The AR-15 has been the go-to battle weapon for both the army and civilian use since its introduction in the 1950s. It was designed to be lightweight, run in harsh conditions, and be semi- or completely automatic. In the weapons business, this firearm is a tried and tested staple. If you’re going to make one, you’ll need the best AR-15 lower parts package.
What Is a Lower Parts Kit?
An AR-15 is made up of over a hundred different pieces. The majority of these components are located towards the bottom of the receiver and are actually the most significant. The trigger section, safety, hammer, handle, magazine catch, and buffer assembly are all part of this lower unit.

- Trigger Pin

- Safety Selector
- Disconnector & Spring

What Do You Look for While Purchasing an AR-15 Lower Parts Kit?
It’s a fascinating challenge to create an AR-15. Since it contains the most moving components, the AR-15 lower section package is the most complicated component of the rifle. But you can just have the right LPK for your AR-15 to make this job a lot simpler. And in order to do that, you must pay heed to the following:
Resistance to Corrosion
One of the AR-15 platform’s architecture ideals is that it should be able to withstand harsh conditions and ecosystems. It should be able to get wet without sustaining significant injury. This is especially relevant if you live in a humid environment. You must guarantee that all of the critical components in your AR-15 parts package are corrosion-resistant. If you want a lifetime of corrosion resistance, go for the best chrome lower parts package.
Components
You don’t need a complete parts package if you’re not starting from scratch and already have a stock and gun handle, for example. Anything like Geissele’s LPK would suffice. If you’re beginning from scratch with only an AR lower, though, a complete package is the way to go. Parts from various LPKs may be mixed and matched as long as they are compatible.
Manufacturing that is of high quality
Often choose the right AR-15 lower package with parts from trustworthy manufacturers. The lower is made up of a lot of small moving pieces, and if one of them breaks, your gun could not even shoot. To ensure a smooth and consistent process, some of the components must be accurately machined and coated. As a result, select vendors that announce that their materials are subjected to both magnetic particle and high-pressure inspection.
If you’re fixing a gun and already have the lower components but stuck, Adventure Survivalist can help you get the rest of the way to completing it.
