I am looking to buy a new rifle. Just wondering which one may be more fun to shoot, I will be shooting at indoor ranges at the moment. Just looking for some pros and cons on a 16 inch barrel or 10.3 inch barrel. My biggest concern would be with the MK 18 or 10.3 inch barrel what I still be able to hit a target at 2 to 300 yards? Any comments or advice would be greatly appreciated thank you and happy Canada Day.
