Hi All, Recently I haven't been as focused on getting a new battery for this gun. She's a beauty, but I have decided that I want to pursue some other things. SO! check this out: Pics here: https://drive.google.com/open?id=1iuHBWyEG3USnILWV2a5Cx4uXocGwKEDx I upgraded the barrel assembly to Clandesetine Custom RHOP 6.02mm 509mm barrel, modify ryusoka flat bucking, hunterseeker MNUB and lonex hop chamber. I did all the work myself, I can promise you all parts are there or I'll give a full refund. I did not need to upgrade the spring, it chronos around 480fps with .2g BBs. My goal was originally to get it at or over 500fps. When I bought it, I took apart each magazine, cleaned them, lubed them with a dry silicone lube. All 3 mags now feed beautifully. I also replaced the charging handle spring, it's brand new straight from ARES. I also disabled the ambidextrous fire selector, still have the parts, I can put them back if desired. It's much smoother without them though. The whole system works great as it is, scope is perfect, it's illuminated and comes with good batteries. It's very accurate and consistent! I didn't get a battery for the RMR, so I keep the cover on it. Very deadly at 100ft, consistent enough to make kill shots well past 300ft if you can get the elevation and hop adjusted. The gears are stock, but it runs very well. I only took it apart once to visually inspect shims and lubrication. The gearbox is easy to disassemble, the extra electronics are just one extra step. TLDR: -RHOP Clandestine Custom 509 x 6.02mm Barrel -Modify 70D flat (nubless) bucking -MNub installed -Lonex Hop chamber -brand new OEM charging handle spring (pictured in drive) -Quick-change Spring gearbox -Upgraded FPS (480 currently) -new M170 spring included in packaging -3 midcap Magazines included, all cleaned and lubed recently -Illuminated scope (2.5-10x40) adjusted (currently 4x) and batteries included -45 degree offset RMR for close range targets -preset to semi-auto only -Ambidextrous fire-select currently disabled, option to re-enable available I'd like to ask for $550 with FREE SHIPPING for you.
