[@dansmajd4105]

@Militaryarmschannel Tim, in the first video you have put CLP on the piston rod, which very firmly discouraged in the PWS manual. The use of lubrication on the pistod assembly may cause to excessive fouling, creating almost a concrete-like buildup on the piston. This may lead to reliability issues!

[@Prodigysportsman]

time stamp?

[@mattwalters6834]

@@Prodigysportsman you’ll have to check his first PWS test video.

[@mattwalters6834]

Interesting, I’ve heard that you want to lubricate any piston driven weapon on the piston area to prevent fouling; CLP or break free CLP doesn’t do that?

[@Mrgunsngear]

PWS rifles have always ran well in my experience 🇺🇸

[@metropolitanfirearms5192]

Mrgunsngear Channel yea, us too. Great rifles for us...

[@jameskobi6111]

Can vouch. I'm approaching 5K rounds with my mk116 mod 2-m, and I shit you not, I've only had one malfunction, and it was a failure to eject with wolf steel case.

[@jsmorefield]

I have had PWS rifles before they had adjustable gas piston systems with some teething issues but no other issues. Love their rifles especially shooting suppressed.

[@tucknroll8057]

I had a bunch of issues with my MK111 Pro last November. 3 times getting PWS involved before it was fixed, I spoke with Dean over the phone and he claimed PWS had never tested their rifles with anything higher than 55 grain ball ammo so left me concerned to say the least. Mine couldn't get through a full mag between wolf gold, magtech M193, and Federal XM855. The experience was terrible tbh after it was finally fixed after the thrid time i dumped it due to how the experience left a bad taste for PWS as a whole.

[@tucknroll8057]

@Charles Lindberg Yeah their customer service leaves alot to be desired. Dean admitted on the phone there was about 4 people besides myself that he just couldn't figure out why our guns wouldn't work ans i bought new ammo and mags to test it everytime. When i got my gun back after its final trip to the factory it just arrived with no paperwork or anything explaining what was done to fix it. Also it had a different adjustable gas block where the settings were different compared to what was listed in my manual so imagine how fun that would be. Glad i sold that piece of shit.

[@ronhendy5228]

Great video. I have a PWS MK116 Pro with over 2500 rounds through it without being cleaned. Runs 100% all the time. When the grip gets hot I switch to the BCM vertical grip. Keep the great videos coming. Thanks

[@datzitteezy]

An affordable gas piston rifle. I've owned 2 of these. Love em

[@m118lr]

Finally, decent view from behind Tim out toward the targets..great change of pace! REACTIVE is the ONLY way to go..

[@PracticallySquared1]

I have 2 pws MK-111’s one mod 1 in 223 and one mod 2 in 7.62x39. Love them. The 7.62x39 needs cleaned a little more often then the 223 but I shoot them 100% suppressed and I think the cheap 7.62x39 Ammo I shoot is a big part of that. I’ve went over 2500 rounds suppressed with the 223 gun without hiccup. Only cleaned it cause I started using it at my bedside!

Definitely have to clean that gas tube with a 40 mm brush, every time you clean the rifle though. I’ve had my bolt stick because of buildup in the gas tube

[@devildog1989]

He's addressed this numerous times. They fog up on him. I have the same issue, I have yet to find a pair of safety glasses or goggles that don't fog up after 2 or 3 rounds getting behind a a rifle, I guess its my breath coming back off of the cheekweld. Idk. I don't see the point. I wear corrective lenses normally anyways but every single time I shoot prone or off a bench, FOG.

[@MGood-ij1hi]

The fact that you're willing to show to the viewers any flaws that you find in the products used in your videos , even high end named products like Steiner, proves to me that you're not a pitch man for the gun industry and that your evaluations can be trusted.

[@theshootindutchman]

Thanks for shooting the steel, we can hear the hits😊!

[@Frogman007able]

Hey Tim would you be able to run this kind of test with the mcx virtus patrol people claim it can 20000 rounds before something goes wrong?

[@boygonewhoopdataZZ]

Any AR can do that, just going to need a new bcg around the halfway mark since every gun is over gassed for reliability

[@tanhelmet]

Great Video. The only thing that ever breaks (or weakens) on gas piston upper (98% of the time) I have owned a CMMG, an LMT , an ADAMS and my Buddy's LWRC and POF. the extractor loses its springiness ot resistance and/or ,it actually breaks. We upgraded to the Stoner HD. On in case the a spent primer fell into the trigger housing. It was an interesting repair. The LMT had issues with the buffer so we swapped it out for a lighter one. The ADAMS/Sig was almost identical to the HK MR556 in design.

It would be interesting see this done with the cherrybalmz lube as it doesnt run off or burn off like CLP tends to do especially with DI rifles.

[@Arkanic]

Thanks Tim, it's a hard job but someone has to do it. LOL. Maybe try reinserting the same batteries a couple times between mags on the next run to see if you can reproduce the earlier issues with the Steiner. Got a 2nd gen Vortex UH-1 on the way myself, looking forward to running it through it's paces.

[@A8vscRrabbit]

You need to get out there and hit range with a weed eater or a brush hog, Tim. Range needs maintenance🍻 I have to clean and redesign my range too

[@networkproblems8523]

Same thing happened with my sig romeo5 (the 3rd one I bought). Not sure why, but reseating the battery 3 times did the trick. Shock from gun fire seems to have solved the issue of electrical contacts inside...

[@Rocksteady713]

So is it safe to say if I buy another bcg/piston I should be good for lifetime and more

[@timallen6035]

[@HabeasJ]

@WiffleballTony its a known fact that likes on the Gram tighten your groups and lowers your split times

[@whowantsachannelwhowantsac7910]

Like other piston AR's, I assume the piston (unlike AK's) is not part of the BCG. If that is the case, sticking in the piston cup or anywhere in the piston system would not affect travel of the BCG or the charging handle. Maybe I missed that episode?

[@mattm8314]

The PWS uses an AK-like long strong piston system, not short stroke

[@whowantsachannel1983]

Matt M thanks Matt! Obviously I missed that episode.

red dot should have etched dot to make them still usable even if something goes wrong with the battery

[@zxrider9246]

Tim have you ever tested the IWI Zion-15 ?

[@kspeacekeeper7894]

Tim, granted I can’t see all the brass but looks over gassed. Have you tried turning the gas setting down?

[@ryangowin1988]

How could the piston keep the charging hangle/carrier from moving? Isnt the piston and rid independent of the carrier on the pws gas pistin design? Im thinking something adhering or binding the carrier to the piston rod or the causing the bolt and or carrier to bind.

[@tfunkhou88]

Nope, it’s a long stroke system, the carrier, rod, and piston are all connected

[@SuperDimi111]

MAC, I have 2 of the PWS Mod 2, they do stick like that as well in mine. My theory is that piston head upfront is what’s sticking to the piston. Unless weight of the long stroke rod is settling weird on barrel extension.

[@JWbabyshark]

Mac how do you like the compensator/ flash hider on this rifle?

[@mattwalters6834]

I’ve been wondering about it as well.

[@wesleypipelayer7627]

What happened to the BCM endurance test ???

[@riffraff9000]

I would use lithium primary (non-rechargable 1.5V) batteries instead of those alkaleaks.

[@CrimeVid]

Michael Cox I’ve never had that happen.... unless I have put a dead piece of kit aside,... and forgotten it for a couple of years. This is pretty much a non issue at the moment. The non rechargeable lithium batteries are not very good for low draw purposes because they have proved to have a relatively short in-use life.

[@mattyp3154]

I had an eotech that did a similar thing. The sight would only work with brand new batteries for a mag or 2 then it would die

[@Florida_War_Tribe]

So I bought a MK114 mod 2. I am getting some drag marks from the cam pin on the upper receiver and it’s snappy on the recoil. Does anyone else have the same problem? Side note if I turn the gas over to a different position it won’t cycle even with green tip.

[@GOTM413]

The POF roller cam pin seems to be a good fix for the cam pin drag.

Yes, we constantly sent our 512 optics to eotech For repair. They were on full auto colts though. Probably a non issue on a civilian rifle that will never see the volume of fire a military or LEO rifle will. Early model Vortex strikefires has this issue as well.

[@joeyassyrian]

They cool off faster and are lighter, I have a lot of quad rails including the BCM QRF and DD RIS, they take a little longer to get hot but they also stay hot for longer periods of time. You're going to end up in a similar situation regardless if you don't have a VFG or some type of rail covers.

​ @Military Arms Channel If you don't adjust the gas setting often the fouling will lock that adjustable piece in place, been there done that. When the piston starts to bend and the fouling starts to lock things up the flare of a PWS piston AR gets really dull. The way it's designed doesn't allow any user serviceability, it's not a correct piston AR in my mind, only half way. They should have designed the whole thing to work like a proper AK bolt not half ass it with a tiny piston shaft that bends and has multiple pieces and the ultra fouling adjustable gas block made me run away from my $1100 investment.
