    They have named it, it's now called the UltraMag 50. They are also taking orders for it now, $1,750.

    The upper weighs ten pounds. :scrutiny:

    That had better be one effective muzzle brake. :uhoh:

    The lower looks like a modified AR lower. Any more information on groups and what not??

    How much velocity would a .50 lose in a barrel that short?

    Tamara: Rather, it comes with a super slip 'n slide on which you fire it from. The recoil is transferred into rearward acceleration.

    The rifle comes with 50ft of slip 'n slide.

    According to Elmer Keith, the WWII era 48" bbl .50 MG would completely burn the powder. The 36" version would leave literally pounds of unburned powder in front of the gun after a firing session. That doesn't answer your question directly but does indicate that the longer bbl is necessary for complete combustion.

    Are there 'pounds' of powder in a 50BMG?

    There are in three or four ammo cans worth of ammunition.

    UltraMag 50

    Hello all - the recoil on the UltraMag 50 is not bad at all. The muzzle brake works great to lower recoil. The prototype has a 16.5 inch barrel but the production gun will have a 22". Than when things settle down we will offer even longer barrels. The lower on the prototype is a DPMS California lower. The UltraMag 50 will work with all AR/M16 lowers. Thanks for the kind words.

    man, i had an idea like that years ago, cept it was for 308 or 7.62x39. same mag idea (in the side of the receiver)

    gave it up because i figured an M14 (and especially an AK47) mag sticking out of the side of an AR15 would through the entire thing off balance and make it hard to hold level :)

    BigG,
    The barrel on my .50 is 31" long and using 215grs of powder in the stuff that I reload, there's never pounds of ammo left. In fact I would be suprised if you could find enough unburnt powder after I'm done to load half a .50 BMG case.

    Using 215grs of powder I get about 240 rounds loaded from an 8lb jug.

    I think he meant after firing many hundreds of rounds through the MG. Easy to do when uncle sam is footing the ammo :D

    The recoil seems to be suprisingly managable.

    UltraMags Recoil

    The UltraMag 50 prototype has a 16.5 inch barrel and the whole rifle weighs in at around 15 lbs. Being so light you would think it would really knock you around but it does not. Since the barrel is shorter the burning powder does not have time to finish burning in the barrel thus it doesnt create as much recoil . It also helps having a very good muzzle brake too. Even with the shorter barrel at 200 yards we have shot 1 1/2" groups.

    Make it a 36" Walther BBL & I might just get one. Dunno when I may have to stop a calvary charge. ;)

    Just curious, how do the barrel and receiver meet? Through a threaded interface or held together by a weld? Say a barrel is burned out one day, is it a relatively easy task to turn a new barrel and install it or is it a bit more involved? Not just in the event that a barrel should be worn out but in the event that a change in barrel length is desired, such as the introductory barrel one day being replaced by a longer length barrel.

    I ask because that's one of the main concerns of mine when debating whether I should go for one of these AR15 uppers or spend another 800-1k dollars and just go right for an AR50 which may prove to be more easy to work with at some point down the road if a rebuild or maintenence is needed.


    Is it a freefloated design? And I'm curious how the bolt and receiver lugs interface, steel on steel similar to that of a Reminton 700 or other push feed two lug bolt? Any close up pictures of the action or showing detail of various parts of the action?



    That thing has got me pretty darned interested, nicest looking of all the AR15 uppers I have seen for 50BMG.

    UltraMag 50 Barrel attachment

    The UltraMag's barrel is screwed in making barrel replacement relatively easy.
    The barrel is not free floating though - the handguard is held in place by threads midway down the barrel. This feature makes it easier to increase the barrel length and at the same time lengthen the handguard. We will be offering a longer barrel later as thing settle in.
    The bolt is a two lug design - like to post some pics but my wife is out of town with the digital camera :-(

    Those 2-1/2" groups @ 200 yards... Is there a large ammount of match components for the 50BMG? HPBT match grade bullets?

    How much do those go for anyway? I'm looking at reloading, and my buddy gets a boxes of (i think) 50 7.62 HPBT for like ~$20. How much do 50BMG bullets go for?
