I've used both systems, the r93 quite alot and the r8 a small ammount.
It is a very intuitive system and I have found them nice to shoot.
The only things I don't like about them is the stock, quality wise it's just a synthetic stock and dosent live up to the quality of the rest of the rifle. Also mounting some scopes can be slightly troublesome.
If I was to buy one I'd order a Christianson arms carbon R93 stock and use Abe's recievers and aftermarket barrels, and just buy the bolt, mags and mounts from Blaser, I think you would end up with a very nice package doing this.
