My “Stoooopid” AR Build - Ideas

Uncle FesterUncle Fester Senior MemberPosts: 1,370 Senior Member
Having completed my simple carbine build, I decided that I enjoyed building it myself. I am in the process of gathering parts for my monster blaster.

Purpose: I am celebrating the end of my exile to a the People’s Republic with a build “just because I can.”  While I could conceivably use it as a hog killer, the main purpose is to go big, loud and obnoxious.

1) I am looking at doing a .450 Bushmaster or .458 Socom.  While I don’t reload now, I could conceivably try it in 2020 or 2021.  In terms of cost per round (reloading or otherwise), it is my understanding that the 450 is going to be cheaper.  Is that correct?  Since I don’t plan to shoot this thing that often, which one is the most stoopid?  (Remember- Goal -> maximum fun) 

2)  This thing is not going to get shot thousands of rounds per year.  Do I need a “good” barrel or would something inexpensive from a place like Bear Creek Arsenal be OK?  So far, I have found really expensive barrels or really cheap ones.  Generally, I like to buy “Honda” quality not Kia or Mercedes.

Thanks.

    I haven't researched it, but my gut tells me that.450 Bushmaster is the round that will cost less because it is chambered in more rifles. Barrels? Expensive barrels tend to be more accurate than cheaper ones. Since I doubt you are looking for match accuracy, I do not feel a Kia barrel will make any noticeable difference for you over the Mercedes.

    These kids in my hood with powerful car speakers that make percussion redundancy that rattles the windows are as loud and obnoxious as one can get.

    But this could be a close second.

    If you want obnoxious, how about the .22 Eargesplitten Loudenboomer? At least the bullets would be cheap!

    Every time I think about building a big bore AR I decide against it because I don't think I would shoot it much and I don't have a hunting purpose for one. If I was to throw one together I'd look at .375 SOCOM.

    Have you considered the 50 Beowolf? And to be extra obnoxious, don't forget to have the barrel cryo-treated.

    I see .450 BM being around longer than. 458 SOCOM.  When it comes to reloading I see the. 450BM also being the more economical of the two as well.

    The .50 may have been around longer, but I really only see one store shelf option for ammunition.  At least with the .450 BM you have several manufactures offering ammunition that can be found on store shelves.  I can only recall ever once seeing .458 SOCOM factory ammunition on a store shelf.

    If you are ordering online then you do have more options of course.  I am just going by what I see on store shelves when I am out and about.

    If I had to pick a factory offering of the three then I would go with the .450 BM.  

    Having been at the range while someone was shooting a .450 BM with a muzzle brake on it, obnoxious is not even close to describing it.  I had to stop early and go home due to the headache I was getting from it.

    I have no opinion as to which big-ash bore you should choose; I've no experience with any of them.  I will say this: I would not worry about barrel longevity with those calibers as the throat erosion will be minimal with these big boomers.  You might want to get a barrel that is chrome lined to ensure maximum longevity.  As was stated by Jermanator, the more expensive barrels will be more precise and I don't think that's what you're going for here.

    I can't help you because I am an old fart that is only obnoxious in his daydreams. I guess it is my "gentlemen are not obnoxious" upbringing, by Oklahoma share-croppers. I've never even 'dumped' a 20 round mag. So, take this opinion with a grain of salt.

    The cheapest Palmetto .308 AR components could be assembled into something that would probably 'blow your dress up' enough to make you smile, with the added bonus being that you would actually enjoy shooting it, in excess of the 100 rounds you will probably fire through the boomer.

    Sorry to be so uncool, but I am in my grandpa mode, at the moment.

    No worries.  I have always had a screw loose and wanted to do some strange things like this.

    If I win the lottery, I plan to get one of those giant civil war siege mortars and have it mounted in my front yard.  😇

    If I were going to build one, I'd do it in .338 Lapua Magnum.  That would make for a mighty useful AR...

    Especially when you claim to have "stolen" my load ;)

    I still say you can't "steal" something that was freely given to you :D:D:D:smile:

    That’s what made it so easy, I didn’t have to develop the load! ;-)

    I ended up going with a 450 Bushmaster barrel for the project.  Unfortunately, I probably will put the project on hold until Winter as I bought a Lab puppy who will need training.
