To be fair, this came with a scope that I purchased from optics planet, so it was technically "free."
I installed it, the screws stripped, and even with new screws it was wobbly. Very cheap build. I ended up throwing it away and buying a different mount from Leapers UTG.
Pros: inexpensive
Cons: cheaply made, screws strip, wiggles even with locktite
