So I shot my pcc without glasses for the first time today and got gas in my eye, more then I think it should be. I'm still playing around with buffers and so on, but now I want to start with deciding how long my barrel should be. It's 16 inch now and I can cut it as mush as I want. But it could be good with 16 with a "pinned" comp, if there isn't any benefit on going shorter.
But what is the "perfect" length with a comp? I use the gun for IPSC and Steel challenge.
It's a QC10 receiver, barrel and bolt(without the extra weight in it) and a JP Enhanced silent capture (2 tungsten, 3 steel). So either it's more buffer weight/more spring pressure or a shorter barrel to start with. Looking on super slow mo it seems to recoil hard with 124gr ammo (160pf).
I like to have my hand stretched so a 12 inch handguard is probably the shortest I will accept.
Thanks!
