To ready the Daystate Mk4 iS Target for shooting, remove the cap at the end of the air reservoir and fill the reservoir to 230 BAR with a SCUBA tank or high-pressure pump. Next, load the rifle.
Because this is a target rifle, I didn’t mess with the 10-shot rotary magazine, since my preference would be to load single shots if I were shooting field target with this rifle. Initially I tried loading the Daystate Mk4 iS Target without the benefit of the single-shot tray, but I found this to be enormously fussy and difficult. Fortunately, single shot tray is included with the Daystate Mk4 iS Target. It drops readily into place, is held there by magnets, and makes loading single shots absolutely straightforward. You rotate the bolt up and pull full back, place a pellet headfirst on the tray, and slide the bolt back to its original position.
It’s at this point that I encountered some of the weirdness that is associated with an electronically controlled rifle. The bolt, it turns out, doesn’t cock anything, so it operates super smoothly and very easily. The electronics do all the cocking of the action within the receiver. As a result, it is possible to trigger shot after shot, without moving the bolt, simply by pulling the trigger if the safety is set on FIRE. Now obviously, if you are not moving the bolt and loading any pellets, you will not be sending pellets downrange with those repeated trigger pulls, but you will be sending compressed air down the barrel, compressed air that could cause damage if in too close proximity to another object. (A fellow on one of the forums, using a different precharged pneumatic rifle, put his finger over the muzzle and pulled the trigger to see if there was any air left in the reservoir. The resulting pellet-less discharged wreaked havoc with his finger, and his next stop was the emergency room.)
When the electronics are turned off, the trigger has a small amount of play and feels as inert as if it were attached to a brick wall. Turn the electronics on, though, and it becomes a thing of wonder. There is a very light, but solid and unmistakable , first stage (which I found impossible to measure with the electronic trigger gauge), and at 7.3 ounces, the very crisp second stage trips, and the shot goes off
On high power, the Daystate Mk4 iS Target launches 10.34 grain JSB .177 pellets at 917 fps average for 19.4 foot-pounds of energy at the muzzle. On Power 2, it sends the same pellets downrange at 797 fps average for 14.7 foot-pounds of energy at the muzzle. Accuracy was excellent, as you can see from the target below shot at 32 yards, and the report, thanks to the very efficient valve and control system (which will deliver more than 100 shots per fill on Power 2), was to my ear no louder than an average high-power springer.
In addition, the electronic of the Daystate Mk4 iS Target offer a wide variety of control options for the shooter, including: magazine counter, shot counter, active display pressure, power, lighting, turning magazine counter on and off, single shot mode, and low pressure warning.
To be honest, I didn’t mess with any of these electronic settings. Instead, I contented myself with the pleasure of shooting an astonishingly accurate air rifle.
Til next time, aim true and shoot straight.
