Default AR15 vs AR10

What are the advantages of AR15 over the AR10/DPMS/SR25? I know as far as military goes the .223 has more control in full auto and lighter and more rounds of ammo. But since semi auto is our only option and 10 round capacity limit for both why not go with the AR10 with more power. If you had to choose just one of the two which one would you pick and why?

id say if i had to choose one id go with the ar-10...im still waiting on my POF .308....i think it also depends on the application. my ar-15 is light i can carry lots of ammo, ammo is fairly cheap. ar-10 a little heavier, better down range energyknock down power, less wind drift making it more accurate at longer ranges.

The ONLY advantage the AR-10 has over the AR-15 is that it fires a more powerful round.

308 AR's are not standardized so there are multiple brands that are not parts-compatible.
308's cost a lot more.
308's are heavier.

Advantages of AR15 over AR10:

To sum it in one word, overall costs. (ammo, parts, etc...)

Don't forget standardization.
Parts from any brand work on any other brand.

The Real AR10's Were bought by the Portuguese (As I remember) Military. They had a terrible reputation for blowing up. When we trained with them we teased them a lot and they were not happy to take them to the range........

Interchangeable is a great reason. AR15s are very versatile too. You can put a number of rounds through it by simply changing the upper and magazine. I've read that a lot of the SPECOPS have been putting higher power rounds on them and having great success. (6.5, 6.8SPC, etc). So if you want more power you can still stick with the AR15, parts are easy to come by, easily upgradeable and you can always upsize the round from a 223.

What's your budget? As already mentioned the AR-15's are standardized and one lower works for all uppers, allowing more flexibility, and there are tons of uppers and parts available for the AR-15. I want an AR-10 too but everything costs 50-100% more. There are two styles of uppers and lowers that aren't interchangeable. I want the knockdown of the 308 and the longer range (yeah I know you can build a AR-15 for long range, but it won't put down anything much over 2-300 yards) What are you going to do with it?

As far as the two platforms go, I prefer the AR-15. Lighter, standardized, inexpensive, etc.

As far as the two rounds go, I agree with your reasoning and MUCH prefer the .308 WIN. We only get ten rounds, AND that's SA, so my vote is for the more powerful cartridge. If I ever had to go for a rifle in an emergency it'd be my M1A.

That being said, get an M1A.

If cost wasn't a factor, I def. say go with a AR-10. I'm currently working on building another AR-10 SASS Clone. .308 is expensive obviously, so is the AR-10 rifle in general. You can figure on paying twice as much on an AR-10 as you would an AR-15. However the 'thump' you feel from hitting a steel target with an AR-10 was what sold it for me. They def. pack a punch, plus you can touch targets at longer distances. Here's my old AR-10:

Hey kingsnake, can i ask how you like that fsc762? Is it working out well for you?
Was thinking about throwing that on my ar-10, but wondering if i should get a surefire brake instead.

THanks

That should give you an idea of the weight differences. If you are looking for a plinker rifle for an AR-15, if you are looking for long distance shooting go AR-10. They are both great guns, but sharply contract with each other, so it's really a matter of personal preference. I for one like both!
I didn't realize the AR10 was so heavy, I was about to build one
that's five pounds heavier than my FN FAL

I guess I'll build an AR15 instead, I was thinking AR15/AR10 being close to the same weight

I just didn't want a girlie boy 22 caliber

If I had to choose one to own, knowing what I know, and assuming the reason I can only have one is because of $$$, i'd choose the AR15.
1. Versatile
2. Cheaper Ammo = More shooting = More proficient.
3. $150 for a .22lr conversion kit and you can have fun all day long with cheap ammo.

Go with an AR in .308 if you want to get out to distances 5.56 can not reach, it's that simple. You're looking at a bigger gun, a longer barrel, slightly more expensive ammo. My AR10T with 24" barrel is a beast compared to my AR15 carbine. Each gun will do some things better than the other can do. The carbine has an acog and red dot for fast target acquisition, while the AR10 has a big scope and bipod. Different tools for different jobs. It all depends on what job you want yours to do?

thats my big kicker for going for a ar15 vs ar10. i already have a good .308 bolt for long range work. just want something i can shot a lot cheaper at mid ranges and do a carbine class with, even thugh its going t end up being a 18"build.

AR-10 has a more powerful round= more range, better terminal ballistics...
that's the only thing going for it...
otherwise AR-15 wins in the price and compatibility categories...
