Have you ever thought to yourself, “ya know what would be cool? A semi-auto SBR MAC-10 look-alike in 5.7x28mm!” If you have, were you sober at the time? Yeah, didn’t think so. MasterPiece Arms, on the other hand, thinks that there’s enough demand for just such a firearm and they’ve introduced a brand new SKU for it and started shipping them. From the press release . . .
MasterPiece Arms, manufacturers of the MPA MAC Line of pistols, carbines, suppressors and MPAR Rifles, , introduce the short barrel version of their popular MPA570SST rifle. Built for maneuverability in close quarters while providing extreme accuracy, the new rifle appeals to both home defense individuals and law enforcement officers.
Based on the standard MAC design, the MPA570SST-SBR semi-auto rifle with side cocker is chambered in 5.7x28mm. The 8-inch threaded barrel has a thread size of ½ x 28 and works seamlessly with the MasterPiece series of suppressors (not included).
A Picatinny rail on the receiver top and scope mount allows for placement of any sight or laser system and the MPA short aluminum quadrail provides more area for additional accessories. The MPA570SST-SBR is furnished with an MPA low profile buttstock and side folding attachment and a Strike Industries foregrip. Additional features include an adjustable front sight and one 20-round polymer magazine. Fully American made, the MPA570SST-SBR, ships in a hard shell gun case and offers a lifetime guarantee.
As with any SBR rifle, all NFA regulations apply. See your Class III dealer for more information. MSRP is $799.95.
Right. Just a couple problems here.
First and foremost, the MAC-10 is nowhere near what I’d call comfortable or ergonomic. The sights suck, the placement of the safety is uncomfortably difficult to actuate and the thing just looks butt-ugly. Unless the gun is a real, full-auto MAC-10, there’s no way one is finding its way into my gun safe. Ever.
Second, who thought that 5.7x28mm was a good cartridge choice? Yes, it’s the same round FNH USA’s Five-seveN handgun and PS-90 rifle use. But with such a relatively limited user base, ammunition is damn near impossible to find. Federal only does one run of it every year, and while the shelves may be plentiful right now I guarantee they’ll shortly be looking like the Krispy Kreme box at a weight watcher’s meeting. If I want a MAC-10, I want it in the original 9mm flavor — cheap, easier to find and much more fun to shoot.
Lastly, why in the world would I want a factory SBR version? Now, not only do I have to spend my hard-earned $800 for the pleasure of owning this thing, but I have to wait a month for the ATF to send up a puff of white smoke just to get it to my FFL. And then it’s another 6 to 12 months for the ATF to sign off on the transfer paperwork so I can actually take it home with me. All the while, I’ll be sitting at home waiting with bated breath for the call to come in that I can pick up what may be the worst gun in the history of the world ever.
That statement isn’t just based on my intuition either. I had a chance to put my hands on one of these at a friend’s gun shop and hated just about everything about it. The stock was flimsy and didn’t feel solid against my shoulder. The grip was uncomfortable, as expected. And the whole package felt like it was made of pot metal. It was like someone took a bunch of Pringles cans and welded them together, then sold it as a gun.
Gee, I wonder why MasterPiece Arms doesn’t want to send us anything to review . . .
