I had been looking to buy an on/off bottom line for some time and the evil was availible at my local pro shop so i decided it pick it up.
First impression were good. it looks very nice and has a rail and all monting hardware included with it, i know sometimes with other products you need to buy a rail seperate when you buy a new asa since others don't fit and/or it didn't include one.
it looks very nice when mounted on my marker and when i screwed in a 48 tank and a 20 ounce tank in it, the balance was nice and i could shoulder the tank to my playing style perfectly.
a little on the heavy side. but for a good looks and design this asa is a must have.
If i could i'd give this a 9.9 only because it cost me 50 bucks but others might find it cheaper other places.
