Types of AR-15 Building Kits | Explained in Detail!

In short, unlike a full-fledged rifle, ar15 building kit is on the structural side of more things, with different levels of assembly to turn the weapon into a long-range trained firearm. These include adding the entire bottom to the top and adding and oiling the log, which is probably the easiest level to build an AR-15 from scratch. So of course everything is in the middle.

Types of AR Build Kits

Spare parts kits. One of the most common and often cheapest types of kits is designed to fill a receiver with the bottom exposed. They usually come with everything you need to loosen the trigger, holster, and bolt, except for the retaining pins. These simple kits are perfect for those who are ready to go to the top and want the experience of building the bottom with the necessary parts or upgrading anything about AR.

Partial Build Kits

Second, you'll find kits that include all of the above, as well as some furniture, usually superior protection, and sometimes inventory that includes both. These kits are perfect for those with a bare lower receiver and stand-up upper receiver who want to change the look and performance of an existing rifle or convert it to a fully functional firearm. These kits can often be great value for money.

Complete Building Kits

You will find that the more expensive kits have everything except the lower receiver. That is to say, they have a complete set of lower parts, some furniture, and a complete upper drawer, which includes a barrel, a bolt carrier group, a muzzle device, a handguard, and even some metal badges. Assembling the top will likely start your price up a bit, but you'll still save yourself the trouble of building the bottom.

Trigger Kits

Finally, some kits focus on the trigger, often involving just the trigger itself and the corresponding springs. These kits often include the best triggers available and are designed for people who have a fully functional rifle and want to upgrade the trigger. One of these kits is one of the best ways to get basic AR, which really freshens up the feeling of shooting it to your heart's content, as many don't like the mile-specific triggers that appear on most ARs these days.
