I need to see your SIG 556 or .308 AR (AR-10 or DPMS)

[Exile Machine]

I need to see your SIG 556 or .308 AR (AR-10 or .308 DPMS) rifle. I want to take off the pistol grip and make some measurements, maybe take an impression with some PVC clay. PM me if you have one or more. Only need to see it for a few minutes. I'm investigating making some modifications to my company's Hammerhead grip to fit these rifles and I want to see what will be involved in making it fit.

Thanks,
