Unused Strike Industries Megafin XL Rail 12", $50, a little beefy but super sturdy, has a flip up front sight built into it or you could cover that with your own sight. These are no longer made. I can include a Ruger flip up sight set for $30 extra. Meet at the Academy on 1604/Potranco. Please no "call/text me" or "is it available" messages. Thanks
