It's made well and it does it's job. If you want a small drop, this is the way to go. It only moves the tank down about an inch. Comes in lots of colors......you can't really screw a drop up.
Weaknesses:
Not much that I can think of. Wondering if the nickel has the same chipping problems as the barrel though.
Conclusion:
Cory Wood seems to be slightly confused. Although he wrote a review for this product, he failed to realize that IT'S NOT A GUN.
Anyway, if you want a small drop this is something to check into.
