I have no idea though I want to paint the gun with a expensive paint job so I don't want to get some random cheap Chinese rail to get painted.
are there any higher quality options?
Hey have any of you guys heard of an app called Gunstruction?
its basically a 3D gun constructer where you can build up guns and see what they will look like before you purchase anything and it's Free!
(it's what I have been using to decide on how I want my tm to look like)
