I had my FFL dealer place and order for 2 Stag arms stripped lowers from AIM on Monday August 21st around 2 pm. My dealers clerk said AIM wouldn't give him a shipping price on the lowers. How much can I expect to pay for s&H on two lowers? I am located in central Florida. Just concerned as this is my first build and the clerk said the person on the phone gave him a hard time.
