Thanks for joining us today as we teach you the “how to” on assembling / building your AR-15 stripped lower receiver. We take you step-by-step through the installation of the LPK (Lower Parts Kit), the Buffer Tube Kit and what tools you will need to successfully accomplish this at home. This will be the first part in a series of videos as we show you the entire product from beginning to end of completely assembling an AR-15 on your own. If this is your first time building an AR15 from the ground up, fret not… it’s not that difficult once you know the parts, and it will simply either “go click” if you’ve done it correctly, or not if you are unsuccessful at first. Take your time, have patience and have this tutorial video ready to help you along the way. And, if you have any questions, feel free to hit us up for advice, guidance, etc. on your AR build at home.

Buy Clevis pin from lowes —- 1/4" it will cost you $ 1.94
Beware I have three Panther Arms ap4 rifle kits in each of these kits are missing the same Parts the charging handles. They knew they were missing these parts when they package them, because they don't have any and I will have to wait a month and a half to get them or just go buy them. The trigger guard roll pin in all three kits are too large. Good job Remington. Oh yeah I forgot none of the dust cover doors will stay closed either
the video was helpful could of had more light when installing the parts to lower but overall it helped out thanks although I have to view a video on new York compliant
Where You been living? i only held a AR 15 Once in my life But the TRICK FOR THAT SPRING & DETENT iS TO PUSH A 1/4" DRILL bIT THROUGH THE OPPOSITE HOLE & hold the Detent in as you push the drill bit to Cover the Detent.
Then push the Pivot pin In up against the bit 'round side facing the Detent,,, Then when you're sure the pin hole & Detent line up Twist the pivot pin till it Captures the hole in the pivot pin & finish pushing the drill bit out,,, Now about that $10.00 off my next purchase,,,???
go to Gerber short stack. Com and purchase the river shore step
When you get to the pivot pin portion, use needle nose to push pin down on top of spring, push pin down with a small punch, then use a staple to wedge the pin down while holding the staple, lastly just slide the pivot pin through and remove staple.
overall a great video, used it to double check myself as I went along on my 1st stripped lower build.
Really I like the video the lighting coumd'nt get any poorer c-
The forward pivot pin can be installed using a razorr blade to keep the pin and spring compressed.
Great video it helped a lot….besides losing the detente pin for the bolt hold open, it launched into oblivion,Ill buy another. All the rest was done in the bathroom! I prefer my AK builds better suited for the big handed gentleman!
Great video, Thanks! I used an old feeler gauge to install the detint for the front pivot pin, worked like a charm.
Good info but TERRIBLE camera position. Trying to see the detail of how to do several things and all I see is your hand. Camera should be in front of you pointing down at the lower.
Where's part 2??
The safety selector doesn't have that snappy action to it even though I made sure the spring and detent were in the correct position.
You need better lighting but love your video thank you
for easy pivot pin installation get a Brownell pivot pin installation tool, it is not expensive..
i live in cali dumbest gun laws/ politicians on the planet what good it does since cali has some of the highest gun crimes anyway. just making things harder on the people who actually obey the law and we all know criminals obey the law to the letter
for the pivot detent, I found that using a bolt sized to the holes for the pivot pin put in through the other side creates a backing for the detent so that it will not drop through the pivot holes. Got it in in two tries.
use a razor to hold down the pin when installing the forward take down pin. Its easy to hold down that way and you can just slide the take down pin through with no problem. it makes quick easy work of what use to be the MOST annoying part of assembling a lower
Front takedown detent trick. I use one of my punches and put it through to hold the detent in place and then carefully push the pin in place from the other side. I learned this after losing one on my first build . Have not since knock on wood
I cannot believe you need one of those stupid bullet buttons. I am appalled that it is the law in your state. “Those who deny freedom to others deserve it not for themselves.”
Good video. Believe you misidentified one of the springs up front, but no biggie; one can easily figure it out. At 13:10 you have the problem that requires a special tool you do not have. The special tool you need is a 1" or 1.25" spackle spatula. It will allow you to hold the detent in and keep it in while you are trying to set the forward pivot pin..
part 2?? upload a part 2??????!!?!?!?
i don't see part 2 or any other parts of this series for that matter… D:
Good information glad too see I didn't need to buy a vise for this part , but I needed to run a 1/4 28 tap in the pistol grip hole them threads were very snug the bolt wasn't going to start at all ….
I'm going to start on my first 'project' this weekend. Thanks for the great video(s)! One suggestion, though. Since much of what you're showing is black on black and the things you're pointing out are small (easily hidden by the finger you're pointing with), how about using a laser pointer. Nothing special – just the kind cats play with. It would sure make it easier to see exactly what you're talking about.
Thanks again…
Now I get referred to another site for better pictures and information on what you just did? Where is the value here?
OK, second comment. I am soooo impressed you can identify all the parts. Wait, doesn't the documentation do that too?
OK, first comment, The kit obviously has documentation include in the box. Why didn't you show it?
good video, but some of your nomenclature is off i.e. "the bolt catch buffer, and bolt catch buffer spring" that is not correct, other than that it is pretty spot on good job man
Great video thanks. I just got done with my first ar. I looked at several videos but decided to build my gun with yours. It works perfect and your instruction was very easy to follow.
nice job, good refresher for me.
I like you video but you need some back lighting really bad. I could not see the parts as you were installing them;
aWSOME!!! MY LOWER IS NOW COMPLETE!!However I believe there is an easier way to install the locking pin that has a habit of shooting off. This video was most informative, thanks guys, I will refer you!!
Nice vid! As far as the pivot/takedown pin, I use the side of the blade inan xacto knife
Thank you very much, I was able to finish mine perfectly, My only advice is make it clearer for what you are doing, some of the things were a bit obscured..
where is part 2?
i cannot thank you enough for this, helped me with my first lower parts assembly build alone, thanks dude!
That's the wrong spring for the mag release its the bigger one
Great demo. Thank you for uploading. For installation of take down pins, I use an Allen wrench key to depress detend springs and slide pins in and slide Allen wrench out.
I stopped watching once I found out this was a CA compliant build. CA is the worst place to live if you want to own a firearm or any self defense weapon for that matter.
The first thing I would do if I lived in California is move to Texas. God bless Texas.
mmm… probably gonna need that damn bullet button wrench. crap.
Man, and I thought Illinois's gun laws sucked… I'd much rather live here than California… I feel really bad for you, man…
If you can't identify the parts without color coding you really awt not be building your own.
@TBP for the pivot pin detention pin and spring use a box cutter razor blade or piece of tape to hold the detention pin flush while you insert the pivot pin.
