I finally got to the range last week and got a few shots in with these sporters using some GP11
I only had a 10 round box of GP11. After using a round in the K31at 50 yards to ensure that the front sight was centered, I shot 5 rounds @ 100 yards on a 5.5" reactive target. After the second shot @ 100 yards, the handguard flew off and I ended up shooting 3 more in a vain attempt to get a decent group. The first two rounds at 100 weren't bad--they were centered and a litle less than an inch apart. The next three after the handguard came off went a bit wild, but were still on the 5.5" target.
The 96/11 did considerably better. After shooting 1 round at 50 yards with it, It then put the last three into a clover leaf. This was the 96/11 @ 100 yards (8" reactive target):
After I was done shooting, I took a look in the barrel channel of the K31:
The barrel is far from "free floated", being fairly hard over against the right side of the barrel channel at the end.
I think these both have good potential. I'm thinking seriously about drilling and tapping the 96/11 to see how it does at longer ranges. I'm wondering if this would have any potential as a long range target rifle with the proper sights.
