Aim sports gas block jig - AIM Sports Inc AR15 Gas Block/Tube Roll Pin Jig

For as many gas blocks as I put together I figured it would be great if they made a jig for it and low and behold I found this little piece of junk. First off NONE of my dozens of gas blocks would fit in there. Don't know what gas block this was designed for but apparently its for something smaller than a low profile has block. Absolute waste of money. DO NOT WASTE YOUR MONEY! Don't know if there's a better alternative out there but this definitely isn't the answer. Just wasted my money shipping it here then shipping it back for a refund. OP however made the returns process easy peasy.
