I did find that the gun's plastic exoskeleton is a trifle too slick for the adhesive to stay put, but some black duct tape fixes that. Plus, the flashlight also comes with a swap-out conventional on/off switch, so you can just turn it on and not be bothered. Crosman's innovative Mohawk front sight is an inclined plane wound spirally around a cylinder. "Why didn't I think of that?" Many users, however, will opt for fast-shooting red dot sights. The dot sight has the usual windage and elevation adjustments plus a rheostat to control brightness. It also controls the size of the dot. Make it as small as you can comfortably see for best results. I used it outdoors at noon on a bright day without any difficulty. This Is An Earth-Shaker! As I said earlier, semi-auto pellet guns are not common. The few that exist start at more than $450 and quickly rise above $1,100. All are target guns rather than utility sporters. Crosman has broken down the cost barrier with a practical gun that sells for a little over $100! The basic rifle lists for $109 at Pyramyd Air, and the full kit gun sells for $200. Five Crosman Premier pellets sailed through that .272" group at 18 yards in a stiff wind! Shot with a dot sight and Gaylord's alibi eyes, this is excellent performance, especially semi-auto. I've tested both the basic rifle and the fully loaded model, and I have to say I like the bells and whistles better. As long as you're going to enjoy shooting, it doesn't cost much more to go first class. Thanks to Pyramyd Air for supplying the basic Nightstalker carbine and to Crosman Corporation for supplying the Nightstalker kit, speedloader and all supplies for this test.
