Upper receiver - Primary Weapons Systems MK111 MOD1-M .223 Wylde, 11.85in bbl Upper Receiver

Ive been searching and waiting to get one of these uppers for months.Finally checked on optics because they usually have a little of everything and they did.ordered it before it disappeared and before a price change happened because it was a couple hundred$ less and within 2 days i had it. Can always count on optics and there shipping and customer service is great.You talk to a real American person you can understand and they go above what they have to make sure you've satisfied!! I've put together a ciuple AR's now from parts from them without any promblems and always got good advice on how to make sure gun is running top notch!!
