I want to upgrade my AR15 with A1 sights to an A3 receiver. I would like to us my 20" H barrel with rifle feed ramps. But all the A3 receivers I see online seem to have M4 feed ramps. Is there any way to make my barrel ramps and M4 feed ramps work together? Online research seems to be negative. Does anybody know how to do that? I wound like to find a receivers with no feed ramps. Does any one know what brand sells A3 receivers with no feed ramps and where to purchase one. Thanks for your opinions & suggestions.
