Here we have my TWS M4 Key Mod Dinosaur with added after market scope which is included. The after market scope has a green or red light depending on your preference! Model number is KA-AG-200-BK. Comes with original ASGC receipts as well. I can't find the receipt for the scope which I purchased from Guncity. Will try to find this today. This is absolutely brand new in condition as I used this only once. I am only selling it because I'm quite a small lady and I found this to be too heavy for me. I wanted to use this indoors so ASGC altered the spring for me, to shoot FPS accordingly. You can always revert it back if you like. I also added the lens protection as well. Here are some of the technical details & the actual product link is here. http://www.kingarms.com/product_detail.php?id=2520# Suggested Energy Source 9.6V battery Maximum Battery Storage 11.1V Max.
