Specifications

Type	A Complete Upper Receiver
Price	$1,199.99

The short version

A complete upper takes the guesswork out of a build. Headspace, gas system length and barrel extension are set at the factory rather than on your bench, which removes the failure modes that cause most home build problems.

What to check before ordering

Confirm the receiver size matches your lower, AR-15 and AR-10 pattern are not interchangeable. Check gas system length against barrel length, and confirm the muzzle thread pitch matches any suppressor or brake you already own.

Price and what it buys

At $1,199.99 this is a premium option. You are generally paying for materials, machining tolerance and mounting systems rather than a dramatic difference in sound.

Before you order

This ships directly to you. See our shipping and delivery page for processing times, carriers and any restrictions that apply to your address.

Looking after it

About this finish

A plain black finish is the most durable and the easiest to touch up, and it hides oil and carbon rather than showing it.

Handling marks are the honest measure of use. Some owners prefer a finish that records it, others one that hides it.

Build notes

Record your torque figures somewhere. Six months later you will not remember what you set them to.

Practical notes

Check receiver pattern before anything else. AR-15 and AR-10 pattern parts are not interchangeable, and AR-10 pattern is not standardised between makers.

Gas system length has to match barrel length. Get that wrong and you get a rifle that short strokes or one that beats itself to pieces.

Also consider

Headspace is set at the factory on a complete upper, which removes the single most consequential mistake available to a home builder.

Muzzle thread pitch decides what you can fit. Confirm it matches any suppressor or brake you already own.

Experience talking

Gas system length has to match barrel length. Get that wrong and you get a rifle that short strokes or one that beats itself to pieces.

Barrel contour affects heat and balance. A pencil profile is a joy to carry and heats fast; a bull barrel is the reverse.

Muzzle thread pitch decides what you can fit. Confirm it matches any suppressor or brake you already own.

Frequently asked questions

Is this in stock at this price?

Yes, $1,199.99 is the current price and this is held stock. Prices move with supply, so the listing is the authority rather than a cached search result.

What thread pitch do I need?

That depends on your host firearm rather than on this item alone. If you tell us the rifle, we can confirm compatibility before you commit.

Where do you ship from?

Orders ship from the United States, and delivery is limited to lawful destinations within it.

Will this fit my action?

Check the inlet or interface specification against your action before ordering, and ask us if you are unsure.

Do I need threadlocker?

Blue grade on non structural fasteners is sensible. Avoid permanent grades on anything you may need to remove.

What torque should I use?

Follow the manufacturer’s figure with a torque wrench. Guessing by feel is the most common cause of accuracy loss on a rebuild.

Is there a warranty?

Manufacturer warranty applies. Terms vary by brand, so check the maker’s policy for the specific item.

Do you ship this to my state?

In most cases yes. Some states restrict specific configurations or components, so check the shipping page or ask before ordering.

Is this genuine manufacturer stock?

Yes. We stock genuine product from the manufacturer or their authorised distribution, not grey imports.
