Beware this stock. I got one for my Rossi. As most ATI products go, the mfg tolerances were WAY off. The forend stud didnt line up. It is excessivly heavy. The pistol grip is way too small, when compared to a standard AR grip. Plastic isn't really what i'd call cheap though. It feels really durable.
I've had 3 ATI stocks. None of them would fit w/o severe modification which I always felt was bad advertising, As they used to claim "drop in fit". I don't know if they still do or not.
Now what I wouldn't mind buying just the collapisble stock portion of it off somebody who has one. Though I would throw away the pistol grip and cheekpiece to put on an ar15 pistol grip and CAA or VLTOR cheekpiece for my truck gun project...
