so looking to make a AR\LR10
want a 6.5 or 7mm08 or 243. should i get a ar10 lower or ar308?
is the ar308 only for 308s? or are the parts kit, upper, etc classified as use for an ar308?
all the google threads I've seen haven't given a straight answer, at least for me

Howdy,

In my experience, AR10s are not modular and often proprietary. Example: I would not expect a Daniel Defense .308 upper to fit on a DPMS AR10 lower. This is the reality.

AR10 is the platform that will house the calibers that you are referring to. .243, 6.5cm, 7/08 and .308 are the same case.

If you build, find a lower/upper combination from the same manufacturer and make sure that they fit. I would try to look at one in person versus online.

I am not big on AR10s but I have owned and used enough of them to see variations.

Buy an upper in the caliber of your choice from Bear creek Arsenal and get a complete blem lower from psa, or just get a bear creek lower. Those are the lr308 platform and what I would go with.

I have an Armalite .260 Rem. It has a 24 inch heavy match barrel on it. It is very accurate, but is also very heavy with a big scope and it wrecks brass. If I had test drove one before buying I would not own an AR 10. They are not handy little rifles like an AR 15.

No need to spend over 600 bucks either. Lots of over priced stuff out there.

What a can of worms you've opened up here lol!

AR10 is the Armalite pattern, which is the lesser used type.

LR308 is the DPMS pattern, which seems to be the most used/copied type.

Rock River has it's own pattern also.

I'd pick one and use matched uppers/lowers from one manufacturer imo. Probably Aero if I wanted something pretty nice, Bear Creek or PSA if I wanted something cheap.

All of those are going to be heavy pigs I wouldn't want to use much.

I have a pair of 243's that are my go-to's, they are the DPMS G2, which aren't made any more of course. But they are smaller and lighter and very accurate, if you can find one. They're getting tough to find on GB even. Many said they were too expensive and went with the old clunky style, but I've since read that they don't use theirs anymore, whereas I use mine lol.

Now Ruger has a SFAR 308, which is a 308 that's the same size as an ar15. If I was buying something to hunt with, that's probably what I'd do. At some point, someone will come out with Creedmoor and 243 barrels I'd bet and you can change it out.

Just one man's opinion, and worth what you paid for it lol.

I won't hunt with any AR that isn't a sidecharger anymore either. So much better for loading and unloading.

You have all the good advice here there is. I researched before I built my first one and had no solid ideas so went with Aero everything except for the barrel. Aero enhanced upper parts are very easy because you don't need to worry about shims or timing the barrel nut. I'll take that back, an AR10 barrel nut does need lined up.

I’d probably just get a psa blem.

thanks all for the info

im leaning towards a complete BCA for the price aspect and just to try it out. and they have a 243 upper i can swap out if i like it. worst case, i can upgrade some stuff. akin to buying a rock island 1911

Get a sidecharger and you won't look back.

already in the cart

I have two.

The problems i have had, and that are in front of me are numerous.

I do not recommend the platform at all.

Unless maybe you are hog hunting from a side by side, and or, you have a lot of money!

The AR15 platform has many nice calibers for short/med range varmint hunting. For long range.... You will get bucked off the target anyway with the AR-308, and follow up shots way out are hard to make on moving targets.

May as well be running a bolt gun with a caliber that is smoking hot!

Seems the AR308 would be good if the 300lb communist hogs from Texas where parachuting down in your back yard and you needed some serious fire power up close.

I moved to an AR10 in 243 this year and it has performed PHENOMENAL!!! Most successful competition hunters in my area are also running AR10 in 243 or 6creed.

Not sure what brand/calibers your running but I couldn't disagree more. I'm running a "cheap" PSA upper and lower, Geissele SSA-E trigger, adjustable gas block with a 22' Xcaliber SPR contour barrel (plus 2" gas), weighs 9.2 lbs..

The gun shoots 58vmax at 3700ish into solid, repeatable .6moa 5 shot groups. It has very very little recoil. Follow up shots are stupid easy, you can plainly see coyotes drop in the scope. It has also ran 100% so far so knock on wood!

I shot over 100 coyotes with it in 23 nights, here is the link to video showing the kills and how it performs.

I can't speak for other brands but I would buy exactly what I have again in a second.

Ruger has a new lightweight AR 10 out, hopefully they make it in 243, POF makes another but its really expensive. I shoot a 6 DTI but if I was doing it again now. with the advances in the AR 10 to keep it lighter, I would likely just get one in 243, suppressed autta make a pretty awesome calling rifle.

with the side chargers, I don't like the extra metal removed in the receiver. I load and unload my gun everytime doing stands. the regular charging setup is fine with me. plus the brass catcher I run would hate a reciprocating charging handle.
