Huh. They CAN make something uglier than a Glock. I stand corrected.

  +1000000000!

  I’m part Austrian and I think Glocks are fugly too. But this thing takes the cake.

Kinda looks like something I’d make in my workshop out of scrounged scrap metal and hardware. Apparently one does not need a 3D printer to make a firearm at home.

  Can’t you make a MAC from a flat like an AK? Pretty sure you can.

That’s just a pistol with a stock… Looks ugly too ugly
Michael B. October 10, 2012 At 15:28

If Transformers defecated, I imagine some of their **** might look like this.
MotoJB October 10, 2012 At 15:34

They should call it…wait…wait for it…

…”The MACenstein”!

Yuk, yuk.

I’m willing to buy guns that are not beauty pageant winners provided they are real performers with delivering bullets. I associate the words “master piece” with an aesthetically appealing work of beauty. This industrial-art student project gizmo featured must be a butt-ugly design on purpose. Does the maker imagine that gun buyers equate cold industrial design with good performance? This thing hurts my eyes so much that I’m leaving this site to go for a bike ride.

If it weren’t for the prohibitive cost of 5.7mm ammo, I think many more manufacturers would venture into the 5.7 market.

The 5.7 costs at least 50 cents a round. That’s not excessive for defensive-grade ammo, but it’s only a little cheaper than bulk .308. It’s a shame that there are no steel-cased Wolf or aluminum-cased CCI Blazer 5.7s to practice with.

  The problem isn’t the manufacturers. It’s FN. They are exceedingly stingy with the load data, hence why there’s no handload information widely available.

The carbine version looks a bit better…both are still really ugly. I dont really get what look they were going for with this. Mix-matched project gun done wrong comes to mind when I look at it, but thats just me…Why have gloss black buttstock, flat black pistol, gloss black rails, and stainless steel barrel?
- Mark N. October 10, 2012 At 17:32
  
  That’s a suppressor, not a stainless barrel. If that helps.
JR Lorencz October 10, 2012 At 16:04

I think that looks…Vuaggghhhharrffff!!!!!!!!

Wow…sorry. Gotta clean up here.
OHgunner October 10, 2012 At 16:13

I think saying that that series of firearm (the pistol and now the SBR) have the ergonomics of a brick would be insulting to a brick. Do people actually buy these things? This post should have been a “From the depths of uselessness…” Post, but then again I see the large sidebar add for MPA…

  D’oh. Phone Autocorrected the correct “ad” to the incorrect “add”. Aaaannnd the edit button disappeared. Sorry grammar Nazi’s.
- Jim July 7, 2013 At 17:48
  
  Yeah, people do buy um, and they never jam, spot on… sheds 4 calibers available
Ralph October 10, 2012 At 16:15

“MPA570SST-SBR Short Barrel Rifle” is just a tad unwieldy. MasterPiece should just call it the “Upchuck” and leave it at that.

I’d like to order one in pink for my ex-GF.
ADN October 10, 2012 At 16:26

Boy, HK’s civvy version of the MP7 sure looks different. Wait, what…?
Jim October 10, 2012 At 16:32

You’d find less sharp edges on a chainsaw.
bo October 10, 2012 At 16:35

Where’s the neon green zombie killing version?
jwm October 10, 2012 At 16:35

Ugly can be functional. It’ll always be ugly, but it can be functional. But what’s this fascination with the 5.7 round? Make it in something more common and cheaper like 9 or 40 or 45. I can buy any of these rounds cheaper at wally world for practice.
- Spelunker5 December 13, 2012 At 23:08
  
  I think they make pistols and rifles of similar style in those common calibers: https://www.masterpiecearms.com/products.php?cat=30
  
  Looks like a MAC with tac rail, but hey if you’re going to buy a MAC why not?
Danny McBee October 10, 2012 At 16:40

Looks kinda cool, like something I made out of a muffler at a junk yard.
KnowWhatIamTalkingAbout October 10, 2012 At 17:21

And the point of this contraption is . . .what?
- Mark N. October 11, 2012 At 21:10
  
  tacticool. Useless otherwise.
Mark N. October 10, 2012 At 17:37

A 10″ barrel and they add a scope mount? What on earth for? It’s not like you need one to shoot 15 yards.
"lee n. field" October 10, 2012 At 21:58

Hope it shoots better than it looks.
- bontai Joe October 16, 2012 At 14:37
  
  I hoep so too because if it looks better than it shoots, you might as well throw the bullets by hand.

Ammor piercing 2200 feet per second……
Nick October 12, 2014 At 15:10

If I’m gonna go for 5.7, I’m getting one from FN. The ps90 is only a bit more expensive, is title 1, probably performs better, and looks a hell of a lot better than this pile of scrap MPA put together.

Don’t get me wrong. That stock looks nice, as does the front grip, but the gun itself is just hideous. The grip is at an aesthetically unpleasing angle, probably uncomfortable too. The frame looks like cheap stamped metal reminiscent of mass produced guns made decades ago (grease gun, sten etc). This thing makes a liberator look nice.
Larry D October 17, 2014 At 21:32

It is a gun ban resistant weapon.

That’s my story and I’m sticking to it.
