All Things Guns

I see where my question was confusing….

I want to build another ar platform, but not in 223 or 556.

sean, i already have a ruger ranch rifle.

I built my last ar-15 from parts (no assemblies) which was a real hoot.

I'd be up for doing another, even starting from a stripped lower.

the little research i did shows some variations and different directions you can take with ar-10 and other ways of going about a .308.

it doesn't have to be 308 either….i'm just looking at ideas an concepts at this point.
 
I get it, your post was poorly written.
F
for composition.
I have nothing to offer here as I only grade papers and buy guns that other people build.
Speaking of which, anyone have a 1911 45 or 9 they want to sell?
Anyway, you should come to WF so we can pick on you in person.

Ironwood Designs does wood AR furniture. Good dude, nice stuff.

Anything not 5.56 is going to be more expensive to build. Not necessarily an issue, but something to be aware of. You have multiple options; 7.62 NATO, .300 Blackout, 9mm, etc.

Personally, if you're going with "I want it to be dead from 500 yards", 7.62 NATO is hard to beat. The only different between your 5.56 AR and the 7.62 one is the upper receiver, BCG and the barrel. Lots of options out there. I would build one from the Mega Arms receiver set, but it's pricey. There's a lot of options out there.

If you're going for "I want a .30 cal bullet", .300 blackout is a popular option. Ammunition choices are less, since you're dealing with a non-government round. Same as the 7.62, you're basically into it with a different barrel and BCG.

Really depends on what you want. Do you want long range performance? That means a longer barrel and some other goodies. Do you want a .30 cal bullet but the lightweight 200 yds and in performance of an AR? Maybe the .300 blackout is a better option, with a shorter barrel.
 
so....7.62....

I can build a 7.62 upper and run my existing lower?

I can run 308 as well right?

I was more or less thinking of building an ar-10.

here's the 15

No, not what I meant. I wrote badly.

A .308/AR-10 is dimensionally different than your AR-15, both upper and lower receivers. The process to put them together is the same, the lower parts kit is basically the same. You can't use a 5.56 lower because the magazines, etc. aren't the same sizes.

Functionally they are the same rifle. But a .308 receiver set is different because of the requirements of the longer/bigger round.

okay, that's what I thought!

so when I look at "ar-10's" it seems there are a few different design characteristics?

for the most part, the ar-15 is easy. you can almost take anyones lower pieces-parts and put them on anyones upper pieces-parts.

my research suggests that there is a certain "commitment" you have to make when beginning an ar-10 project.

does that make sense?

This info is not entirely correct when speaking of an AR15. The .300BLK uses a .223 as a parent case with a .30 cal projectile. When converting a standard AR15 to .300 BLK the only difference is the barrel. It uses the same BCG and mags. That is one of the reason for the popularity plus the subsonic rounds are great for suppressors.

This is true. The AR10 is not standardized like the AR15. Most use the same FCG but outside of that they have their differences and most parts are not interchangeable between brands.
 
Agreed on all counts, although I think there are better options for a 250 yd hunting gun.

I qualify at the range at 200, 300 and 500 yes with the 5.56. Is there really a need for a bigger caliber?

I don't always begin projects to serve a totally practical purpose.

I already own several good hunting rifle platforms. .270wsm .338win mag to name a couple

I have two uppers for my lower, one for varminting and a carbine set up for personal/home defense.

I'd like to build a larger-cal ar platform primarily for the following reason:

because I can.

the side benefit will be I will end up with a nice semi-auto larger cal shooter that I can whitetail hunt with (appropriate legal mag cap). There are a couple guys in my hunting group who are "gun lovers" up to the point of practical hunting applications. These jackasses don't appreciate anything beyond like ar platforms. I'd love nothing more than to have these guys catch me carrying a larger-cap ar platform afield next season(in legal wildlife code config) It'll probably fry their ass, and I would get some satisfaction from that.

so, what's a good starting point? .308? I'd like to build not buy, so I will probably start the project with a stripped lower and go from there.

any suggestions on who's configuration to start with? Is this strictly ar-10 territory? or is it an ar-15 project "in .308"?

thanks guys
 
I have a build sheet from a gentleman in NC that shoots 1000 yd matches with his Ma Ten. I'll post it if you want, but it's a $3k build. He sent me pictures of the .5 moa groups.

mag well in 15 is not long enough to accommodate x51.

This is full on AR-10 land.
Get one on the DPMS pattern, as they have the cheaper mags.
If it's full on no expenses spared custom
Ma Ten

If you want .30 in AR-15 upper it's going to be one of the calibers parented from the 5.56 case like .300AAC.

thanks.

I was getting ready to post a question you just answered.

it looks like the two common ar-10 architectures are dpms and armalite.
