They come up with some interesting ideas on this rifle. It has a vertical safety, quick change barrel and bolt head (for easy caliber change), semi-control feed action, a very unique take on the plunger ejector, lockable magazine that can be top loaded, and adjustable trigger. The "Trail" version seems like it could be a great truck gun/ varmint calling rifle.
I hope these turn out to be good rifles. On the down side, it looks like the 527 is discontinued.
