Difference between the AR 10 variations

Dpms makes LR 308 rifles, which are very close to sr-25 rifles. The only major setback will be upper/lower connection.
Get a paired combo and everything should fall together fairly easily

>>32588496
Do not support the current ArmaLite, they are garbage and completely unrelated to the original other than the name.

>>32588496

Yeah, there seem to be two "sizes".

The DPMS (which PSA brand fits)
and
The Armalite.

The LR 308 is the DPMS term for AR-10

>>32588604
>The only lightweight AR10 options are DPMShit and ArmaLite
>You will never own a Portuguese model AR10
Feels bad, man

>>32588496
AR-10s are not AR-15s.

there is little standardization and you cant easily build a gun by sourcing parts from different manufacturers/sites. Everyone kind of does their own thing

with AR10s you should buy a whole rifle, then put pieces on based on what you want.

Buy an SR25

>>32588757
This

is it strange that I want to build a .308 AR set up like a normal AR carbine?
Like with a 16" barrel, collapsible stock, not set up for precision, etc.

>>32588757
That's the only 308 I haven't looked at yet

>>32588687

This nigga here. The only thing that might come close is the SR25/M110- and that's due to contracts to Uncle Sugar and friendly parties. And KAC prolly owns the entire technical/data package lock, stock and barrel since no other company has or will offer SR25 type rifles under government type contracts.

And one of the problems with these rifles is like their 5.56 counterparts is the issue to make them run w/ a can... reliably. Maybe that's why people look at the HK417 so fucking hard- that adjustable gas port/piston does allow some greater leeway if you want to run a gun suppressed.

>>32588687

Mega MATEN AR-10 is pretty good if you buy the two receivers together.

Why is it so hard to find parts for the AR 10, even from their own website?

>>32589076

I had a Palmetto State Armory AR-10 kit rifle with Palmetto receiver. The kit was $700, the receiver was $100. Both were on sale.

Not bad for an AR-10. It worked perfectly, the only thing I had to do was install antiwalk pins. It was very accurate but kinda boring to me. I have a PTR and a FAL plus a Rem 700 AAD-SD so it was a fairly redundant rifle. I traded it for a Arsenal SAM7R with lots of extras.

>>32589272
they are really more of a complete gun seller
Armalite and DPMS also use different barrel nuts iirc

>>32589272
Don't buy from them, dumbass.

Seems a lot of the SR 25 guns are going for 3-5k. I was hoping to stay in the more 1.5k range.

They are very nice rifles though, and I really like the fact the military uses them.

>>32589644
>>32589756
some of that cost has to be going to R&D
they are the original pioneers of the system and from what i can tell, are continually refining it

>>32590698
Lol? Continue refining what? There is no more innovation from KAC. They're like an American HK, but with less quality.

>>32591141
Nah, you don't know shit.

>>32591467
That's funny because I own an SR15E3 and an SR25 with MAMS. What the fuck do you have?

>>32591495
An SR15. If you think that KAC is lower quality than HK then you must not own any HK rifles.

Hey guys, I appreciate all the replies so far and there's a lot of useful information here.
Is there anyway to build a sr 25 for around 1,500$?

>>32591523
I don't own any HK rifles, that's correct. But I'm not happy with my SR25, and my SR15 performs at the same level as my DDM4, which costs half its price.

>>32591589
No.

>>32591600
What DDM4 do you have or where did you get ripped off for an SR-15? DDM4V7 LWs are like 1500 bucks and SR-15 Mod 2s are about 2100. Sorry you aren't happy with your SR-25, I don't have any experience with them. What's wrong with it?

HK rifles are ok, typical military quality rifles. The MR556 is a fucking joke.

>>32591650
V11. Shot show special from my dealer. I paid 1200.

My SR25 doesn't like certain ammo, and its accuracy varies widely over different ammo manufacturers. I'm talking about fgmm vs black hill vs hornady superformance, things at that level.

>>32591609
Should I go with a DPMS then if my budget is 1,500$? I intend to upgrade the rifle over time.

>>32591708
Sorry, I don't know. I don't have any experience with guns in that price range.

>>32588687
>there is little standardization and you cant easily build a gun by sourcing parts from different manufacturers/sites

Buy a matched DPMS pattern upper/lower (note your rail height as either high or low pattern). buy a barrel with a DPMS extension. You can buy a bolt and check the headspace yourself (you may get lucky and it could be fine) or you send your bolt to the barrel seller/maker and have them give you a barrel that is headspaced to your bolt. You can also use any AR-15 trigger or extension tube. Not that hard.

>>32592042
So the DPMS is a budget rifle but good enough to pass?

>>32588496
There are now also small frame .308s. If I was going to build one that's what I'd do.

>>32592113
It's a DPMS pattern rifle. It can be anything from Kreiger barrel 600 dollar matched receiver to complete shit if you want it.

>>32592225
There are just a few, and none come as parts, all prebuilts, afaik

>>32593802
There are some parts. Just not many. SLR and Midwest make rails for them and Mega I think sales the receivers

>>32591589
Live Free Armory, Armalite DEF10, Savage MSR10, Alex Pro Fab LR308, etc.

>>32594309
Mega has a small frame MATEN but only as a complete rifle.

>>32588496
Armalite's store seems to be in the midst of an overhaul. Typically, you can buy the parts from places like Rainier or find a generic from Brownells or the like.

As for DPMS, there's like 4 different specs of DPMS. Three types of LR-308 (low, mid, and high height receivers and G2) and dozens of other manufacturers making somewhat-compatible parts.

Personally, I have two AR-10's from Armalite and am fairly happy with them. The magazines are great and no issues yet with parts. I've bought a few from Armalite.com. One tip--get the model number of the part you need and Google it. You'll usually find 2+ other retailers selling it in stock. Also, if there's a local Armalite dealer, they can probably get any part in the catalog regardless of what the site says. And many parts are cross-compatible with AR-15's (most of the small parts outside of the bolts) or LR-308's (usually as an assembly). Only PITA really is handguard compatibility--which is limited since it's basically Armalite & RRA using one handguard spec.

As for the current Armalite company, they're not the same Armalite that invented the AR-10 or AR-15. They are now a brand of Strategic Armory Corps--who makes high-end brands like McMillan and Surgeon. The rifles themselves are still made to good specs and newer models do pretty well for competitive shooting.

>>32594468
Thanks for the information. Gives me some hope for the AR 10

Could I take this rifle
https://armalite.com/shop/ar-10-series-defensive-sporting-rifle-california-compliant/
To start with then over time upgrade the components? I assume that all the parts can be changed out over time.

Who makes good quality lowers using the DPMS measurements?
I wanted to start a build using aero precision parts, but they are never in stock so now I'm looking for alternatives.

>>32589644
I've been weighing an AR-10 purchase, and I keep thinking about my applications for it. I keep going back to Ruger Precision Rifle

>>32595728
The only advantages I can think of for the RPR is the side-folding stock and it accepting AICS (and maybe some M14) magazines. Everything else is a drawback in my book. The integral 20 MOA rail (I'd rather 0 MOA--for better compatibility with the handguard), proprietary action (nobody sells Ruger bolts; AR-10 and LR-308 bolts are available and in some cases interchangeable); proprietary trigger (versus drop-in most AR-15 triggers); 20" only barrel (versus selecting models between 13" and 24+").

the differences in AR10 recievers are the angle of part of the lower that the buffer tube screws into.

since Ar10s are serious money and should always be built to be DMR quality rifles. You should always get your receivers in matched sets from the same company.

>>32596014
>>32596014
Also the distance between pivot and takedown pins, the bore height, rail height, barrel nut threading spec, and barrel extension spec. The parts are not exactly the same but some parts function in both--like you can use a DPMS A2 buffer and A2 spring in either; the dust covers and most small pins interchange; the charging handle too; the barrel extension and bolt are paired and typically the bolt/carrier are also paired. For the lowers, the Armalites use a different mag release and bolt catch and the receivers tend to be lighter (DPMS has a habit of making their receivers beefier for no reason).

The AR-10B's have a longer-proven magazine but are more expensive. One cool way to reduce build cost is to use a DPMS barrel, bolt, and bolt carrier. Then use an Armalite handrail (Armalite themselves put out a fair few decent models for good pricing---better than most 3rd party pricing and competitive with Midwest Industries) and stock/buffer assembly.

Armalite built the upper on this pictured rifle.

>>32596444
Very nice, thanks for the information.

>>32593999
Double check again because I didn't run into anything major which didn't fit, and I had a lot of parts rotating through for months trying to squeeze accuracy out of the thing. Everything DPMS tall-receiver spec fit.

Had a JP bolt carrier and a DPMS bolt carrier, went through two buffer tubes and three handguards (DD Lite, Troy TRX, Troy MRF). All my triggers fit, all my SR25 and PMag20s fit, two barrels from Rainier Arms fit. The only thing that didn't fit was a Magpul MIAD grip, the original 1.0 version was not relieved for .308 receivers back then. The new 1.1 versions are, but I just filed the grip to fit.

>>32596858
>Double check again
I meant you have to get the upper/lower set. A DPMS upper will not fit an MATEN lower or will an upper or lower from an AR-10 fit a MATEN upper lower.

>>32591708
if you wait for deals you can build a nice rifle for that. i did mine for 1400 but saved about 250-300 this way
>labor day
>4th july
>black friday
>xmas

So I just got off the phone with Armalite regarding why they seem to always be out of stock and they said that due to the recent elections and past elections, there has been this minor state of panic in the AR world and they are getting nothing but full rifle orders.
They probably won't have parts until end of spring. So it sounds like I might as well save up for one of their nicer AR 10 (2000$)

>>32599520

>>32602289
I don't care what the military adopted. Piston ARs are retarded. Jim Sullivan says so and apparently Stoner thought so, too.

>>32588687
This, you can't start building an AR-10 with anywhere near the amount of unconcern you can with an AR-15. This is also why it's become standard to make as many parts on your '10 builds share commonality with '15s.

>>32602289
The csass contract is waaaaaaaaaaay to small to replace the sass contract

>>32588496
Does anyone know if somebody makes an A2 configuration, Armalite spec AR-10? I am thinking about ditching the AR rifles I own for other stuff, but an AR-10 A2 would actually make a really fun range rifle.

Bought this a couple weeks ago.

It's Armalite, but how hard is it going to be, to find parts for it?

It's a Matrix Arms receiver set, $400. Some anon told me that they make the receiver for the Ruger 762's, so I think they're quality.

>>32604187
That's KAC spec, not armalite
And easy peasy

>>32604187

>>32604356
How can you tell? I'm stupid.

>>32604357
Will do. I'm considering 16"-18" barrel but I'm not sure yet.

>>32589644
Consider the sig716, I own one and I've shot multiple (friends own them too) and every time it's performed amazingly.

>>32588496
LR308 is DPMS pattern. You will have a much easier time finding DPMS pattern parts than Armalite. The differences between them are cosmetic design choices, functionally they perform the same tasks equally well.

That said, some barrel makers only support one pattern.

>>32588604
This, todays ArmaLite is nothing. To take on the name and not be on the cutting edge of new developments is kind of a sham. Like Colt, they are riding on an an old design and not really innovating with it.

>>32588687
I built mine easily enough. Granted it took a while, but that was mainly because I waited for good deals on parts.

Lower needs to be compatible with your upper. Upper needs to be compatible with barrel and barrel nut.
Barrel nut needs to be compatible with bolt carrier group and hand guard, and to a lesser extent the upper for rail height.

After that, you only need a buffer spring, buffer weight, mag release, take down pins, and muzzle device. The rest is compatible with AR-15.

I realize it all sounds complicated, but it is nowhere near as bad as it sounds.

>>32588865
Kind of? I somewhat wanted one like that when I first got into guns. I decided against it when I realized that I'd have a lot of extra weigh for compromised ballistics.

I have to admit a short 308 is pretty cool in theory. Just realize its an expensive blaster. Its your money though.

>>32588992
HK is not the only piston in the game. POF springs to mind as well. There are also plenty of DI adjustable gas blocks as well.

>>32589076
>>32589146
>>32589272
Because they don't want you to build it. They want you to buy it so they can charge more.

>>32591589
SR25? No.

Something similar, yes.

You won't have the roll mark. You will probably won't have an as accurate gun, though it will probably still be more accurate than you are capable of.

>>32591708
Yes. DPMS is more affordable. Parts are more widely available for when you do decide to upgrade as well.

This.

Observe my AR15 with my uncle's repro AR10B. There are a hell of a lot more differences than you would think.

DPMS is the closest thing you are going to get in the AR-19 game.

>>32601896
The HK is going to wither on the vine in the Army, and then they will choose another.

They won the competition in April, but the contract they signed for the competition has no minimum value and no orders have been placed. The only rifles the Army has taken possession of are the ones that participated in testing.

I thought hard about building one but it seemed too laborious to hunt down what matches what, ending up with parts that didn't fit, etc.. so I just bought a Bushmaster XM-10 MOE (model no. 90828) because it had everything I wanted (triangular stock, chrome-lined chamber and barrel, threaded barrel end for my suppressor) and was assembled, of course.
I did buy an upper parts kit for it from Fulton Armory, which also has AR-10 stuff.

I later found the Ruger SR-762 which had an adjustable gas system, which might be useful to have.
