I am thinking another 177 will be my next purchase and it will be a carbine. Possibly with a bottle. The AvengeX tactical carbine is interesting but I am not a big tactical fan and I question how well made the Air Venturi stock will be (and is the comb height adjustable?). But I also find the bottle just plain ugly. I would MUCH prefer a fill probe to that ugly foster fitting bottle. Is it just me?
