Saturday at the Movies: Do-It-Yourself AR-15 Rifle Assembly

Cheaper Than Dirt AR-15 AR AR15 building assembly video page

Cheaper Than Dirt (CTD), a Texas-based vendor of firearms, gun accessories, and ammo, has created a very complete web page on AR-15 assembly from start to finish. If you are thinking of building an AR, or upgrading your upper, trigger group, or buttstock, we recommend that you read CTD’s DIY ARs — Building Your Own AR-15 page. This illustrates all the components you will need for a complete AR build.

In addition, the page has a series of videos showing how to assemble each element of the AR-15. We’ve included five of those videos in today’s Saturday Movie Showcase. There a total of ten CTD AR-15 videos in the series. View them all on the CTD AR-15 Playlist on YouTube.

Then, as a closer, we offer another video — the Ten Mistakes to Avoid When Building an AR-15. Worth watching BEFORE you start an AR project, this useful video now has 2.1 million views!
