Vigilance Rifles, a company which product line primarily consists of large caliber (.50 BMG, .408 CheyTac, etc.) bolt action and semi-auto rifles, has entered the market of pistol caliber carbines by introducing a 9mm PCC called M20. The M20 is a straight blowback operated gun firing from a closed bolt and yes, fed from Glock mags. It is available in pistol (8″ barrel) and rifle/PCC (16″ barrel) configurations for the civilian market, as well as in a form of a select-fire submachine gun for military and LE customers. Let’s first watch a short video showing the full-auto version in action then see what features Vigilance Rifles M20 packs.

The receiver of Vigilance Rifles M20 is machined out of billet 6061-T6 aluminum and has a Cerakote finish. The receiver shape allows having a large square bolt and enough space left for the action to cycle within the dimensions of the receiver. The AR buffer tube, which the gun is shown equipped with in most of the pictures, has no mechanism inside it and is merely used for making the gun compatible with AR-15 stocks. The AR buffer tube is also mounted on an adapter that allows folding the stock.

The M20 has a single piece receiver with a machine gun style hinged top lid. The latter can be opened in a matter of pressing a button providing access to the bolt and allowing to field strip the gun. There is also a safety mechanism built into the lid that blocks the firing pin when the lid is open making an accidental discharge impossible when disassembling or servicing the gun. The iron sights are built into the top lid. The Picatinny rail section mounted between the iron sights is low profile and doesn’t block the sight picture.

Another key feature of Vigilance Rifles M20 is the quick-change barrel design which makes it possible to easily swap barrels of different lengths or detach the barrel for ease of transportation. The barrel is retained by a large 2″ barrel nut and its disassembly is a toolless process. Currently, the M20 is offered with an exposed barrel as shown in the pictures (a signature design seen in many Vigilance Rifles firearms), however, the company does plan to make a handguard or rather a barrel nut extension in the future.

The M20 PCC utilizes a mil-spec AR-15 trigger mechanism and takes AR pistol grips that don’t have the rear beavertail extension. The non-reciprocating charging handle and the magazine release button are located on the left side of the gun. The bolt is made of chrome-moly steel with induction heat treatment in the wear areas. The firing pin is made of a nickel alloy steel. The fixed ejector doubles as a magazine stop. The gun also has a controlled feed extractor that engages the rim of the cartridge at the beginning of the feeding. The M20 is compatible with 9mm double-stack OEM Glock mags, Magpul PMAGs, and ProMag magazines.

The MSRP of Vigilance Rifles M20 PCC is $1699. This configuration includes a carbine length barrel with an installed muzzle brake, folding stock, Picatinny rail and one 10-round ProMag magazine. The pistol length barrel set is sold separately for $399. The M20 comes standard in Graphite Black Cerakote color, but you can order other colors for an additional $99. Vigilance Rifles M20 is made in the USA.

It’s always exciting to see a new firearm design. Despite having some parts borrowed from the AR-15, the M20 has a lot of interesting design solutions. In fact, the company has applied for 13 patents to protect some of the most unique design elements of this firearm. Tell us in the comments section what do you think about Vigilance Rifles M20.

    Ok all you negative reviewers, here is the bottom line. First, I'd bet
    most of you haven't fired a Vigilance M20. I have and I own one. the
    M20, is one of my favorite firearms to take to the BLM and Seven Mile
    Range. It Is comfortable to shoot. 9mm makes it far from expensive to
    shoot. heavy, yes (I guess if you are a weakling, but there is little
    to no recoil because of the weight. I put a 50 round drum on it, 45
    rounds thru it no issues. Next I put three 33 round mags with 30 rounds
    thru it. Next I put 4 ten round mags thru it. 45 rounds in the 50
    round drum. I repeated the same drum and mag scenario. Over 500 rounds
    of CCI, with no issues. Cleaning was a piece of cake. The M20. comes
    apart quick and easy, making cleaning fast. Reassembling quick easy and
    fast. And as a side note, demokraps, would consider the M20 as a scary
    gun......guess its because its black (BLACK GUNS MATTER). My
    suggestion to all you hatters, go shoot one then review the Vigilance

      @Cymond A. I did not copy and paste anything.
      B. A trace of my IP address would show, NOT the same as vigilance.
      C. Before you post nonsense like you did about me, I own a M-20, have put many rounds thru it, HAVE YOU.

      D. You don't have to like a perfectly good product, that's okay, but to attack a person on their review is in extremely poor taste.

    How the hell could anyone with even the tiniest fraction of sense think this was a good idea to manufacture? Staggering, simply staggering.

    I mean seriously staggering.


    If you own stock in these guys, dump it now.
