Does it have cut outs in the rear for a standard m11/9 adjustable wire stock? That would open options for stocks (Lage, Practical Solutions, US Machinegun) post SBR approval. |

I recently bought one of their recent side cocker Defender 9mm Micro's, the MPA930SST to be exact.
If you are looking to buy get one of the newest generation with the side cocker rather than the top cocker. The new gen has the new disconnector hammer that has completely done away with the horrid trigger slap the old models had (as well as all older Cobray semi auto Mac clones). Mine is deceptively accurate and easy to aim and shoot. I'm not keen on the safety, but it is what it is. It takes sten mags or the new tapco plastic mags. I bought a bunch of sten mags and use those as my past history using tapco mags has been spotty. The new plastic grip frame they use is relatively comfy compared to the old metal box grips. They've also bevelled the edges of the bottom of the trigger guard on the new models. The old models like the old Cobray guns would rub your middle finger raw after a day of shooting. The new bevels fix that issue pretty well. The side cocker model also now has adjustable pistol sights as well as the top rail. The old guns had the old metal flange and peep design which was kind of clumsy to use. The finish is also decent. Not like the finish you'd expect on a top of the line handgun but not complete crap. Executive summary: more or less the MPA guns take the design of the semi auto Cobrays and improve them in nearly every way. However IMO it doesn't suppress as well as you'd hope. I'm using mine with a Gemtech Multimount with either a blocked piston LID or more recently a fixed endcap. The pistol has a lot of port bark and the action itself is clanky, but the suppressor still takes the edge off well enough. Another "perk" of owning one of these things is that you can bump fire it like a machine. Everyone who has tried with mine has done it. I'm not crazy about doing it myself but it's insanely easy to do with this pistol. Now that eform 1's are back up I put it in for the old SBR treatment. I'm not sure if I'm going to get a MPA tube stock or get one of the USMachinegun stocks. I am going to get one of the USMachinegun forward grips though, those look pretty handy and don't appear to take up much space. MPA also makes a railed surround that locks to the ring on the barrel that fits over an installed suppressor, giving you extra rails for a VFG or what have you. |

Does it have cut outs in the rear for a standard m11/9 adjustable wire stock? That would open options for stocks (Lage, Practical Solutions, US Machinegun) post SBR approval. NO. NONE of the semi auto Cobray / Mac clones can accept the "wire" stocks of the open bolt SMGs. It is because the closed bolt guns all use what I can only describe as an "A frame" trigger bar that sits right where the sliding rails of the wire stock need to go. Also none of the semis even have the cutouts in the back to accommodate one. However all the MPA pistols have a threaded hole under the back section behind the grip where an L bracket can be installed. MPA, USMachinegun, Lage and several other places make L brackets for fixed and side folding stocks that can attach here. Edit: Quoted:I'm not sure. I have emailed several questions relating to both that and the ability to have one set up for using the Sig SB-15 in the meantime, along with a couple of other things... To install a Sig brace what you would need to do is buy one of the L brackets made by USMachinegun that adapts an AR stock. Install an empty buffer tube and go to town. Something to consider though is that if you go that route and use it like a stock the factory sights will be too low to use, you'd be better served getting one of the side cockers with a top rail and mounting an optic, perhaps on a riser if needed. |

Quoted: Lage makes a semi-auto version of their upper that can fit on the full size MPA pistols. I don't think they make one for the micros yet though.

something like this?
MPA45 with L bracket from USMachinegun, UTG folding tube adapter, SB15 on RRA Entry Tube 12" folded 21" extended (with the piece of foam from a pistol tube, 20" without the foam) for this, a better Aimpoint ring would be a "Lower 1/3rd Co-witness" as it sits pretty low on the GG&G as is. The stock sights are just TOO low, no matter how you rest the brace against your shoulder. http://imgur.com/F2uqs0A http://imgur.com/B8tDATP |

Quoted:
Doesn't the strap move it into aow status though? I've never seen an official ATF opinion letter on it (which doesn't mean there isn't one somewhere) and there are a lot of people out there who claim it is legal and a lot who claim it makes the pistol an AOW. Back in the late 90s during the ban I personally talked with the then owner of the Cobray brand who was of the opinion that the front straps were NOT considered to be vertical grips. My view on it is "better safe than sorry", but then again I've never found those grip straps to be all that useful on a semi auto pistol anyway. |
