A Picatinny style Scope Rail for the Nelson Custom Guns 1911 22lr conversion unit.
Agree with the prior reviewer - this is a super easy solution for adding a red dot optic. Didn't even need to remove the kit from the pistol frame. I am very pleased with it.
Two screws and you are able to switch between iron sights or a red-dot/scope. Rail is steel so the weight is still present.
