    Hey every one i just got my stripped lower receiver from big cat and Im ready to start getting the internals. Im going to be putting a bushmaster 450 carbine upper on it and i don't want a run of the mill parts kit because i want the magpul trigger guard and i want the furniture to be dark earth.

    1. I wanted suggestions on the trigger assembly because I've looked at the bushmaster two stage trigger as well as the dpms and the stag arms ones and I cant find any definitive reason to get one over the other.

    2.with the 450 upper will i need to get a full butt stock or will a carbine stock be okay? (magpul makes a full rifle/ carbine stock hybrid.... any good?)

    3. does any one know if i can change the free floating hand guard on the 450 bushmaster to a quad rail?

    4. being that this is my first build, if anyone has any "do's and don'ts" to share that would be appreciated :)

    RRA has very nice 2 stages triggers as well.

    It doesn't matter what stock you put on it. I think you want to look at the buffer type more. For the stock just whatever you want on your gun.

    You can change the free floating hand guard out but you might need to put in a micro gas block depend on what you're looking to replace it with.

    Last question I leave to the more professional people here.

    How are you going to use the gun?

    Why did you pick the 450?

    I picked the 450 for boar hunting and for less mature reasons being...... its the biggest round before you get into the sniper style rounds and builds. when i was figuring out which build i wanted to do i reviewed the 450 bushmaster and was pleased with the following it is developing, the fact that Remington is picking it up and other companies are starting to use the caliber shows that it is going to have a pretty strong backing. After firing the 5.56 in the service i just wasn't happy with the stopping power of a small/fast round over a slower larger round especially when most engagements occur well within 500yrds.
    Basically i picked the 450 because i wanted a badass AR with big bore stopping power and decent range (200yrds+), I'm going to modify some 30 rd 5.56 to fit 10rds 450 to compensate for the low capacity.

    Why not build a .308? Good all around ballistics, easy to find ammo, more factory backing than you can shake a stick at.

    That's why we're here!

    If you are a reloader there are way more options for the 458. It uses the same .458 bullet as the .45-70 Government which has been around since 1873.

    This gun shoots as well as it looks!

    the socom also uses the big game bullets you find in the 458 winmag. i went 458 socom because of that and i dont have to modify the mags. the 450 uses .451 pistol bullets which arent generally great for hunting.

    I have the 450 and it kicks a$$. Also very, very accurate (1 hole at 100) Parts are parts with one exception, the trigger, get a goog one. I use JP. Also a slip on limb saver recoil pad will make it feel like a .223.

    done some more research

    well i did some more research and soul searching and i think I will stick with the 450 for this build. ballistics performance consistently edge .458 out (just barely) and the ammo is cheaper, which i find weird because the only companies making the loads are hornady and remington and the .458 is made by more companies but still more expensive. the only mod that the 10 rd magazine will need to properly feed the 450 is a single stack follower. the 458 is an awesome round but with the research i did and my own preferences i think it'll be the 450 bm for me.

    Another consideration is reloading. The 450 is a straight wall (pistol style) case and is much less prone to stretching like the bottleneck (458) type. So you'll get more life from your brass.

    It also uses 451.

    The socom quickly outstrips the 450 in hitting power when you go to larger bullets.

    remington 450

    @ Canebrake if I read your thread right . My remington R15 450 lower wont be compatable with a 223 upper cause of the buffer spring? Is this right. The 450 is a great bear gun and was thinking of getting a new upper in 223 for a cheaper plinker. Or am I just wasting my money?

    Not to derail, but has anyone tried a Wilson Combat 458 SOCOM upper? Wilson and Teppo Jutsu supposedly teamed up and Wilson is building 458 SOCOM uppers with Teppo Jutsu barrels and bolts.

    Last I checked on the 458ssocomforum Marty is out of country. I was under the impression that SBR was taking over the manufacturing duties as well as providing ammo? :confused:

    to the OP, my vote goes for an AR458 ;)
