Nice group of rifles. I have had the pleasure of playing with most of the guns shown, with the exception of the Japanese Arasaka carbine.
There were many that came and went, but the 03A3 and K31 is my pick and I still play with them.
I cast my own bullets and shoot reduced loads, in them. They are more fun to shoot, this way than with full house loads.
Accuracy is way better than most would expect to to be.
K31 seems to be the best, and will hold around an inch at 100. The 03A3 is about as good, but I seem to get along with the K31 sights better than the 03A3 sights.
Still learning, and improving my loads, and bullet quality.
