How to Install Lower Parts Kit on a AR10 - Aero Precision M5 Kit 

I probably have more detent pins on my floor then most gunstores entire stock

Thank you x 💯! This is the most helpful and detailed video on assembling the aero lower receiver.

building my first AR....you gave me what I needed Nice vid...thanks

If anyone was wondering, don’t get the Geissele checkered anything. Learned the hard way. Just have to keep it for the next ar15 build

Go to a hardware store and get yourself a clevis pin to help install the drtents for the takedown pins. I use a ¼" for my AR15. It's basically a takedown pin with holes in it. Helps to hold the detent while you install the takedown pin.

I use the eraser end of a pencil to install the mag release.

Use a pencil eraser instead of the punch to install the mag release. So, if you do slip, the eraser won't scratch the finish.

FYI the Allen wrench is no longer included only the Allen screw is included.

Just an FYI for anyone looking to do this Aero AR308 build… While the lower parts for SOME AR308 receivers are supposed to fit, I’m finding out the hard way that several aftermarket-slick components actually do not. The only reason I purchased these products was because Aero was sold out of their lower parts kit, and has been for some time. Other retailers I searched were sold out as well. 1. Strike Industries AR-10 Takedown Pins. Front pin does not fit. Too wide. Packaging does state that this pin fits better on newer Gen5 models. Rear pin fits great. 2. Odin Works XMR3 mag release. Button is not long enough. You can get it to thread, but the lever will have too much play and will not function as intended. 3. Phase 5 XBR V3 bolt release. Functions, but fit is loose/sloppy compared to AR-15 fit in PSA or JD receivers. Hopefully this helps anyone looking to do this build. 😞

what is the last tool called for the back take down pin I don't see them on the website. holding up my build

There are definitely some differences from an AR15. I normally put these on Rumble though so screwtube won't cancel me.

What of your lower did not come with the rear take down pin installed?lol guess i will try to order one.

just curious on the ar tech mat you have

So i bought the palmetto lower kit to use with my m5 let's just say there's a few things not fitting off the rip I'm ready to give up that little screw for the smaller take down not here

Just did an AP AR15 lower. Gonna get an AR10 soon Edit… my lpk didn’t come with the .050 Allen wrench for the rear takedown pin, so I had to order one 😢

Would this lower work with a lr-308 upper?

Could I fit an N6 upper on this?

Are the sequels to this video up? I’m planning to start my 308 lower build tonight.

😍😍😍

Random question but do you know what size Allen key the screw takes for the rear take down pin? I’m having trouble finding one that small. Thank you

When I put the rear detent in, the spring has so much pressure I can barely get that screw in, and then there's so much pressure on the pin that the only way to get it to budge at all is a punch and mallet... think I just got a fluke?

What size is that Allen for rear take down my kit didn’t come with an Allen

What is the Allen key for the bolt release? I ordered the lower parts kit but it didn’t come with it.

nevermind about that rear takedown pin LMAO

Are there any other AR10 / M5 parts makers aside from Aero? Every time I search Aero is all I can find

whats the difference between the M5 and the M4e1?

Cool 😎 🇺🇸🧂🧂

Sorry but those hands are way to soft to an armorer.
