Rammer: Thats the exact gun that I want to build!! What lower do you have? I need to buy either Stag, Spikes, Vulcan, Superior, just because I am in California so I need an off-list lower and then bolt the mag in so its not detachable. Yeah it sucks but thats my only option. How does it shoot? Whats your range? I hoping to shoot around 250-300yrds with it, and then use my PSS for anything longer.
