Thanks for posting this. The Brocock Ranger XR looks interesting. I already have the Umarex Gauntlet 2 in .22, but I think I'm going to sell it and find a replacement. It's got a lot of great features for the price, but it's too large for lugging around on a hunt, and the length of pull is too long for my kids to decently shoot. I'm digging the AR style stock on that Ranger XR. Something like that could do the trick.
The Air Venturi Century looks very interesting to me. However, the reviews of one of the others by the same manufacturer make me wonder about reliability.
