Aero M5 Build Plan

[Joshua]

I've spent the past few weeks reading up everything, and this is what I have so far. This is tentative. Naturally things may be substituted as things come in stock or go on sale. This is my first rifle build, so any input is great. Purpose is primarily hunting SC game. I would like stay under 2k including optics. Thanks!

Part of this doesn't display as intended on mobile. The italicized text is supposed to be together.

Consider beefing that up a bit to the Armalite kit, actually showing in stock right now:

An Armalite Kit is compatible? I though AR-10 products are a no-go on dpms high pattern?

That part is, as a kit, it's a better system with a little heavier buffer. The high pattern you refer to would be the receiver rail height, critical when choosing a handguard but nothing to do do with the extension and buffer. There are very few hard and fast rules with this platform, mostly lots of exceptions with exceptions to those exceptions. The search function here is your friend, hours of reading to be had on what works where....and what doesn't, I've added a bit there myself 

[Joshua]

It's $5 cheaper too!

What JT said. Get the Armalite kit.

16” barrel and 12” handguard will cut weight where it matters most, forward of your pivot point. It will feel like you took double off

^^^   Swing weight, right there.   less weight, further forward, and it does make a difference.  16" barrel will be able to hunt anything you want with it, too, with plenty of ft/lb of energy on target.

Thanks for all the feedback! I greatly appreciate it. I forgot to mention that I do plan on putting a sling on it. I don't think that really changes anything. Unless I misunderstood the parts already have sling mounts. Next I have to look into optics.

[Joshua]

Buffer tube should be delivered today!

Safety is pointed the wrong way.

I just caught that last week on another build...   I was ready to pounce, and read yours...  

[Joshua]

Oof. Thanks for pointing that out. Never would have noticed.

[Joshua]

I'm glad I have people who know what they're doing making sure I don't blow myself up.

Dang...I thought I was the only one to fall asleep during my build (LMAO).  At least it wasn't difficult to flip around!

So I go to screw the buffer tube in and the bottom of the tube does not orient properly when snugged up with the spring retainer. Is this just a simple add some spacers fix?

I assume you are referring to the pin that retains the buffer. The buffer tube does not have to be up against the pin, as long as the tube is far enough over the step in the pin to prevent launching it into orbit you are good to go…

Pics of the dilemna are gonna be required.  We already know you can post pics, too.  Show what you're talking about here, and help us help you.

I got the tube pointed the right direction, and the buffer retainer is held in place. Hopefully it looks correct.

[98Z5V]

Looks good.

Is the buffer tube holding the retainer pin down or the buffer itself? The tube doesn't appear to be screwed in far enough.

One more turn, and that receiver extension will be sticking out further than the lower receiver.  Which is not good.  It's fine like it is.

It's being held down by the tube.
