In this video, Caleb covers the second installment of the “How to Build an Accurate AR Series.” The video meticulously details the selection and assembly of components for building an accurate AR-15, including:
-Choosing a lower receiver with a tension screw to remove any play between the upper and lower receiver.
-Full detailed installation of the lower receiver components
-Why Loose Fitting Components Are an Issue
-LAW Folder Installation
-How Using a BCM RMS Will Help With This Build
-Stock Selection and Installation
-Bipod Installation
-How to properly mount an optic, full video here-
-Properly Adjusting the Tension Screw

I must apologies that this one is a bit longer than it really needs to be, but I wanted these videos to be a one stop shop for a new/novice builder as well so I run through the basics pretty thoroughly. Feel free to skip around if needed! Oh, and for a detailed optic mounting video, check out-
Never seen something like this built. This is a great vid!
cant believe u didnt use the radian talon ambi 45 safety. They are by far my favorite safeties, nothing is close.
I used a front pivot pin too for every build I've done. That trick you had is either black magic or years of experience. I normally launch at least one detent pin on every build. I don't know how you do it, but I'm going to give it a shot.

Hell yeah 🅱️aint is de way🤌
Before installing the trigger guard pivot roll pin, I recommend putting a little anti-seize grease on it. I like your idea of greasing the safety detent and spring before installing them. Also, your technique for installing the forward lower receiver pivot take-down pin is clever.
My favorite trigger is my timney 3lb single stage
What are your thoughts on lapping the upper receiver?
Great vid thanks!
I enjoyed and still do these videos just like the many made in the past, wanna see more range and zeroing as well as Steve phosphate and re finish pistol slides!!!!
For some reason I feel like I’m home every time I watch a Brownells video.
Like Caleb is my rich cousin from my mom’s side that lives out of state.
Even though I don’t see him often, it’s always nice to catch up on video.
Great video keep them coming. Got a lot of info off this!
Great Video 👊
I keep turning it up to hear your instructions, but the intro music keeps playing through the whole video. I think it should maybe fade out after 15 or 30 seconds? Love the videos.
If it helps at 47:55 into the 51:14 min video, he starts talking about the thing that made you click on this video.
You guys have the link for that master parts kit?
Gnarly…I'm on board
Show us when you paint it man I want to build one o these with MPVO and a red dot piggy back. How heavy is that sucker I know it does not have to be light is a SPR.
The offset on the scope is driving me crazy. Why not put the mount forward on the upper receiver and even the gap somewhat?
The "problem" with AR-15s is that by the time you get all the upgrades you want, you have enough "spare parts" that you can build a second one for just the cost of a stripped lower!
About time Brownells has Springco.
It would be awesome to see you take it to the range….
I spoke too soon!
😂😂😂
Looking forward to range day!
Isn’t that the FCD safety?
