Hi I'm selling my Primary Weapon Systems Long Stroke (ak style) piston upper. These are known to be rock solid reliable, clean running, and accurate. 300 blackout and less than 100 rounds through it. I just don't use it is why I'm selling. 

it's a MK109 MOD 2-M

These retail for $1,300 and up. 
This will need an AR "pistol" lower or you have to sbr it. 

Questions welcome.
