I know there have already been threads regarding stainless vs chrome however mostly it had to do with incredibly expensive stainless steel barrels vs the typical chrome lined barrels.

BCM offers stainless SS410 and a Chrome BFH upper with only a difference of 10 dollars.

As far as I understand, the SS weighs a bit more. This, is solid truth as far as I know.

Just how much more maintenance does this SS barrel require?
Can it take crap ammo just well as the chrome? (I will be using both quality and low quality ammo at times)
Just how much less will a SS barrel last in comparison, is it even significant? I have a feeling I'll never wear mine out, do you know anyone who did?
I know there are members here that have run their SS barrels through hell with no problems so is there any real reason to NOT take advantage of the accuracy gains besides weight?

Running a mix of quality and low quality ammo kind of negates the accuracy gains of SS over CMV. What kind of shooting are you going to be doing? I could be wrong but it appears to me like you're more after a general purpose type barrel, in which case, a CMV barrel would be more than sufficient.

I have both of these BCM barrels and while I have shot steel Russian ammo in both, I have lately shot nothing but brass in the SS barrel, including commercial match. I am not a cleaning fanatic and am a big fan of Boresnakes. The SS410 had a short break-in period that included using a BoreSnake after each of the first 10 shots and after three or four five shot groups. The BFH had no "break-in" of any kind.
Both barrels are 16" and are close in accuracy with a slight edge to the SS. This is not NOT based on documented shooting and I have no pics of targets so hold any "5000 rounds through each are needed for a proper evaluation" comments. This is just a PERSONAL observation based upon memory (such as it is). :D

This might help you:


Sure would, and do. I'm somewhat of an "accuracy nut," and give minor advantages in precision between platforms a lot more consideration than I think most people do. A 0.5 MOA difference in accuracy can make or break my relationship with a rifle.

Because of this, and also because of the fact that my particular profession requires very precise shooting sticks, I have moved almost exclusively to SS barrels for both work and personal rifles.

For what it's worth, I wouldn't worry too much about the durability of a Stainless barrel for the vast majority of applications. Here's how I'll qualify that statement:

I've personally put somewhere around 12K rounds of MK262 through an issued MK12 Mod 1 both in training and overseas in the last few years. All rounds were shot suppressed and some were F/A as it was on an M16A1 lower. F/A fire is not really in the job description for a MK12 but given the capability I chose to become intimately familiar with operating the rifle in this way. The firing schedule over the course of those 12k rounds was varied. Sometimes I would only need to shoot 10 or 15 rounds in one engagement over the course of a few hours...on really bad days it would see 6 or 7 magazines in 10 minutes.

The barrel was new when I got it so I had a blank slate to work with, which is always a good feeling with an issued gun. Anyway, I established an accuracy baseline in the beginning and found it to be a solid 3/4 MOA gun with MK262. Fast-forward 20 months and 12 thousand rounds (I'm anal about logging round counts with my rifles). I have a ritual of going out to the range every two weeks when possible to confirm zero and make sure accuracy is where it needs to be. Even at the end of my time with that rifle it was still producing the same boringly accurate results after 12k rounds.

Corrosion wise, I had no issues. The rifle saw austere conditions, summer time humidity, rain, winter sleet and snow...but I always made sure it was oiled and clean. If you take care of a stainless barrel it will take care of you. Neglect it and it and you will have problems. Even relatively cut off from the supply chain in the Afghan mountains, myself and everybody else in the section with stainless barrels was able to keep them in A+ condition. Non-issue unless you plan on not being around a decent CLP for months at a time. That's not real life. While important for somebody's end of the world fantasy, not being able to get CLP on and in the barrel is not a real world consideration.

On the personally owned side of things (the following is taken from a previous post of mine but much of it applies here):

What I've noticed about my BCM SS410 barrel is that groups do in fact open up when the barrel gets extremely hot but POI does not shift. The groups just expand but stay centered. Even when the barrel gets to this point (extremely hot), my groups won't open up past 1.5 MOA...better than many chrome lined barrels when cool, and far better than most chrome lined barrels when hot. In the last few months I've put 5K rounds through my SS410 and have noticed no degradation in accuracy. It still prints 1/2 to 3/4 MOA 10 shot groups, only opening up beyond that when really really pushed heat wise.

------------------------------------------------------------------------

Now, after all that, here's what I think people need to look at when selecting a stainless vs chrome lined barrel.

- Are you in a position to be able to feed it exclusively match grade ammunition? There's no point in going stainless if you're shooting M855. The best barrel in the world won't make inaccurate ammunition shoot straight. If you can't afford / can't use match ammunition for whatever reason...go chrome.

- If the answer to above is YES, then you are either pretty well off financially or your unit or organization is in a place to provide it. In either of these cases, the monetary cost / practical difficulty of a replacement barrel will be absolutely trivial in comparison to the cost and availability of ammunition. In other words, if you can afford 10-15k rounds of match ammunition, you can afford a new barrel. If your unit / organization can get that much match ammunition, it can get you a new barrel. In either case, barrel life is a non issue.

- Corrosion problems and sudden catastrophic failures from high volumes of fire are in my experience not relevant or warranted fears. I'm not trying to tell war stories here but I've asked a lot out of stainless barrels in some engagements as large and frenzied as you can imagine in the valleys and mountains of eastern Afghanistan. I don't forsee many other stainless "duty" barrels being faced with 125 red bearded nutjobs advancing down the mountain toward them. Having been in such situations with a stainless barrel I have to question the veracity of anybody who claims that SS barrels are not durable enough for "combat." Gotta wonder what they're basing that off of. Rest assured that a good stainless barrel is more than durable enough for combat conditions. Deliberately doing 10 mag dumps in a row on the range for Youtube is another story. Also not real life.

So, my position is that if you can take an honest look at yourself and determine that A) you can shoot to the potential of a match type barrel and B) you can afford to feed it a high quality diet and C) You don't mind the extra weight from the SS and beefier contour and D) you will not neglect to maintain your equipment...that you in fact SHOULD choose a stainless barrel for the edge in accuracy.

If the answer to any of these or the above questions is NO...go chrome.

Sorry for being so long winded.
