Minimum eye relief of the Hi-Lux scope is 8.7″ at 7X and is perfect for the K31. Most scout scopes are low power optics good for a quick shot at shorter ranges but not so good for target shooting at distance. With a variable power scope like the Hi-Lux I have the best of both worlds. I can turn it down to 2X and hammer targets off-hand at 50 yards or I can sit at the bench at 100 yards and test my handloads at 7X.
