AR-15 Do’s and Don’ts

Youtube is an incredibly valuable source of information if you can weed through the chaff to find the people worth following.

One of my prefered Youtubers is Highjak86. He has been working on a multi-part series called AR-15 Do’s and Don’ts. It is by far one of the better video series I have seen on the topic. If you are new to AR-15’s or you just want to get a better idea of what to put on your gun this series is a great place to start.

In his first video Highjak86 highlights gear placement. This is a great place to start as I see so many guns that are not set up for success.

For the first part this is the initial build list. As the video progresses over the 2 years he has been producing this series.

This video is just over a year later. As you can see the items on the rifle have changed drastically.  In this video gear placement is discussed again. Rifle weight is discussed in regards to the pros and cons of weight over gear.  Initial discussions are begun related to lights on AR-15’s.
