We-Tech MK17 Gas Blowback - $275 shipped OBO We-Tech SCAR-H GBBR pretty much all stock. Only a few enhancements, nothing big. I am the second owner, however, I did maintenance it, and fix a majority of the minor problems were present. The gun will come with 2 (non-leaky) magazines. The only enhancement I have done to this gun is the receiver screw replacement (besides the maintenance stuff). On all GBBR SCARs, the user is recommended to replace the 6 receiver screws to prevent the slamming of the bolt from pushing all the barrel assembly internals forward. With the replaced screws, none of the barrel assembly parts are pushed forward when the gun is fired. The bolt catch does work. -Magpul K-Grip (FDE) The bads: -Most (if not all) steel parts of the gun have minor rust on it. Not really a big issue though as all the steel parts on the gun are cosmetic parts. -Previous owner applied JB-Weld to the selector switch, I did get most of it off so the selector moves like it should. You can try to clean it out more to reveal the screw holding the selector, just replace the selector. -Sometimes, the gun has a hard time feeding the last round of the magazine. Tested with both magazines, both had the same issue. I believe its a worn nozzle. -Lot of scratches and cometic wear from the previous owner. Besides that, there's nothing else wrong with it. *Since it is located in Honolulu, Hawaii, the upper and lower receivers will be split and placed in the same box. I will make sure everything is secured and padded properly to prevent damage to the product. More photos upon request.
