Sub $400 Budget AR15 Build List

Below we have a list of parts we carry for a basic, budget AR15 carbine build. The objective here is to get a functional rifle at a sub $400 starting price point. To that end, stuff like sights, sling loops, mags etc were left out of this list. Given the modular nature of the AR15 platform, most, if not all, of these parts can be upgraded. Maybe that will be a future article.

As we are not a FFL dealer, we’ll leave out the serialized lower from this list. You can get those on sale at almost any point in the year from your LGS or any major retailer. Just add one of those and put this no-frills rifle together in a couple hours.
