Ruger SR 762 lower compatibility?

[E304life]

I'm in the process of selecting my first "battle rifle" to purchase. I like what the Ruger SR 762 brings to the table, and it has good reviews. My question is, will the SR 762 lower fit other manufacturers DI uppers? I think the SR 762 uses the SR25 pattern lower, but I don't know if the lowers are truly standardized yet. If the Ruger lower can be used with other uppers, then that is a huge plus for going with the ruger platform.

PS,
Im considering all battle rifles, PTR91, SA58, M1a, FN17s, XCR-M.... so any suggestions on what to get are welcome.

I hear good things about the Ruger but if you are just going to swap uppers why not go with a different maker that has the upper you want? There are two major patterns, and several lesser, in the AR308 world. There is the DPMS pattern and the Armalite pattern. And there there are numerous other niche patterns.

As long as it is one of the big two then finding another upper will not be hard. If Ruger does their own thing then good luck.I am building my rifle on a DPMS pattern lower.

Also, don't overlook the FAL. It will not be as accurate as an AR pattern rifle but they are simple to use, have the best ergos or any battle rifle out there and are reliable under almost any conditions. Might be worth a look too. And cheaper...

Rugers are built on the armalite pattern receiver. The sr25 part only applies to the magwell no matter the brand. A dpms will not take kac parts even though they take the same mags. You can't put an armalite upper on the ruger lower without some internal modification for the takedown lug. The ruger is a completely proprietary gun except for the stock, grip, and lpk. No changing handguards, ruger is the only place to get bcg parts. If you like the ruger exactly how it comes from the factory then go for it. I thought I did but soon found out that there were a lot better choices for what I wanted. I went with a psa. Total with shipping and ffl was 1004 dollars and came with a 15" Midwest ff handguard. The biggest thing that put me off about the ruger was when I accidentally grabbed the gas block since its not hidden under the handguard. That and the gas regulator doesn't come out very easily after it has a few hundred rounds of carbon build up on it.

I don't have the intention to swap uppers immediately (if its even possible), but having the flexibility is very attractive, and adds value in my eyes. I have looked at DSA FAL's, and while they have great ergos and reliability, they are very expensive for being the least accurate battle rifle you can buy.

I wouldnt call it the least accurate. While it will not make tiny groups on paper it is a true battle rifle which means you will get 2moa which is perfectly fine for what it was intended to do. I have hit poppers at 425y using only iron sights with my parts kit FAL. That is plenty accurate for me.

As far as swapping uppers stick with either a DPMS pattern or Armalite pattern lower and you should be OK. There seems to be more aftermarket support for the DPMS pattern.

I don't know about compatability with other uppers by my SR762 is plenty accurate. Was just out this week sighting it in with some hunting ammo. Easy MOA groups at 100 yards. Pretty soft shooting as well. Actually kind of fun to shoot. Yeah, it's going deer hunting in a couple weeks.

I emailed Ruger, and they say that "the upper and lower are unique, and only our upper and lower will work together". That's not a surprising company line. I have no reason not to believe them; many 308 AR's are proprietary. I am still very interested in the SR 762, but now I know it isn't extra special

I still don't know what "battle rifle" I want. They all bring some unique characteristic to the table. I want all of them (that isn't realistic), but I need at least one high cap semi .308 in case the ban hammer drops. The problem is, i want this one rifle i could potentially be stuck with to be flexible; CQB to DMR, with high reliability, great ergo's, and low cost. Oh yeah, it has to look good too. I know I know, another guy wanting to have their cake and eat it too. I think I'm actually wanting two cakes...maybe three.

This may not be helpful in the least but have you considered calibers available for the AR 15 and whether they would satisfy future wants? Perhaps some flavor of 6.5, .300 or .458 might work. If you already own a lower, you could save a bit now buying only the upper and perhaps a stripped lower as the firearm (receiver) and magazines are the more commonly banned items.

If that won't work for you, I'll pass along that I've heard quite a bit of grumbling about QC at Armalite lately so research before spending and good luck to you.
