What is an AR-15 Kit?

Before we dive into the list of top-rated kits under $300 let's first understand what constitutes as an "AR" kit. An AR (Armalite Rifle) is a semi-automatic rifle designed by Eugene Stoner in the 1950s and later adopted by the US military as their primary infantry weapon, commonly known as M16.

An "AR kit" typically includes all parts required to assemble a semi-automatic version of this firearm at home; it does not include serialized components like lower receiver or barrel which need FFL transfer from licensed dealers.

Benefits of Building Your Own Rifles with Kits

Building guns from scratch has become very popular among gun enthusiasts over the years due to several benefits such as:


Choosing your own parts provides more customization freedom than when buying pre-assembled rifles off-the-shelf while also saving time on assembly since most parts come pre-fitted.


Building your own rifles allows you to save money while also acquiring knowledge about how each part operates within its system giving room for upgrades and repairs when needed without having professional help every time hence saving more bucks!

Learning Experience

When assembling firearms yourself using kits, it enables gaining hands-on experience with weapons that can increase knowledge about their workings which could come in handy during emergencies where professional assistance may not be available immediately

Technical Understanding

Assembly requires learning technical skills & concepts related directly or indirectly towards firearms operations making one better equipped to handle them in an emergency situation
