: I'm looking at the short stroke SCS with the two tungsten and three steel weights, which is the mid weight option. I shoot factory ammo, generally 124 gr, though also some 147 gr.
