Up for sale is my PWS MK107 long stroke piston upper. The upper is in great condition, has about 600-700 rounds through it. I know how some people feel about rattle canned guns so I tried to take that into account when pricing. Please feel free to reach out with any questions.
Surefire muzzle device installed, factory CQB muzzle device included, along with the gas adjustment tool, and boxes.
$800

Trijicon MRO green dot and reptilia mount can be include for an additional $250.
