Frequently Asked Questions

Does this complete upper include a bolt carrier group and charging handle?
No. Like most Aero Precision complete uppers, it ships without a bolt carrier group and charging handle, so you can choose the BCG and charging handle that suit your build.

Will it fit my lower receiver?
Yes, it is built to mil-spec dimensions and fits standard AR-15 lowers, including Aero Precision M4E1 lowers.

What bolt and magazines do I need?
Use standard AR-15 5.56/.223 magazines and a standard 5.56 bolt carrier group.

What does “No Forward Assist” mean?
The receiver omits the forward assist plunger for a lighter, cleaner profile. Rifle function is otherwise unchanged.

Does it ship to my state?
Some states and localities restrict certain firearm parts. It is the buyer’s responsibility to confirm the item is legal where they live before ordering.
