    I ordered four Aero Precision upper receivers and matching 15” handguards at an excellent price and even better customer service that included great packaging. Thanks for the extra fast shipping. Everything arrived in perfect condition despite the rough handling by the Gorillas that work at UPS, although, they are not as bad as the US Postal Gorillas; no one is. Would not hesitate to order again from B. King’s for my future AR needs. Semper Fi, brother.
