Installed on my Ruger 10/22 Carbine rifle in about 20 minutes. Didn't receive instructions to install the bi-pod assembly so you really don't know which which way to mount the barrel clamp to ensure the the legs fold forward and not backwards. Helps to have level to ensure when you're tightening down the barrel mount your rifle is perpendicular. Overall, a good inexpensive bi-pod assembly.
Pros: Price & Application
Cons: No directions
