I haven't seen a ton of reviews so far, there was one on GA Digest back at the beginning of September and the reported accuracy was nothing to really write home about. To be fair the author didn't have any match grade .22LR available, just a varied mix of plinking ammo, so you should take the accuracy testing with a grain of salt. The only other review that I saw was from the one above and what I saw there didn't inspire much confidence either, especially for using Lapua ammo.
On paper this rifle sounds great but if I was looking for a new rimfire for precision use to take to some matches and use as a trainer, what I've seen so far would only push me to other rifles. As a lightweight .22 for carrying around the woods to wack squirrels and shit, it seems like it'd be an great, although pricey option.
