Wrong handgurad size

by

Build quality is good but the handguard is not 12". I measured 10.25". The grenade launcher notch is exposed which would have been covered if it was actually 12".

You get what you pay for

Barrel pin too small for slot in receiver. When they tightened it at the factory the barrel canted to the right. Bcg wont go into battery at all. Receiver and handguard finish is horribly mismatched. As usual Primary Arms was quick to ship.
