Masterpiece Arms .22 Bullpup

Masterpiece Arms is displaying this offensively colored bullpup with no plaques or press releases partnered with the mock-up. Working with Charles St George they are working on a gun that is visually similar to his earlier design, the Bushmaster M17S, but chambered in .22 Magnum.

The firearm doesn’t have a release date and looking at the gun it was hard to tell if it was a mock-up or a gutted prototype. It is expected to have a 50 round capacity, though it is not currently clear if this will be in a rear-fed drum. It is too soon for them to answer the questions I tested on them, but I’m looking forward to Charles adding a matching .22 to his Micor .50 BMG design.

  • Some cool things about this:
    It was designed by the man who designed the M17 (an Australian gentleman)
    The man also designed the MPAR rifle for masterpiece arms (which is based on his Leader Dynamics T2)
    He relocated to the US after the strengthening of Aussie gun laws
    Nice as can be and very enthusiastic about this new rifle! I wish them well.

    Ken from K&M arms is making these. Only 500 will be made, at the price of $2,250:

    Ken is also making a new version of the Bushmaster M17s. With an aluminum lower receiver, and 3.5lb trigger pull at the price of $1,800:

      A 22 mag rifle for $2,250???? ROFL

    • Asdf

      Yep. I am on the wait list for one of the first pre-ordered 100.

      Sorry, too close in K-Mart Arms for me.

      A $2250 dollar fun toy is nice if you’re a drug dealer, a lawyer or a politician. but most gun nuts are just middle class working people so being one of those, I can’t take guns like this seriously or have any interest in it whatsoever.

    I thought this looked familiar as I said is that the Bushmaster M17s?. So when I read Charles Saint George was working MPA I almost did spit take.
    Considering what he’s been through Bushmaster really screwed this guy over.

    I wonder if they will be able to make a future short barrel version chambered in 5.7×28 like the MPA5.7. Giving it a “big brother” of sorts. Thus making Heckler and Koch and FN executives crap themselves.

  • Edward Franklin

    I’d had a feeling that Charles St. George had a hand in the MPAR-556, it was so close to the Leader T2 that his involvement seemed likely. This little guy on the other hand could be great fun. Masterpiece Arms may build some odd stuff but the quality is good and if this comes in around the price of their M10/11’s I ‘d be all over that!

  • JumpIf NotZero

    Lol, Nope.

  • wetcorps

    I quite like the streamlined look of it.

  • gunslinger

    holy hell is that thing ugly.
    well maybe for the next scyfy flick.

    and if the 2k price is true. wth!!!

    • maodeedee

      Where does it say that it’s MSRP is $2000.00???

  • Sulaco

    I know its only a .22 is there some type of legal issue with these vertical forgrips on rifles in the US?

    • gunslinger

      only if it’s on a pistol. a rifle (SBR or otherwise) is ok to have a forward VGrip w/o any issue.

      i think

    • Cymond

      Gunslinger is correct, there are no national laws restricting forward vertical grips on rifles, shotguns, SBRs, or SBSs (only pistols). However, for the sake of full disclosure, some places (like California) restrict what kinds of firearms can have a vertical grip. In California, you cannot put one on a semiautomatic centerfire with removable magazine.

    I like pistol caliber carbines. In 22 magnum this is something I;’d consider getting if it became available, unlike the carbine version of the Keltec PMR-30 whish is completely UN-available and un-obtainable as is their pistol except at scalper’s prices.

    So availability would be a factor once this gun go4es into production if the manufacturer could not keep up with the demand. And there’s one possible inherent flaw to this gun and that is the magazine.

    Rimfire cartridges are herd to get to feed reliably and whether or not the gun is reliable will depend more ion the quality of the magazine than the gun itself a 50 round capacity would be incredible IF it were 100 percent reliable.

    Another gun that’s appeared on the market recently, the Taurus 9mm carbine is something that I consider to be a failure in it’s current configuration because of it’s limited mag capacity,

    For what the Taurus carbines sell for I’d rather get a used Glock 19 or 17 and a Mech tech upper and be hble to use the Glock factory 33 round mags or the Korean 50 round drum which is very well made and has been 100 Per cent reliable in my experience.

    Its a lot of money for a gun that looks like a cheap piece of junk.

  • LeeC

    MPA .22 Mag Bullpup… cute… love the idea… even like the color, offer more choices… but “Dump The Lump!”… unless that unsightly thickness of the buttstock is needed for function, tailor that thing down! Extruded aluminum housing and minimal working parts should keep it an affordable toy. I could see this becoming “suppressor friendly”!

    Looks like the trigger group off of early 90’s semi-auto paintball guns like the F2 illustrator.
