I just picked one up for 10 bucks shipped brand new on ebay. It's from an airsoft store. It's a 4x20 and is 10.5 inches in length. It looks exactly like the resin one I have except the scope bracket rings are off by a bit (single not double). Like I said, for this EE-3 I'm not going for spot on, I'm going for better than it was while trying to get as close as I can for as little loot as I can. Most wouldn't notice...:cheers
