AR15 Build Kits

AR15 build kits are one of the most satisfying ways to put together a rifle — you know exactly what’s going into it, how it fits together, and why every part was chosen. Whether it’s your first build or another addition to the rack, starting with matched, quality components makes the whole process cleaner and more reliable from barrel to stock.

The kits in stock right now cover a wide range of configurations — complete with matched upper and lower receivers, bolt carrier groups, and trigger assemblies ready to go together. Brands like Aero Precision, Anderson Manufacturing, Palmetto State Armory, Ballistic Advantage, and Bear Creek Arsenal represent the kind of trusted names that belong in a serious build. Inventory is verified in real time, so what’s listed here is genuinely.

Non-serialized components — furniture sets, parts kits, BCGs, and accessories — ship direct to your door with flat-rate shipping and no hidden fees. If your kit includes a serialized lower receiver, the built-in FFL locator makes it easy to find a licensed dealer near you by ZIP code to handle the transfer.

Pick your configuration, add to cart, and we’ll have it out the door fast. Arms East also ships to Canada for licensed PAL holders.
