Primary Weapon System Piston Retrofit Kit

Archangel · 01-24-2008, 16:45

Has anyone had any experience with this system? I don't want to get into a Piston -vs DI debate as it has been hashed out here and every other weapon forum in America.

Anyway, I have spoken to Todd (the owner) on several occassions and he seemed to genuinely care about taking care of his customers. The only PWS product that I have is the FSC556 and I'm pretty happy with it.

At $400 + a 10% MIL discount, it doesn't seem like a bad deal if one REALLY wants to get a piston upper. I'm leaning towards one since I use suppressors on my weapons and wouldn't mind less blowback in my face.

Thoughts?

Dude, why don't you just send it to LWRC for a retrofit? Their system is more proven and they also offer the mil discount.

For less than $400?

Not going to happen for $400......My brother and I rebuilt my own on LWRC company machines and it still ran me $300. Nuff said

PWS is a vendor for LWRC for flash hiders and compensators. Not piston systems as some have been mistaken. That being said, LWRC will not field questions about PWS piston system and vice versa.....they are all good friends and would like to remain that way.

Not saying to buy LWRC or PWS. Op rod is a bit slender for my liking, I just like more robust systems.

PWS does make excellent muzzle brakes......loud, but great.

There is a guy on another forum that has one of the prototypes and has several thousand rounds through it and loves it. It is so new that I doubt that you will find that many with any serious round count racked up on it. I love the concept behind the systems but since I don't have a can or an SBR I can't justify laying out $400 for one an a rifle that runs just fine without it.

I called those guys back in October and asked if that was even possible and was told that it is, but that they weren't going to do them for non government contracts.

Odd, not the case from my last conversation with a company rep whom I know to be reliable (28 years worth of reliability). PM me the individuals name and I'll run it to ground for you. Sounds like someone fed you a line of BS, I have my suspicions of who, just like to confirm. I'll also get you a no crap price and timeframe if you are still interested.

Not all of us are young single bucking studs like you anymore. Some of us have crumbsnatchers to feed.

Last I checked, LWRC's price for a conversion was still over $1,000 with my MIL discount and (unless I am misinformed) the LWRC system did not give me an option for gas adjustment when using a suppressor.

jbour13 - Glad you're chiming in on this one. I had the pleasure of meeting your "source" at the Expo here and fully intend to follow through with a conversion. It'll have to wait until a couple higher priority expendatures are out of the way, but I'm looking forward to it. Even went to the trouble of getting another upper expressly for the purpose. Nice product and seemed like a decent crew all the way around. Wish I'd gotten there with more time to BS; it was closing and they had already started packing up the toys. My regards to all.

i've got one (PWS piston conversion - new build actually), but need to put some rounds through it. with the new baby, i haven't had much time to shoot. i opted for a midlength setup -

That Aimpoint T1 in that LR mount is really growing on me. I would love that on my SBR, but I just can't justify the $640 price when I can pick up a M3L in a LR for $400.

Either case, great looking carbine.

Just curious, did you decide on a ML for the asthetics of it because with a piston system, the advatages of a ML gas system is moot.

Why are they snatching crumbs when they should be picking up brass? Who's in charge around there, anyway?

ETA: The Micro T-1 in a GG&G mount will ride on my 10.5" M6A2 when it comes in. You can borrow it anytime.

Yeah, the 3 year old likes the warmth of a full diaper and you want me to try to get him to pick up brass?

WHAT?!!! You're finally coming over to the lowly Aimpoint camp? This I've got to see. Whatever happend to the wrong-eye dominant thing? Personally, I like to leave my Aimpoint ON between deployments. I like to see you try that between drills with your 553.

Wish I could make it to the Paul Howe instructor course with you, but I'm trying to work a deal to fly Paul down to train our boys at our facility (when it gets completed). Hell, if it works out the way I expect it to, I'd like to invite a few PS members down.

To be fair I thought about it and it was June and not October and I spoke with the sales manager and one of the tech guys, they had me on speaker phone. I cannot for the life of me remember their names.

the T-1 is my new fave optic - i really like it. i wanted a ML piston system because i thought (without thinking much about it) it'd be softer shooting than a carbine piston system, just like a ML DI and carbine DI system. turned out that it is. that was the main factor i considered, not any other piston vs. DI advantage/disadvantage.

i shot my ML piston side by side with a carbine PWS piston carbine system and mine was noticeably softer shooting. the carbine PWS gun had a similar feeling impulse to the LWRC rifle (which i've found a little harsher than a DI), while my ML PWS was the same or softer than a carbine DI rifle. go figure.
maybe it's the added weight of the longer ML piston rod, because it'd seem to me that the amount of gas bled off is the same in a carbine vs. ML piston, since the front components are all the same. mine was the first/only midlength PWS had made at that time, and when todd at PWS test fired it, he himself was also surprised to find noticeably softer shooting.
