Rainier Arms CHF barrels on sale

That's awesome cause everyone knows that Cold Hammer forged barrels will last longer and are more accurate than cut barrels .
Dead serious . It's why mausers are so absurdly accurate . There is empirical data to back up the round count benefit also .
AFAIK CLHF is more viable for high ROF and low rate of cleaning compared to just SS or nitride. Both can be equally as accurate, but usually, SS is easier to make accurately.
yep and these are AR barrels, can only get so accurate with all that is involved, but accurate enough for the Mil Std of 1 MOA do you might as well get the life long lasting CLHE
Actually not as good as CHF . Stainless while harder and when rifling provides sharper rifling it work hardens . CHF compresses and aligns the material grain therefore thin rifling edges are denser than stainless . Also stainless is more rigid than the chromoly steels used in barrels . This results in rifled edge fractures toward the end of barrel life as opposed to wear .
You had to be logged in for the code to work. Just checked with Rainier and they changed it to show for non logged in people. You should be g2g now
True Alpha. However, chrome lining is harder to get as accurate a bore and as smooth a surface for the same effort/cost. Chrome is (again, AFAIK) more corrosion resistant than SS or nitride and in that way offers a benefit when cleaning is concerned.
What do you mean by strong? It has a better sheer strength, it has better tensile strength. Stainless stretches easier, so your bullet is not even touching the grooves after the first few inches because the barrel stretches and balloons from the pressure.
Every barrel has its purpose. I have many of both types. Why have more ammo than you have barrel life of?
Buy more barrels.
Carbon steel is composed of iron and 0.12 - 2.00 percent carbon. The broader definition includes alloy steels, which can also contain up to 10.5 percent alloy content. Even within the confines of under two percentage points of carbon, there is a huge variance in physical characteristics—especially hardness. Not all carbon steels are created equally.
Stainless steels are generally tougher than high carbon. Not necessarily harder, though SS has a greater ductility and a greater capacity for work hardening than carbon steels. Stainless steel does not rust, chip or stain easily as carbon steels do. Technically speaking, stainless steel can still rust but it resists it a lot better than high carbon. Whereas carbon steel typically exhibits linear elastic behaviour up to the yield stress, and a plateau before strain hardening— stainless steel has a more rounded response with no well-defined yield stress. Typically, that is. Not all SS are created equally, either.
So in general you agree that the ss barrels balloon under pressure and reg bullets are not getting similar spin to stabilize uniformly as they would in a non cut chrome lined CHF barrel that does not balloon under pressure. Further, how can you get ratable spin drift from a barrel that balloons under pressure at different pressures.
Code still doesnt work, logged in or not. Still a damn good deal. Wish they had 16" in stock. 14.5 isnt worth the trouble to pin and isnt short enough to make sense for a pistol brace imo.
I will email Rainier again. They just emailed me and said it was working.....
I assume no responsibility, ability, or overt concern with the interest of applying what's true in metallurgy to what's universally "best" respective to barrel making. I am certain what I have said is true in any case. I can make carbon steel in my basement that will shatter on the floor, I can make SS that's hand malleable. There is a spectrum, what you choose and how you work it for the application is as much of a concern as the metal with which you have started.
Hey Guys,
Unfortunately the coupon code cannot be stacked with sale items. I failed to update @padom about the change. My apologies. If you have any issues with ordering off of rainierarms.com please PM or email me. [email protected]

Ok guys. Mike just sent me a coupon for free shipping on your orders. Will not stack with the PADOM10 coupon but you can use it on those sale items to help you out.

Hi, all the 16" mid length gas barrels are currently shown out of stock. Will there be any more under this sale?
Thanks either way!
Thanks either way!
I am often surprised at how many people think stainLESS steel is stainPROOF steel. Stainless can rust, it just resists rust better than carbon steels because of some of the trace elements that are alloyed into the steel, hence stainLESS, as opposed to stainPROOF.
Either stainless, or carbon steel can be made into good barrels. The accuracy of the barrel will have more to do with the skill of the company that makes the barrel, than it does from whether the barrel was made from stainless, or carbon steel.
Unless someone is going to be using the rifle in extreme cold (as in Arctic) conditions, either steel will work for the barrel. I agree that chrome lining assists longevity in a barrel.

As to the chrome line vanadium steels vs stainless, I can't be the only one who has seen a pile of FN chrome lined bolt guns shoot well sub moa, as well as a couple of SCAR 17/(Mk 20's?)? Also several Daniel defense barrels, of which I own one of that stay sub moa with match ammo. FN, Rainier, DD, Criterion, and possibly others as far as I can see all make solid barrels these days in chrome lined varieties. Criterion doesn't claim an advantage of one over the other. The AMU is using SBN stainless, but they are having their own match shooters use chrome lined barrels the last time I looked into it. For most AR users I don't think there is an advantage other than finding the prominently available profiles to suit their usage needs.
These seem to be good barrels on paper and an outstanding bargain. The 18" pinned out with a .093" gas port so they should make smooth shooters. Wish I was able to snag a 20"
Not a barrel expert but if I can find a CL option, that is what I pick. Once you go CL, you dont go back.
Wish Criterion or someone would offer CL AI barrels...

I agree with SS vs carbon is largely superficial. Looking at profiles, twist, and gas lengths are usually what it comes down to for me— also if the maker has a good reputation. I choose SS when I can simply because I don't do (rifle) mag dumps or put anything away dirty, and they tend to be more accurate for the dollar. I'd probably prefer chrome lined carbon for a dedicated weapon or any PDW style builds, though. A deal on CHF is as good as a deal on SS imo, I'd say 9/10 end users will never encounter the ways in which they are different on an AR15.
Eastern standard time. When I select standard profile the only option shown is 18". For the midweight profile it shows 16" as out of stock, as it did when I posted. The add to cart button is greyed out. If it was not the order would have went in then. Evidently, missed it by that much, as they say.
Me too . I went back and looked and did not see in stock . But I came across the fluted Glo k barrels again and it reminded me bow funny that is . I guess they figure if your stupid enough to buy a Glock your dumb enough to buy a fluted barrel .
And hey how would you like to buy the Glock Bridge . Ya know the one in NY NY that goes into brooklyn . ????
The checkout buttons are in AR parts . I got one for $7.50 plus shipping . I think I saw some blems for five bucks .
