I bought an m4-22 upper gen 2 a few weeks ago.
About 650-700 rounds through it, getting ready for an Appleseed.
So far so good, and I can now use my AR at my (pistol) range.
4 mags from black dog.
Scoped, with sling.
Massachusetts.
Ammo:. Aguilla 500 shots, maybe 3 stovepipes, during breakin. Whole box was great. Worth it! Rem and winch had issues.
Paid 260 shipped.
