  1. Raylee (verified owner)

    Exellent product and price. Only had one minor issue when building, the hole the mag ejection button slides through had a minor imperfection (mass produced lowers something is expected to be slightly off) a buffing session with a file fixed mostly. Exellent weapon, exellent build. 10/10 would buy again!

    Have built 3 of these. Solid build. The quad rail makes it extremely heavy. My next build will be will that keymod rail instead.
