question for SR762 owners?

I am considering a AR-10. Not sure if I want the S&W MP10 or SR762. Recently experiences with Ruger and a quick google search of SR762 issues scare me. Has anyone owned both? Is the Piston System in the SR762 worth it? Im not a brand loyalist to any brand so if someone has a better suggestion I welcome it. Keep in mind I am buying it to take to the range and have fun, not using it as a hunting rifle, I already have hunting rifles. Thanks

Yes! I like it

Hello

I have the Ruger SR762 and the SR-556 Takedown, both are piston systems. I like the piston system alot. I had an Armalite AR-10 (gas DI) years ago and always hated cleaning the BCG. I still have to clean the piston but its much less stuff to clean and easier.

Question do you plan on running a suppressor? If so I think a piston system gives you more adjustability especially if you want to run a wide range of ammo from .308 to 7.62. Keep in mind .308 is a hotter round than 7.62 NATO loading and with a suppressor 308 can way over gas a gun.

I did not have any issues with my SR762 out of the box. I did have a few issues with it when I ran it suppressed. I ended up fixing that with a heavybuffers.com 8.0oz buffer and spring. Since then I've have zero issues. There is a thread on this site (from me) with pictures about that issue.

I've run the gun on all gas settings (0 to 3) and can say that IF you run the gun on gas setting zero (no gas) with full power loads then it is difficult to manually extract the round. If you use subsonic ammo (like Atomic) it's not a problem to extract. I only do that when shooting with a suppressor. With the suppressor on the gun, I run it on gas setting 1 when it's off I run it on gas setting 2.

My sr762 likes Sig Match 308 ammo. See photo for 100 yard 5 shot group. I've been able to hits 12" square targets out to 300, 400 and 500 meters with it.

So yes! I like mine a lot.

Thanks,this is quite helpful. The setting the gas system for different grains of ammo is what is turning me off to it. I do like the fact that piston system is easier to clean. As far as running suppressed.....if Trump fights for the hearing protection bill that the NRA is pushing and gets i passed, i will run suppressed. I hear that getting the paperwork to purchase a suppressor is a PITA

The paper work is not bad, its the wait that drives me nuts. I had to wait 9 months. Looking back on it, yea its a pain but worth it. You have to buy it, do the paper work, send it off and then forget about it.

As far as gas settings go #2 (at lease for me) always worked no matter what ammo I was shooting un-suppressed. Suppressed I shoot with gas setting 1. The heavy buffer made a world of difference, I was worried it would be too heavy and not fully cycle when I ran without a suppressor (setting 2) but I tested it with several ammo types and had no problems at all.

The attached photo is all of the ammo I tested. If you do get the SR762, I recommend cleaning it before you shoot. I also like to over lube my stuff for the first 500 rounds. It's a bit messy but I feel it helps break the gun in and polish parts. It might take longer but I'm in no rush.

Took mine to the range yesterday for the first time. Used Tulammo and below is what I got out of it. Shot it at 300 and 600 yards. Had to find my way in at 600 yards.

One thing I would also consider is do you plan to customize it to your liking? If so you would be better off with a direct impingement dpms lr308. This is the most prevelant platform, and by far has the most available parts compatibility in the large frame ar arena. The dpms lr308, bushmaster xm10, fulton armory titan, aero precision m5, knights armament sr25, and many others use compatible parts.

I have shot the sr7.62 and sr 5.56 they are nice rifles as is, but remember that gas systems of the piston nature are proprietary, which means you have to get replacement parts from that manufacturer.
The lr308 uses alot of the same parts as the ar15, so parts are cheaper and everywhere. As far as running suppressed, you can add a SLR sentry adjustable gas block and regulate the pressure the same as a piston. Cost $100. I have 2 set up with this gas block. The direct impingement has the potential to produce better accuracy due to its free floating capability.

Do not misunderstand me, I am not trying to get Into a discussion of which Is better, and why. They are both equally useful, and have a huge following.
I just feel if you plan to keep it as is, then a sr762 is great for some, and will do well. If you want to change it to your liking, want to build a second upper, or drop weight, change barrel length, or calibers the dpms lr308 pattern is the best option. Sr762 around $1500, oracle dpms $750. You can spend the other $750 to upgrade to your tastes.

I would like to own a sr7.62, but currently I have 5 or 6 lr308 platform rifles I built to my requirements. They are more accurate than most, and I have several different calibers, from 308, 243win, 338 federal, 6.5 creed etc.

Here is one I built from a bone stock oracle, added a 16" free floated hbar, 12.5" midwest rail, magpul accessories, and topped with an eotech 512. Its capable of better than 1moa at 100 yards.

Here is also an mp10 I converted for a friend. Added this since you expressed interest in the mp10. Here is what it can become. 15" rail, strike fire 2, and 3x magnifer, claymore compensator, and several other mods.

The Ruger SR762 is an excellent rifle. Had to send my first one back, but Ruger replaced it entirely. I have several of them.

Personally, I much prefer the piston system.
