Recently picked up the H&K 416D 22LR. Ran 100 rounds smoothly through it today and was very accurate with stock sight at 50 yards. It was a great deal of fun to shoot and I see shooting this a lot due to the "fun factor" and low cost of ammo. I wanted a rifle that I can share with friends when visiting that would be easy to handle and exciting to shoot. From H&K: The .22 caliber HK 416 is loaded with authentic features.
