I recently purchased a Romanian MK99 from Wise Lite arms. I took it out the other day and had a very unpleasant experience. The first round I shot the case got stuck in the chamber. I had to take the gun apart to get it out. the case had a giant buldge at the base and the primer had a weak indent. Next shot... Click... No boom. Being a dumbass I tried again until I finally got a shot off. This time it extracted the spent case, but the case was bulged out again. Anyways I took some pics to see what you guys think. I emailed the company a couple days ago, but being a holiday weekend Ill have to wait to hear from them until tomorrow... Hopefully. Honestly I'm pretty f****** pissed about almost blowing off my face.
Yes the gun was properly cleaned and lubed. The gun was built from a kit so there was no cosmoline. It looked like they had test fired it even. When I took the gas tube off the piston had carbon on it. I even took the firing pin out and cleaned the inside of the bolt and extractor. I talked wise lite and they told me to send it back for repair/exchange. To be honest I kinda scared to shoot another gun they made but we will see.
