Sorry, I must have missed this when it was first posted.

Edgun Matadors are fantastic rifles - you'll certainly notice a difference to your R10 and HW100. Obviously, the handling characteristics will be different and, I found it to be less refined than an HW100 but, that's not a bad thing.
They feel very solid and well made - the one that I had was easily as accurate as my HW100.

For a bullpup they do give a good shot count as the air cylinder is quite large, running almost the full length of the rifle.

I found it easy to track on aim when hunting during the day and, also easy to use with a NS Viper as night.

If I had to give one criticism, it would be the loading bolt right at the back of the action - this makes it near impossible to stay on aim while you reload.
I'd like to see a side lever or semi bullpup version.
