How you doing guys? Malak over at Modern Pawn. Today, we’re going to be talking about the PWS MK2 series rifles.
These are PWS’s. AR-10 style rifle. They are chambered in .308. I think this right here is top three as far as heavy carvings that you can buy today. I think it is a solid top three. My top three right now for quality .308 fighting rifles are the MK2 from PWS, the FN Scar Heavy, and the LWRC REPR. I think those three are the tops rifles on the market now. Pick your flavor. All three of them are awesome. Let’s go over some features of the MK2.
The MK2 comes like this out of the box. You get a set of Magpul flip up sights. Magpul MOE furniture. You get a billet mold upper and lower receiver. One of the nice feature about the new MK2 is the handguard. They used the VLTOR KeyMod style handguard that gives you a full picketing rail across the top with the no gap. That’s a continuous model and style picketing rail across the top. You get this KeyMod system on the other three sides of the handguard. What it allows you to do is keep a piece of rail where you need a piece of rail. These little modular pieces, they go in and out real easy. All they need is an Allen wrench. They hold real tight.
It gives you the ability to put rail where you need rail. It also gives you the ability to put other things besides picketing rail on your handguard. For example, and iPod adaptor. This one here, we have an KeyMod adaptor on the bottom of the rail. There’s also some hand stock kits that I’ve seen some light mounts that will go directly in here, so you don’t have to put a piece picatinny rail then a mount for your light on top of that. It eliminates one of those interfaces, and it gives you a nice clean smooth feel.
It also helps reduce some weight by taking off some of the material where you don’t need that material. The upper and lower have a very nice match billet upper to lower look. It’s not just like a basic forging. It is a nice looking billet. You can see, for example, here they do some extra riving to keep everything a little stronger. The trigger guard is milled in. It’s not a pinned-in trigger guard. The four assist is nice and milled in. It’s not a pinned on piece that some of the heavier upper receivers use. It has a little bit of a flared magwell. The PWS MK2 also uses PWS’s very cool buffer system that has the built in flush cups. The riving has a different style attaching to the lower receiver that helps keep things a little more rigid.
It helps eliminate the castle nut and the retaining plate. The PWS ships with the PWS FSC brake. Very good quality brake cuts. Ton of the recoil keep the rifle nice and flat. It’s not a crazy flash monster where you’re just getting huge amounts of flash off the end of the rifle.
The barrels on the PWS, you have several different barrels to choose from on the MK2 system. You have a 12 inch, a 14.5 inch, a 16 inch, and a 20 inch. You have all the way from SBR. This is a 14.5 inch with the pin flash higher that gives you a non-FA 16 inch overall length. You have the 16 plus the flash higher, and a full 20 inch barrel system. The barrels from PWS are extremely high quality.
They’re isonite PQ coated barrels. If you’re not familiar with what that is, some other companies do a similar process called melonite. It is a ferric-nitro carburizing, which is a fancy term for hardened high-corrosion resistant high-lubricity, high-wear resistant treatment to the barrel. It is not technically a plating. It is a barrel navel surface treatment. Works very well. LWRC also uses a ferric-nitro carburizing on their barrels. It works really well. It’s been out for a while now. It’s time-tested and proven. It gives the barrel, I think, more accuracy than a traditional chrome lined barrel.
The trigger on the PWS ships with an ALG QMS quality mill-spec trigger. We put this on the gauge and it came out average. About a three and a half pound trigger. Very nice quality trigger for a mill-spec trigger. If you wanted to put in a nicer trigger you can always get a gizing national match. It takes standard air 15-style triggers if you want to choose gauge or a single stage, or you want something particular to your needs.
It takes any standard air 25-style trigger. It does ship with a BCM gun fighter charging handle. The rifle has a adjustable gas system. One of the nice things about the new mod ones from PWS is the adjustable gas system. These allow you to run suppressed heavy loads, lights loads, really tune the gas system to make the rifle as soft shooting as possible. Another nice thing about the PWS, we’re using standard SR-25 magazines. You can get the DPMS’s or the Magpul’s. The Magpul are our favorite. These are excellent quality magazines, 20 rounders. They work excellent. These rifles are chambered in seven six two by 51 nato. It will obviously shoot .308. The overall weight of the rifle is eight pounds, nine ounces on a 16 inch rifle. Obviously, the longer barrels will be heavier, and the shorter barrels will be lighter. Eight pounds nine ounces. I think it’s a very reasonable weight for this style of rifle. It’s not overly chunky. I’m sure you can get 15 pounds worth of gear on it after you put the scopes, and bipods, and all kinds of real pieces, and lasers, and lights, or whatever.
A raw rifle as it sits right here is eight pounds nine ounces on the load. The PWS MK2 uses the same style system as the PWS MK1 series, which is their five by six lineup. You have a full stroke gas system. It’s a little different than your standard directing gas impingement, and your short stroke gas systems. When you pull that piece out right here, that’s pretty much all of the components of the gas system coming out of the rifle with the exception of the gas block. The way this gas system works is it uses a full length gas piston system. This piston head at the front here sits inside of the gas block and butts up against this face is what creates the seal.
The pressure from the buffer spring pushing the bolt carrier groove piston group forward. Makes contact with a ported face inside the gas block. A gas block puts pressure on this, and pushes the bolt carrier groove piston group backwards. As you can see here the charging handle is basically connected to the whole groove. This is the way things have to function. With this right here, you have this that goes back and forth inside there.
If you want to get the charging handle off, it’s not a big deal. You twist this front piston extension and it keys off the end. Then your charging handle will come off, and you have your bolt carrier group. You have several lightning flats cut into the bolt carrier group. What this does is it reduces the bearing surface of the bolt carrier group on the upper receiver, and inside the buffer tube.
What that allows you to do if there’s any dirt or grit that gets inside your upper receiver it’s able to channel it away, and not bind the bold carrier group inside the rifle. I took this particular rifle out in about a 25 mile to 30 mile an hour wind day. We were shooting sub-MOA groups with Federal Gold Medal match. 168 Federal Gold Medal off of a bench, and a bipod. The rifle also shot about an inch and a half with 147 grained PPU bolt ammo. Bolt .308 ammunition, which inch and a half with PPU is pretty a pretty good grove from my experience. Some of the best bolt guns I own won’t shoot better than an inch and a half with PPU.
That’s about a one inch group. That’s a one inch group.
