New Ruger SR-762 rifle

  Ruger has come out with a larger version of the SR-556. This time in 7.62 NATO.....looks pretty good!

Cool. I really, really like it. But for $2k?

As for the piston, that's what I like about it. It works great in the M1A, the AK, SKS, the HK416, etc. This looks promising

Sure, it works in those platforms because that's what they're designed for. Again, I'll reference a FB thread some of us were talking on. Someone (Ogre, maybe) mentioned that the DI free-float configuration has the greatest accuracy. And there's nothing wrong with it.

The pistons in ARs tend to have issues more than a plain DI gun.

Personally if I was shopping for a .308AR for less than $2K I'd look hard at the S&W M&P 10. Otherwise I'm gonna save the money for a LaRue OBR.

I don't THINK I'll ever have to face down routers in the streets.

I should hope not. Mobs of rogue woodworking tools would suck to repel.

The AR design was not built around a piston. This means one of two things:

The piston system will be designed to be showhorned into an AR, which means that it is not going to be an ideal piston (think about an op-rod the diameter of a gas tube ... that's pretty poor from an engineering standpoint).

The design will be so altered that it is no longer an AR (which can be either good or bad, but it means that the known-good aspects of the AR platform are in question).

Add in all of the changes you have to make to deal with carrier tilt ... no thanks. I'm not saying it can't work. I'm just saying that it is easier to deal with the well-known (and small) problems of direct gas.

  I won't close my mind to it altogether. I'm very satisfied with my std DI AR rifles and can't justify the expense of switching to a piston set up. If I had the inclination I would switch with no reservations. I can't bash on the various well designed piston AR variations.
  The 416, LWRC M6, and the Ruger SR-556 have all steadily gained very good, solid reputations and continue to do so. They are all AR designs modified around a piston, as is this one, only in 7.62 NATO. I'll be waiting endurance/reliability tests from a few credible sources before I poo-poo it.
  As for the MSRP, real world, once the rush is over it'll be more like $1,750 or so.
  I find it funny that piston variants are currently being looked down on even as the designs evolve, by many of the same people that derided the DI ARs and begged Odin for piston guns not too many years ago.
  Yet now the very same vacillators tout the DI system as the one and only way to operate the AR Why? Because it is the popular thing to do.
  If for some reason one or more of the tactical gun culture's Cult of Personality Du jour figures proclaim piston ARs once and for all "The Sheot", so will the vacillators, as they scramble for everything piston.

I've thought about doing a piston build, because it's about the only major variation I haven't built yet, but the negatives of the piston far outweigh the possible benefits and fun of the build.

If you can play with Legos you can build AR's. I built my first lower in a downtown apartment with a claw hammer, screwdriver, and a razor blade. I bench vice and some special tools are required to build uppers from scratch, but lowers are super easy.

The only hard part is barrel/gas block/upper assembly. Everything else is literally, insert tab A in slot B. And the barrel isn't terribly difficult, either. You just need a (very) few tools.

If I were to get a piston gun in that price range, I would look at the Sig.

  I have heard it was quite easy to build them, I just have never ventured into it, but I think I'd like to build one in 9mm....... I think it's great that so many people build their own ARs!

 I have no knowledge of the SIG Piston guns, so I can't speak on them yea or nay. The three I previously mentioned (416, M6 and SR-556)  were other dept's guns that I've had the opportunity to shoot and discuss with the officers who were issued them.
  They all thought highly of them, but we all pretty much agreed that the piston guns and the DI guns were pretty much equal under most circumstances and that the big differences come when the guns have shot in excess of 500-700 rounds between cleanings or running suppressed constantly. Rifles running dry, dirty and hot is where the pistons guns might have an edge.
 ( As a side note the M6 guy ran a suppressor constantly with zero problems.)

The SIG 55X series works well, but it's heavy, doesn't balance well, and has a smooth but long and squishy trigger. I had a 556 and sold it for a loss to get rid of it. Not a fan, but that's my opinion.

So something crossed my mind while reading this thread. Are there any other DI guns out there? The only one I can think of off the top of my head is the M-16, AR-10 series of guns.

Very interesting from Wiki:
Quote
The first experimental rifle using a direct impingement system was the French ENT 1901 Rossignol B1 rifle followed by Rossignol's B2, B4 and B5. The first successful production weapon was the MAS 40 rifle adopted in March 1940. The Swedish Ag m/42 is another well-known example. Both the French and Swedish rifles use a simple system whereby the gas tube acts as a piston with a cylinder recess in the bolt carrier.
It is incorrectly believed that the AR-15/M16 rifle designed by Eugene Stoner uses a direct impingement action. In the Stoner system covered by U.S. Patent 2,951,424 Stoner specifically states that the action is not direct impingement saying ″This invention is a true expanding gas system instead of the conventional impinging gas system.″[1] Gas is routed from a port in the barrel directly to a chamber formed in the bolt carrier. The bolt acts as the piston and is sealed with small automobile-style piston rings. It is a gas piston system without an operating rod.

Yawn! Another AR in 308. And in excess of 2 grand? I would rather have seen a beefed up Mini-14 in .308 (finally) for a whole lot less money and appealing to a wider gun buying audience.

I am glad to see more .308 options.  But I am saving for a Broadsword, and this ain't an option.  It does look kinda cool though.
