The Aero Precision Stripped Upper Receiver is the perfect compliment to any stripped or complete lower receiver. Forged from 7075-T6 aluminum, this receiver is built stronger than the majority of options built from weaker and cheaper 6061 aluminum alloys. This solid construction ensures that this stripped upper can last a lifetime of hard use once assembled. Precision machined to mil-spec M4/M16 specifications, this upper is fully compatible with all standard parts and lower receivers. It also features M4 feed ramps to ensure compatibility with all barrel extensions and maximize ease of feeding from any and all magazines.
The Aero Precision Stripped Upper Receivers sold by Bison Tactical are the version with NO forward assist slot. This helps to keep the upper’s overall weight down to only 6.5 ounces and additionally removes the weight of the forward assist assembly itself. This brings the total weight savings compared to a traditional upper receiver to approximately 3.5 ounces, or nearly 0.25 pounds!
