    The questions went to Ruger's first-level customer service dept and it sounded like they just wrote back to say they were being referred to someone in technical support. They didn't just flat out not answer the question.

    I would never expect a company the size of Ruger to have their first-level customer service reps trained on (non-recall) technical questions, especially on a pre-release rifle.

    Comment / question:

    Hello,
    I have a question about the new SR-556 rifle. Does Ruger HP/ MPI test and inspect their barrels and bolts? What type of extractor spring and insert is used? Is the castle nut staked? Thank you.
    v/r,
    W. Larson

    Just to interject.

    Test your barrel. I doubt it will be 1:9.
    You will find in a lot of "1:9" factory barrels, that some runs will be closer to 1:8, I had an Armalite 1:9 some years ago that was actually 1:7.9 something.

    Just because your 1:9 marked barrel shoots 75-77gr ammuntion does not make it a FACT that real 1:9 guns will do so, it means your gun will under the same conditions you tested it.

    Cost Known

    I am not a dealer, but I have some connections- dealer cost for this rifle from a large distributor in Ohio is around 1300.00- they are now taking orders

    I will check it and see. All I know is I was surprised that it shot as good as it did with them (even though it has been a very accurate barrel), reading all the info suggested otherwise but it reinforced the idea of actually trying something before you dismiss it or accept it. Hard to beat personal experience.

    As for the conditions, I thought it was in the fall but notes show it was Sept. and 90 degrees when I grouped them. Load is 24 gr of TAC running at 2700 fps. I will certainly try again in cooler weather.

    Yes, it should work fine in 90 degrees F though no one can purposely buy a 1:9 twist barrel with the intention of shooting 75 or 77 grain ammo as they might be called out at night or in the cold.

    What you should be rolling your eyes over is: the dumb questions asked & the obviousl complete lack of understanding of piston v. DI systems.

    First, the type of extractor spring and insert used matters for DI guns, NOT pistons, and it was never an issue except for the carbine-length DI system (did I make clear that DI v. piston = apples to oranges?)

    Second, HP/ MPI test & inspection of bolts applies to DI guns and is meant to prevent bolt-breakage in a DI gun, where the BOLT IS PART OF THE GAS SYSTEM!!!! In any piston gun, gas never gets anywhere near the bolt and it doe not act directly on the bolt to function the weapon.

    Honestly, these were not intelligent questions to ask about a piston system. Furthermore, spring/insert type or what quality controls the bolt goes through are NOT benchmarks for a piston-driven gun and are meaningless in the context of any piston drive.

    Why not ask they same Q.s of Sig about their 556 or Steyr about their AUG? The Ruger is NOT a traditional DI ar-15 or M4 clone.

    Why does it not matter for piston guns? It matters just as much due to fatigue life of the spring.

    Second, HP/ MPI test & inspection of bolts applies to DI guns and is meant to prevent bolt-breakage in a DI gun, where the BOLT IS PART OF THE GAS SYSTEM!!!! In any piston gun, gas never gets anywhere near the bolt and it doe not act directly on the bolt to function the weapon.
    This is not true. Piston guns are actually tougher on the bolt face/lugs than DI guns. There is no gas coming from behind to relieve pressure on the lugs before unlocking.

    Honestly, these were not intelligent questions to ask about a piston system. Furthermore, spring/insert type or what quality controls the bolt goes through are NOT benchmarks for a piston-driven gun and are meaningless in the context of any piston drive.
    Highly untrue.

    Why not ask they same Q.s of Sig about their 556 or Steyr about their AUG? The Ruger is NOT a traditional DI ar-15 or M4 clone.
    Because the Sig 556 does not have as many lugs and hence they are each larger and not likely to break. The M4 bolt has a lifespan of just 6000-1000 rounds, so it is critical to get one made of mil-spec Carpenter 158 rather than 8620 or 9310. Nearly all commercial bolts are made on 8620 and it is not good enough. I am not claiming the testing is critical though.

    Well I disagree and if the chamber is not a true 5.56 and you have a crappy extractor then you will also have extraction problems.

    I also think that having an HP/ MPI inspected and tested barrel is important. But that's just my .02 cents.

    I'm a little scared after reading that article... They researched which parts to build their match grade test rifles out of and bought DPMS across the board... I dunno, it just seemed a little "non-scientific" (read: Bubba'd) on the testing... or was that just me?
