I'm pretty sure that they have done enough research to know whether or not fluting would or would not negatively effect accuracy. I have had both fluted and non fluted barrels and both will shoot much better then most of the shooters who own them. I still maintain that other then weight and cooling, flutting is a non issue.
And we can agree to disagree, which I am fine with on this issue as it is HIGHLY subjective to who is doing the talking.
Sabre is a high end AR manufacturer. No argument there.
They are NOT
a high end BARREL manufacturer. No one is ordering a "Sabre Barrel" for their AR to take to Nationals or to a 3-Gun. Why??
Because Sabre is selling you a barrel that THEY believe is one of the best.
Sabre is a BRAND
built on a very quality assembled AR from the ground up, which happens to include a barrel that they have decided is the best FOR THEIR PRODUCT.
I have no doubt that your fluted 18" barrel (I believe from reading your posts) shoots as well as anyone here can shoot it. I believe that you did your research and that you feel that barrel is absolutely the best for your needs. Absolutely no argument from me there. There is NOTHING wrong with a SABRE barrel.
However, let's stick to the facts here for a moment.
Sabre uses Button Rifling, according to many sources. There is nothing wrong with that.
But Single-Point, Cut Rifling is the gold standard by which others are judged.
Now, 5R is making a play for the top competitor, and as I have a rifle in the shop getting a 5R barrel I will let the forum know the results of that experiment.
But right now, Single Point, Cut Rifling is the end all beat all.
Now, as to the question at hand: Does Fluting Make a Difference In Accuracy.
This is HIGHLY subjective as I have stated numerous times because there are "experts" on both sides of the fence.
I have personally had a bull barrel rifle that I had "properly fluted" by my gunsmith of whom I also shop rat for and respect a great deal. The weapon dropped a ton of weight, but the even though it was the same ammo ( Federal Gold Medal Match of which the chamber was cut for using a brand new reamer ) and the same shooter ( me ), I noticed a difference in the grouping ability of the rifle. The barrel was a Krieger and the caliber was in a .308
At the end of the day is the average shooter going to notice a level of accuracy changed by fluting on an AR type of weapon? No, not in the least.
But everything being 100% equal, I have personally seen a difference with proper fluting affecting accuracy on a very, VERY good rifle.
