For sale today is a Krytac LMG Limted edition. For those of you who dont know, this was the original style they came out with when they released the LMG. It was a limited run and they don't make them this way anymore. As far as upgrades, the list is as follows: - BTC Chimera mk2 - Siegetek gears (unsure of ratio, but I believe they're around 10:1) - aluminum air nozzle - Prowin hopup chamber - Prommy 6.03 tight bore barrel - G&G green bucking - wired to Deans (That's all that I know of, there may be more) I've also modified the box mag to ensure that BBs don't get stuck in a bad place, jamming up the mag. It feeds perfectly fine now. To build this gun at retail you would be paying over 800 dollars. I'm letting this go for under 400 as I need to slim down my collection and this takes up the most room. Price includes shipping. CASH/PAYPAL ONLY
