    Im looking heavily at getting a bcm 16" midlength lightweight a4 type rifle. Ive got an rra i love due to its accuracy. Both bcm and rra both offer the same configured rifle but the price of the bcm is a little less than the rra.

    If i part out the rra it comes a little closer but i would be using mostly bcm parts do it.

    One gun is made in illinoise the other is made in wisconsin. Both companies are within driving distance of me in case i need to do some yelling in person. Heh. My ffl guy is like within 10 miles of bcm.

    Im looking for opinions on one vs the other for gun that will be run hard. Please no arguing over whose opinion is right or wrong.

    This will be my ohsht gun so failure is not an option weight is a key factor. Im not interested in piston systems.

    The RRA with a Wilde Chamber or .223 chamber and non-chrome lined barrel will always be more accurate than a BCM. BCMs are total mil-spec (even the midlength ones meet all other military and Colt TDP requirments). A 5.56 chamber and chrome lining aid abusive environments, not accuracy. So you need to choose....

    BCM for the war-dog work horse, ride her hard and put her away wet...she will always bang when you need her to.
    RRA for the tuned customized carbine, that needs a soft touch and care, but will poke someones eye out at 500 yards.



    EDIT- I just re-read your post. I think you know my answer...lol You can get a RRA to be spot on with a BCM. I would avoid the midlength if you run cheap or underpowered ammo. Midlength gas system can be picky and not cycle with low powered 55gr.

    Jon, I'm not really familiar with RRA, as you know. I do have a BCM upper, with the FA BCG, a 16" carbine system, and it eats anything I throw in it, and is very accurate.
    Just my opinion of BCM, but in a SHTF scenario as you are describing? I wouldn't hesitate to grab it up and go. And no, I'm not babying it. It just gets basic maintenance because, while it's primary role is plinker at this time, it was built to be a SHTF firearm, and it fits the bill quite admirably.

    Hey I love my 16" Midl-length RRA too, but if you can get the BCM to work for you financially I don't think you'll ever regret getting it. They make some fine rifles and have an excellent reputation. :cool:

    I got my BCM 16" middy lightweight and BCM fa BCG roughly 2 months ago. I have since ran 1000 rounds of mostly cheap steel case ammo (I have mixed some brass in there to make sure it runs). I have not had even 1 issue with it yet. I cleaned and oiled brand new and after 700 rounds I put a little oil on the BCG. I will now get back to regular cleaning. I wanted to make sure it would take some abuse.
    I have no complaints with accuracy either. I mostly shoot up close and fast but I did spend a little time at 200 and 300 yards which I was overt impressed with.
    I have no experience with RRA but I don't see how you can go wrong with BCM for a shtf gun. Not to mention you would be supporting our local economy by going with the BCM.

    I vote bcm for you intended use. If you have a standard carbine buffer keep it handy if needed for the lower power ammo, but honestly you probably won't need it. And its cheaper. Sounds like win win 2 me.

    I also would go with BCM for this application. RRA is known for accuracy but when talking SHTF, BCM is geared for this. On top of that BCM's price is the same or less and it's local, well that's the end of the discussion to me. In fact I just ordered a BCM 16" LW midlength upper to build a similar rifle.

    I disagree with the comment above to avoid a midlength as it is picky with light powered ammo. My ArmaLite and Daniel Defense 16" midlengths have no problems cycling cheap Tula and Wolf. Even using an H buffer. Nothing wrong with carbine gas length but I'd rather have the smoothness of midlength. I expect the new BCM middy to function just as well as my other two.

    My BCM midlength LW has had 1500 rounds sent down range with 0 malfunctions. About 600 of those rounds were various russian steel case brands. I highly recommend BCM for SHTF apps

    BCM used to have a warning about using lower powered or cheap ammo with their Midlength. They have since removed the warning without stating if they increased the gas port size (and risk many people saying the rifle is now overgassed) or if they will simply tell the few who complain, "its the ammo, not the rifle."

    If you google search you can find old threads on it on AR15.com.

    I can see issues with low powered ammo in a 14.5" middy but wouldn't worry about a BCM 16".

    thanks for all the input im going with the bcm. price is the same for both.

    however they have three different charging handles bcmgunfighter large medium small. i know nothing about these and may just not get one and use a standard charging handle.

    The mod 3 is the big one, really useful if you have a scope mounted far back or if you wear gloves when shooting.

    The mod 4 is medium size one, its very nice.

    The mod 5 is small. Never tried it myself.

    I wear gloves when shooting, and I prefer my mod 3s over my mod 4.


    I really do recommend them, they are alot easier and smoother to operate than a standard charging handle.

    I have the mod 4 and it works much better for me than a standard charging handle. I have quite large hands and it works good for me although I have not shot with gloves yet. I wouldn't mind trying out the mod 3. I would highly recommend 1 or the other over the standard.

    I have the Mod 4 and my new BCM upper is coming with another Mod 4. I still have a standard CH in my ArmaLite. The cost is only $25 more than a standard CH and I think you'll be pleased with the improvement. It's not something you need but you will like how it functions and the extra strength. Pretty cheap upgrade and somehow a BCM upper isn't complete without the Gunfighter too! :D

    I have the Mod 3, operational side of things, it's great but if you plan on using a sling it has a tendency to be a little "pokey" which is my only complaint. Check out Primary Arms, they've been having sales on em lately for 35.99.

    I use mine with 2 fingers most of the time. It is very smooth. I especially like that you can grab it from just the latch side to pull back if needed. I think the mod 4 would be a great fit. Not overly huge but big enough to grab in a hurry if needed.

    I have the RRA elite operator2. 16 inch barrel mid-length gas system. I've shot lots of cheap .223 both steel case and brass case. Never had a problem with it. I have thought of changing out the charging handle but I figure if it ain't broke... I have not been able to get my hands on a BCM to try yet, id sure like to, just to see what they are like.
    I do really like my RRA and feel that I could depend on it in any situation.

    Honestly there's not a huge advantage when using the CH the old way. The Gunfighter excels when you're in a hurry and charge with the left hand like Tikki described.
