I found it worked better with a Magpul flip-up iron sight than it did with the supplied carry handle. Perhaps the latter was defective as it wouldn't sight in till the windage was dialed all the way to the left. The flip-up didn't have that problem and soon came to rest not far off mechanical zero - elevation at the front sight post didn't seem to need adjusting.
So I advanced to contact against the paper adversary and its Green Bucket and Ice Tea Can allies. I won the firefight, fortunately, doubtless helped by the opposition's inability to shoot back. Ice Tea Can went down spectacularly, exploding into the air in several parts - huge fun.
As the sun began to set the 'value packs' ran out and it was back to the parsonage for meditative weapons cleaning and reflection on tomorrow's homily; water into wine. I'm all in favour of that, preferably in great, or 'industrial strength' quantities.
Self-verdict on latest gun? Worth every penny, for sheer enjoyment. Next stop - get sinister black Deathstar battle rifle in .308 - more stopping power you see.
Good shooting,
