PWSs stay just as clean as any other GP AR.
The crud, unburnt particles, and gasses are sent out the front out of the gas block. Barrel fouling is on par with anything else. AK's tend to get filthy because most AK ammo is inexpensive but the tradeoff is it is filled with cheap, dirty burning powders and corrosive primers. |

They run just as clean as other piston guns.
The exhaust port is in the piston tube, aft of the gas block. The majority of the crud that usually comes into a DI chamber is dumped here. I have owned LWRC and PWS. However, not at the same time. I find the PWS to be balanced better and lighter in weight. Recoil pulse is less than the short stroke. The long stroke system does not have the metal to metal impact that the short stroke does, pros and cons to the piston and DI system |

There is no comparison, Piston guns run much cleaner DI guns. Piston guns are so much nicer than DI guns suppressed. Completely different experience. After 1 mag suppressed with DI the gun is literally filthy. It looks like it has hundreds of rounds through it. Freaking mess. Piston is a non-event.

The most I've ever run through my 16" 7.62x39 PWS AR upper in a single range session is 120 rounds. I clean the rifle after every session (an easy operation that takes very little time in comparison with my DI uppers).
Currently running Wolf 7.62x39 ammo. For that ammo and number of rounds, everything past the 2nd piston** (and towards the BC), is clean. Maybe just a thin film of carbon that is easy to swipe away with a cloth. The bolt, BC and parts of the upper receiver they inhabit are clean, with just a bit of carbon and some brass on the bolt face, and a little carbon on the bolt lugs. Easy to wipe away. I really like the system. Works well in my experience. ** The PWS piston actually has 2 separate "piston" parts that expanding gas from the barrel port would see; one at the far end of the piston rod which gets the bulk of the carbon fouling, and one an inch or 2 closer to the BC. |

Well, clean after every session, if that makes you happy.
I have 3 PWS, 2 older Mod 0 and a Mod 1. The Mod 0 are my trainers which get shot about 3 times a week. Each gun gets run for 6 months then I clean it and switch to the other gun. Yes, the piston rod is very dirty after 6 months and by then the bolt is almost as dirty as a DI gun after 30 rounds I don't ever shoot my DI ARs anymore. They were sitting waiting for Hillary to win and me cash in so now they just sit all lonely never get to go anywhere It is odd to think how my pistols require more cleaning than my AR pistons. Plus the unique design is what allows me to go so long. I would never run a standard piston 6 months without cleaning. The carbon build up is in a small chamber with a small piston while the PWS is a long op rod that gets the carbon collection so there is no place that affects operation. It is similar to the AK but is actually sealed away from the BC area where the AK is loose fitting and tends to bleed carbon into the action |

I am getting very curious about the PWS gas system. I might have to pick up an upper to try sometime along.

Thanks for the input!
I guess I may look for a MK114 on sale. I really like the FSC so that's a plus for me that PWS sells them already pinned and welded on. |

I have a PWS MK114 and planning on adding another. The piston rod and head does get dirty, but bolt/carrier stays very clean and the lube does not dry out like DIs after 200 rds. I don't really clean it per say, just more like pulling out the carrier and wiping down the piston head and put a little lupe on the carrier. Thats all. Been doing this every 500-600 rds. Gun has a little over 3k rds on it now and never an issue. Its very accurate to boot too. One of these days I am just going to keep shooting it and not bother to clean the piston just to see if it impacts reliability.
I also have an LWRC IC and it runs clean like the PWS. Its piston cup design is advertised as self cleaning. I haven't shot it enough to test their claim. Also, my DI just sits now. I only keep it around because of sentimental value. |

I have the MK114 in .223 and a MK116 in x39.. LOVE them both, but I shoot the x39 more due to how cheap ammo can be in that Caliber.. NOT REALLY a fan of the Mod 2's I wonder why..

I'm running both an gLWRC ICA5 and PWS MK114 Mod 2. Really love both platforms for each of their unique characteristics. Mod 2 is just so well balanced and I dig picmod. The whole pws system is super slick looking and operates smoothly!

I prefer the LWRCi design. My PWS upper didn't seem to like my lowers due to the BCG design, had to get it its own lower and a PWS receiver extension since it was hanging up inside other extensions. Just something to note, works fine now.
DI guns get dirty faster, but shooting suppressed everything gets dirty so I end up cleaning them at about the same rate (basically after everytime I shoot one suppressed), haven't put enough rounds through any one of my ARs in one sitting to experience where they foul up at different rates. |

I'm not going to debate the PWS against the KAC......
As far as bolt life, a standard bolt will go around 10k. I've worked aircraft for nearly thirty years. I understand the ideology of preventative maintenance. No part will last forever, not PWS or Knights. I have more than one rifle, I highly doubt I will wear out what I have in my remaining lifetime. The PWS is intriguingly me because of the AK like operating system. But I do despise the Commie AK. The Mod 2 is damn light for a piston gun, it's balanced well. Some have complained about it lacking a FA. Funny how no one complains about a FA not being present on the LMT MWS308 or the Knights SR25, two damn fine battle proven rifles! In the end......it's your call. There are merits for both systems. If we entered some "Red Dawn" like scenario, and I could only have one rifle, it would be a DI But that really is another invalid point. If a gun broke in a scenario like that, I would not fix it, I'd find another rifle. |

Have any of you guys shot 5.56 ammo out of these uppers..?? How did it perform Accuracy wise.. Asking because I have some IMI 5.56 69gr that didn't do so well in my MK12 Mod 1.. So I'm just trying to shoot them all before I grab more IMI 77gr.. But my MK114 LOVES the Wolf Gold.. surprisingly good groupings..

My Mk114 Mod 2 rifle, Mk116 Mod 1 and Mk116 Mod 2 uppers shoot Aysm 77gr OTM best
Every 5.56 factory load had shot ok, but I've never gotten better than 1.5" groups, 2" is usually the norm. The Asym is consistently right at .5-.75"......I believe most of that is me. |

How did it go with the 69g IMI in your MK114? I have the same rifle and was thinking of picking up some IMI. They appear to have a little more zip than other 223 ammo with the same SMK bullet. Btw, I can get 5-shot groups of about 1 to 1.5 MOA with 55 grain Wolf Gold when I do my part. That's with a 4x scope, prone and just resting on the magazine. I'm sure a better shooter on bags and a 9x scope could easily get sub-MOA with Wolf Gold. For 30 cents a shot, it's really hard to beat. I'm curious about the 69 IMI in the context of shooting 500 yards in wind and wondering how much better it might buck the wind than the 55s. |
