Was going to build an AR15, but started thinking about if I want to use the rifle for hunting down the road... varmints, hog, deer....

So I was thinking, if that's the case, maybe I should build a AR10 instead. Is it pretty much the same, or is there a big difference in the build?

Lot of guys out there hunting varmints, hogs and deer with the .223/5.56 AR's, I use a .223/5.56 for varmints and other smaller animals, and for deer I use my .300 black, but I no longer shoot much over 125 yards for deer.

I am in the process of getting the parts together for a AR 10, but I doubt I will use it for more than target shooting, I will continue to use my .330 black for that and if I go to Texas for hogs, I will use my AR 15

The last time I went hog hunting it was with a borrowed SKS. I was told not to use .223/5.56 for deer or hogs....

Really I've heard it both ways. Looks like it's a debate that will never end?

There is a big difference between building an AR-15 and AR-.308 because of the lack of standardization in the AR-.308 world.

In the AR-15 world, about the only variable is commercial or milspec buffer tube size, and I am seeing less and less commercial buffer tubes and stocks. In the AR-.308 world, you have to worry about different receiver compatibility, upper receiver rail height matching rail height, and magazine compatibility. Those are just the major concerns and doesn't get into the more minutiae that some people run into during .308 AR builds.

The right bullet selection in 5.56/.223 will do fine for hogs and deer, especially considering the size of deer in Texas (mule deer are a different story however).

Nope the debate will never end, because it is a debate, I would suggest anyone wanting to talk about Hogs and .223/5.56 head to the Hometown section and start talking to the other Texas guys, a bunch of them guys spend a lot of time hunting hogs.

As far as .223 for Deer, there have been a hell of a lot of deer killed with .22LR over the years, I would bet if we could ever figure it out, the 30-30 and the .22LR have probably taken more deer than the rest.

But at the heart of the matter, it just depends on what you are comfortable using, here in Montana, we don't have caliber limits so I know there are all kinds of calibers being used to do all kinds of things, I would never do.  I look at it this way, if the 5.56 can kill 3 million Vietnamese, It can kill a deer.

What all changes (in terms of parts) when you go up in caliber? Sorry if that's a stupid question, just trying to learn...

Bolt (sometimes)
Barrel and muzzle device (always)
Magazines (sometimes)

If you reload then 300BLK might be worth looking into.  Only caliber specific thing IIRC is the barrel and muzzle device

If you don't reload then look at building an AR in 7.62x39.  You'll need caliber specific mags for that one

AR-15 is easier, all parts are basically the same and interchangeable. While there's different AR-10 designs, so you need to be careful what parts you buy because they may not fit together.

No I don't reload. Sounds like it's just the upper that would need changes (Barrel/muzzle) and maybe the bolt. The lower works the same across the board?

I probably asked the original question wrong. The real question should be the differences in building a AR15 but in a different chamber than 5.56/.223

Yeah the lower is more or less the universal components.  I say more or less because with some 7.62x39 ammo you need a stronger hammer spring to ignite harder military primers.  

AR's are like the Legos of the gun world.  You can build a myriad of different things out of them and use the same lower....just a small sampling off the top of my head

22LR
9mm
FN 5.7
5.56/.223
.204 ruger
6.5 SPC
6.8 Grendel
7.62x39
.300 BLK/Whisper
.458 SOCOM
.50 Beawolf
.50 BMG (not semi auto but there is a bolt action upper out there)

and plenty more niche calibers and wildcats can be had if you have the coin.  If you want to swap calibers it's often as easy as just pushing out the takedown pins and slapping a new upper on there.  Sometimes you need to play with buffer weights, or in the case of 9mm throw a mag block into the lower, but it's a very easy no FFL required swap.

There's literally ZERO difference building an AR in 5.56 vs one in 7.62x39 tool wise.

Thanks! Might lean towards 7.62. Might stay at 5.56/.223. Still not sure yet.  Thanks!

Get both .

I'm building two 7.62x39 uppers.  One as a pistol and one as a 16" middy.  I'm also planning on getting a progressive press this year or next year so a 300BLK or two will be added to the stable

Sounds like I plan. I've heard once you build one it becomes an addiction! I'll probably start with the 5.56/.223. Will progress up.

Sounds like I can just build separate uppers and swap them if I want to. But then again, I'll probably just build a completely separate rifle!

It can be.  With how cheap lowers are these days there's little reason not to just build another rifle rather than have multiple uppers.  Only reason I had more uppers than lowers was because I move a lot and space is a consideration....but once I got into 80%'s and fruity ghost lowers I sort of threw that notion out the window.
