    surfer1105,

    quote:Mainly for long range shooting and range shooting.

    It would help us immensely if you could add some parameters to this statement. Not all of use the same or similar definitions for 'long range' or 'range shooting'. For instance, my long range starts at 1,000 yards and goes out from there. Or my range shooting can start from a bench with some pretty good rests or from a matte on the ground with a bipod depending on which type of competition I'm practicing for.

    I'm not one to place a lot of emphasis on the operating system; gas impingement or piston. It's a better bet that the rifle made with the best parts and assembled for accuracy will beat the competition when Match grade ammunition is employed. Without these, you have an 'also ran' or generic rifle only capable of basic 1-1/2" accuracy at 100 yards. This is about what the two rifles mentioned in your post are capable of overall. There can always be exception but the world of long range and competition are not built around exceptions. You need consistency from both the rifle and the ammunition and especially the shooter. Remember that the glass you choose will be as big a decision as the rifle itself.

    Best.

    Good afternoon,Thank you for taking the time to help.Im a vet. who has rekindled my passion for rifle shooting that I once enjoyed during my service time.after a round at the range with a friend and his ar15,308cal along with the smell of discharge ammo,
    im longing for those days again with my own weapons. I enjoy med.range precision, mostly bench shooting....and dabbleing into 600+yd. shooting as i get better. Probabley with 308 winchester ammo, and direct or gas is where the price seems to spike for the Sig. Thanks again.

    Why are you limiting yourself to those two rifles? There are many other 308's, some following the AR-10 profile and some not.

    Even rifles of the same model from the same manufacturer will have differences in accuracy.

    If all you are after is accuracy, then I'd look at the M14 type rifles, there are many out there that are configured for national match shooting.

    You can probably also do it with several of the AR-10 variations. Just not sure of the state of the art as far as the AR10 and accuracy.

    I'd only worry about piston vs gas impingement if you were planning on engaging in two way range exercises, and if that were the case I'd go for reliability over accuracy and choose a FN-FAL type.

    I'm a new b to the ar plat forms, currently I own a Bushmaster ar15 223, and a sig 40 P229. The choosing of the sig is based on my pistol and its performance at the range,the tight build and overall feel. It was bought for 300, so with YouTube reviews on the716 I took this model under consideration. Keep it in the family. The Smith and Wesson brand has been in our family, dad always had one and loved them. Old school beliefs stick with what works. You may ask why not the Bushmaster 308, which the 223 has performed flawless to date and love? I have a chance to aquire t he M&P 308 as payment for a construction debt owed. I realize the DPMS oracle and Armalites are great rifles also, so I picked the Sig to compare against the S&W. Thank you much for your time.

    Understandable. I have HK's, S&W, LWRCI, and a Springfield M14 type with the S&W being the only DI.

    The advantages of the AR-10 derivatives is the modularity of accesories. In two of mine, I have Giselle triggers installed that were pretty much drop in. One is an SSA, the other is an adjustable high performance. For installing optics, the Picatinny rails make it very easy. For long range, you may want to consider one with offset so that you aren't maxed out on scope adjustments.

    Please forgive me, DI? Dislike perhaps.

    Direct impingement. This is where gas flows into the chamber to cycle the action. The original M16/AR15 were this way. The AR-10 was originally designed this way.

    This is vs. piston where a small amount of gas is fed into a tube with a piston and the piston cycles the action. Examples of these are M1 Garand, M14, SKS AK-47, and I believe FN-FAL.

    Pistons are heavier and there is a lot of traffic about piston vs DI and the advantages of each. Most believe the DI is more accurate while the piston is heavier. But the piston is cleaner since you don't have the gases flowing into the chamber and because many pistons have adjustments, you can control the amount of gas that is bled off to cycle the piston.

    I did notice the weight issue between the two rifles, The Sig being the heaviest of the two. But memories of long periods of cleaning my M16 during my service time do not hold well with me. I have not cleaned my ar15 yet because It was recommended to cycle a couple of hundred rounds threw it first and on my next outing I will do so, that reminds me to stock up one swabs. So I'm leaning to the Sig. And as far as recoil, is it me or does the DI seem to kick more than the gas type with this caliber round? From the you tube vids on the S&W the rifle seems to move more and sound louder than the Sig.

    Recoil is subjective. Stock configuration is a big factor in felt reqcoil. Also piston rifle being heavier would appear to feel to kick less.

    I've installed different stocks on each rifle to balance them for handling (i.e. a muzzle heavy rifle you really don't want a short stock on it)

    I don't have an apples to apples comparison.

    If you have a chance, you might want to handle some of the others to get a feel. SIG and LWRC feel about the same to me. I really like the HK. S&W's I feel feel is okay and I like the fact it is lighter, but I'd change the stock. All have their fans and detractors.
