    First I would like to make this abundantly clear. I will not tolerate any bad mouthing of my AR. Please save it for another treated. This is a question and answer thread plan and simple. My AR has been Very good to me. and I have put thousands of rounds thru it with out a hiccup. I have a Bushmaster C15, Now that you know what I have on to the question. It has a 16in Barrel on it, I am aware a normal AR barrel will not fit. I am mainly a long rang shooter, Therefor I want a longer barrel. Does any body know who if any body other then bushmaster makes a longer barrel? The longest BM makes is 20in. I would like to go a smig longer then that. certainly with the number of these now in private hands some one has to step up to the plate. By the way the Timmney trigger works wonders :) And before anybody wonders mine is the latest generation all the past problems have been fixed the thing is a tack driver and I adore it.

    How far do you consider long distance ? Im was not aware that any other barrel wont fit the C15 upper . You looking for a 22-24" barrel ? Any particular material like Stainless ?

    I don't know if they have anything longer than 20", but check with Green Mountain, White Oak, Rock, E R Shaw and see if they have something you like.

    Any "American" AR15 barrel will work on the Bushy C15. Unsure about the Mossberg MMR series Sports Rifles as I've not handled one to see if their barrel is a true AR barrel.

    A longer heavier barrel on Carbon-15 receivers probably isn't a good idea. Call BM and see what they think.

    I'd leave the C-15 as the lightweight it was intended to be and start looking at a second AR with 7075-T6 receivers, you know you want it!

    Was that badmouthing? :D

    Just my opinion,but don't most people buy a Carbon AR for the weight savings? Why would you want to make a Carbon gun heavier?
    Being a 223/5.56, shooting 600 yards is about as far as most good shooters will shoot the caliber,and a 16 inch barrel will do that just fine,but a few FPS slower.

    I only ask because some people call 300 yards long distance and other peoples long distance is 800 yards .

    i also don't think most would think of lightweight AR's as precision long range rifles either.

    The only caution I have would be regarding a heavy profile/long barrel and the carbon upper at the barrel nut joint causing some extra leverage stress at a thin spot of the receiver. Most polymer ARs that I see are configured as carbines.

    This is not intended as a criticism, but an observation. Most AR buyers choose polymer for a couple if reasons. One is cost and the other is weight. If choosing for weight, a carbine seems the logical choice. If choosing for cost, long range precision accuracy is usually not the primary requirement. Also balance/handling will be very front heavy with a heavy barreled/polymer receiver combination. This may not be an issue if bench shooting will be the primary role. If doing any off hand shooting, it may be an issue. For three position high powered rifle matches, balance can become a big issue as using muscle to overcome imbalance may cause additional muscle fatigue and tremors that can affect accuracy and scores negatively.

    Not saying it can't be done, but just that from a viewpoint if form following function, it seems kind of counterintuitive to build a "heavy polymer" platform.

    If you do assemble this project, I do hope you will share your results. It would be interesting to see how it works out.

    The 223/556 is a 600 yard cartridge and that's it. 20 inch barrel is as long as it gets before length adds no velocity worth mentining.

    Polymer in rifles at stress points is a negative factor in predictable poi. The polymer flexes too much which is why you will never see one with a long thick barrel. The leverage on the barrel nut and receiver is a huge factor, meaning you put pressure on the barrel your get a lot of flex. The more polymer flexes the more it weakens as polymer is strong only along the length. As it flexes the weak bonds holding the fibers to each other widen and cracks form. This leads to stress fractures.

    Sounds like you like your rifle. Do it a favor don't put a heavier longer barrel on it.

    LOL.

    Right. Where we shoot, anything more than 500 FEET would be considered long range. I'd have not a clue as to where to go to find 800 yards. +1 on another AR. Or a bolt gun.

    Totally understand and thats why I asked the question , I used to be in the same situation on limited range of 120 yards until my buddy let me in his place . He has 900 yards with back stops . I dont shoot that far and 500 is about max for myself . Hear me say this 500 seems like a LOOOOONNNNNGGGGG ways away I cant imagine shooting out to 1000 like some of these other shooters do .

    ATV or a golf cart to check targets at 500-1000 yards!:D

    if you walked it, you would be too tired to pull the trigger again once you made it back!:(

    One of our Early Guests on the Podcast was Jay Jacobs of Franklin Armory. His feeling is after 20" no value comes from any additional length in the 223/5.56 chambering. In 308/7.62 it's a different story, as I have 2 Springfields, a 20" A1 and a 24" E2, and the longer barrels in 7.62,...well,.
    Edit: as for the Bushmaster, it's what you like, so who am I to say what you Iike SUKKS or not? I prefer my mini14, but I have had mine for 22+ years. My AR is only a yr. old, and in a Pistol caliber. If I were getting one in 223/5.56 it might be an 11"-12" one, Because I'd rather have one....and see what it does, since I already know what a 16" does...in terms of wound channels

    Much to my surprise there hasnt been a problem. All the other sight I have asked questions in I have gotten nothing but grief for daring to own a C15. I to have been learning a lot. At this point I am so glad I joined the site. I do appoligse for comeing off like a hard ***, but I am a little gun shy.

    Most people would not but I am not most people LOL. I want to do to see if it can be done.

    After reading that I am having second thought about changing barrels at all. If I do, 20' is a long as I will go. Most of the shooting I do is bench AKA ground LOL Helps to know a fellow prepper who is also a farmer withe a lot of land, who also loves to shoot. Most of the the 800yrd shots I take now are with my mosin nagant. Arch angel makes a great stock for it and Gander mountain too care of the new bolt handle that I bought on ebay and mounted a fantastic long rang scope, My 303 British makes it out to 600 yards The fault of the only shells I can find for a weapon that old. They say the nagant will make it to a thousand yards and I have seen it on youtube, but I have no place to test that :confused:

    You're referring to my signature line. It was in response to a specific issue I thought we were having here a while ago, with one individual in particular. Seems to be better now. Of course, now there are other issues.

    Took the words out of my mouth. Ive loved the M16 for what it was designed to do, reach out and touch someone longtime without breaking the back of the person humping it and the ammo. 300 meters is still impressive for a short weapon but other than a SHTF scenario, I would have to hide it and become a felon to own one in my lovely state of NY.

    Hope you figure out whats going on with it!
