Mr Johns,
Not many responses from Regal owners, so I'll chip in. First, using the search tools of this forum you can find a huge amount of (nearly 100% positive) information about the Regal that's been posted since the forum started. Also 'Sir' Ted of hold over fame has an excellent video review of the gun on youtube.
I've had a Regal for about 3 years now and love it. About the gun: its by far the most affordable entry into Daystate's line. There are less expensive options, such as the AA S-510 FAC that probably shoot as well. So why buy a Daystate? As I and many others have posted earlier, its mostly about quality and the pleasure of owning a gun of this class. The gun will last a lifetime; the walnut stock is stunning, beautiful checkering, curves in all the right places; the 10-shot magazine is a joy to load and use, there is nothing comparable from other manufacturers (not surprising if you ever have the unfortunate desire to purchase another magazine, its another $100); bottom line, this is a beautiful gun with a long history of satisfied owners. Accuracy is lethal for small game (you will be surprised what you can take down with well placed shots). Add a Huggett moderator and the gun is nearly silent. The 30 ft lb option is probably best for .22, and will give a highly reproducible 30 shot string, even though the gun is not regulated; this is due to the Harper sling shot, which does an excellent job. The gun was sold (and designed) as a hunting rifle, where its more than accurate enough for doing its job, over and over again. For target shooting, there may be better choices? Although a 40 ft lb version is available in .22, your accuracy will likely decrease. A .25 is also available, but these are unusual, and not much information has been posted.
