I'm pretty pleased with the SGM tri rail that I got from Carolina shooters supply. i'm not using any lights or optics on it. The texture on the grip makes it nice when picking up the gun. I never really liked the factory smooth forend. The 3 rails really don't stick out more than the rest of the grip, so when moving your hand down the grip you don't hook fingers on the rails, like my Tapco on my Saiga 12. Just my 2 cents.
