Does anyone know why Stag does not use M4 Feed Ramps? Does Rock River? Is this a difficult modification? How poor is the accuracy without the M4 Feed Ramps?
Opinion Needed: Which Upper Is A Better Buy - Stag 1/11 SPC II Chrome Lined or Rock River 1/10 SPC II No Chrome Lining. (Keep in mind Rock River is claiming 12 Months + lead time)
