I was wanting to install an ambidextrous charging handle on my G2, but could not find one that fits this pattern gun. I found a Tac Latch by Badger Ordnance does the trick, Its not ambi but I'm left handed so the latch is easy to get a hold of, it adds about 5/8 inch to the charging handle width, easy to install, just drive out the roll pin an replace with the new latch. Plus it was only 19 bucks.
