 Why not more PWS Love?

Other than the captive charging handle which is a little weird it seems the long stroke system has fewer springs, parts, weight etc.

PWS seems to have the only "different" system out there as far as AR's are concerned.

I recently purchased a MK110 upper for an SBR build and it looks great. Have it on a pistol lower waiting for stamp approval. I have not shot it yet because the whole pistol thing seems silly to me.

What happened to your piston system?
PWS discontinued the retro-fit system due to the overwhelming amount of inferior and non-mil spec components made available to the market in 2009. We have since developed the MK1 piston driven upper and rifles and will produce and market those from this point forward.

http://www.tnwfirearms.com/ar_gas_piston_kit.shtml

TNW has developed a low-pressure, long-stroke gas piston design. Why a long stroke? In order to keep from "hammering" the bolt as the short stroke designs do. We have slowed down the acceleration of the bolt mass and instead accelerated it over a greater distance. The result is less shock forces on the system, longer lasting parts and reliable feeding. It's the difference between unlocking your bolt with a ball peen hammer or accelerating it on a cushion of air!

An AR pistol is like a PCC - a compromise weapon foisted on us by FDR signing the 1934 NFA. Within those legal constraints, it can be pretty handy - or it can serve as a legal placeholder, as yours is - and mine, for a different legal placeholder reason. It's still fun to shoot it.

After looking at all the piston systems, I thought PWS had the best design. No spring over the barrel exposed to high temperatures, no cups to break, just a piston rod like an AK. Also, they have good barrels, button-rifled stainless steel with nitriding. I like the 1:8 twist as well; more flexible across all bullet weights than the 1:7 or 1:9.

Be careful. Since you aren't praising LWRC some will say you are some kind of fanboy who only signed up on this forum to promote PWS. Your 1,879 previous posts are just a cover.

This is only my 3rd post since joining the forum so I guess I should be careful - I'm just a lurker and use the forum mainly for information. But, I would like to give recognition to a company when credit is due.

I did a lot of research on piston systems and wanted to hold off on buying anything until I had a chance to see/feel the products at the 2012 Shot Show. After the show, I ended up going with the PWS MK110 upper and I feel that it is a great product. Granted, I don't have any other piston systems to compare it to but it fulfilled my expectations. I also went with PWS based on my interaction with them at their booth.

These two designs couldn't be any more dissimilar. Long stroke = piston diameter in relation to its length of travel.....that is it. The TNW still operates like the short stroke pistons on the market, the piston just travels further.

The PWS is very AK-like or Daewoo if you've ever cracked on of those open but it still has a full length carrier so it is capable of full auto use on registered machine gun or full auto service lowers.

Why not more PWS Love?
Because; There is only one Gun and LWRC is his prophet!!

Seriously the piston forum somehow became the domain of that one brand and its loyal owners simply attacked other brands as if that one maker built a good piston gun. Most other piston owners of various brands simply stayed away or were driven away.

Now, as for me, intimidation has the opposite effect being I was born in the Briar Patch so have no problem being bashed by a dozen zealots..

Usually this attitude occurs when a product is less than deserving but the odd thing is this attitude about LWRC is so not required. The LWRC is a splendidly built weapon and while I prefer the lighter weight, better balance with a better (IMO) concept of design as well as a considerable saving for equal performance in the PWS I still have the greatest respect for the LWRC and in truth would likely have already bought one except for the bad attitude of many of its owners.

Considering how nice the LWRC, LMT and POF are I would not mind having one of each just because they are all beautifully engineered and built weapons

In fact, I was ready to order the new SPR which looks to be a great weapon and IMO was built to counter the lack of PWS attributes found in the standard M6A2 carbines (Lighter weight and DI like neutral balance). I was able to ge a great price from my local FFL ($2,200.00 out the door) but it dawned on me I was spending an extra $700.00 to get an LWRC clone of the PWS (conceptually and purely IMO) so decided to buy another PWS MK114.

That has more to do with back up if there happens to be a future AWB. But, why have one when I can have two???

That said I still think LWRC makes a great weapon and will likely succumb to its charms. As long as I keep coming here and get bashed by the LWRC Jihadist I am unlikely to buy one.

One interesting thing. My FFL (A LWRC dealer I might add) had never seen a PWS and was very impressed. When I said it was lighter and better balance he said he could not tell any difference. He pulled out an M6A2 and sure enough they weighed about the same and balanced about the same. he was indeed correct. However, the LWRC was a 10" barreled SBR so I have to think the comparison was not apples to apples.

I just smiled.

There's lotsa PWS love! I like their stuff. I'd like to have one of the .308s and a 12.5 inch 5.56. It's a good company, and a good product.

I run an older style PWS conversion.
I used to install ther conversions and have the fixture to do so..
One day they just stopped calling us and changed theri product line.

I sill love my conversion. Runs smooth as silk but was EXPENSIVE! I never even switched from my strait SS piston to the new coated one. I just leave the new piston in my bag just in case.

I like it becaus it does not add a new spring to the system.
It didnt catch on well becasue there are so much cheaper alternatives.

The price of admission. Most people won't pay the prices PWS go for brand new when AA and Osprey (short stroke) do the same thing for less money.

Love my old PWS/ADDAX GPU.
Best combo of the Daewoo, FAL, AR on a AR receiver.
Really the only thing that could possibly top it might be the XCR.

They might do the same thing, but it's the WAY they do it that I like.
To me, with the mechanical/technical/engineering mind of anylizing how they work, I think they do it best.
Now, if the Daewoo DR200 was layed out a little differently, it would have no competition
other than maybe the XCR.

As a reloader, I am enjoying the 300BLK. There's an almost unlimited selection of bullet weights and styles that a shooter can try depending on interests. The cartridge is fun in full-auto and would no doubt make an excellent choice as an LE or personal defense round.

What distances have you been shooting? What zero?

Zero'ed at fifty yards. I haven't shot much beyond 100 yards. I also haven't done much yet with subsonic.

Anyway, I've had really good results with Sierra's 125gr Pro Hunter. It feeds well and shoots great!

I think there's plenty of PWS is love, considering if you purchase 1 today you would'nt see it for about 8 weeks! It maybe longer now.

Yeah I got a lead on someone that had one in stock.

I did have to wait 2 whole days for it to arrive. It was agonizing

No love...really? Seems to do alright here...along with ruger. I dont see too many over the top LWRC fanboys here. Hell...Im a fan...would be a bigger one if the rent wasnt too damn high! ar15 is a great forum and seems to have a more respectful crowb! I had a major issues with m4c and early on. I called out one of their senior members on the DI or nothing crap and got lamb-based not to mention banded! The admins are not neutral...not to mention I never insulted a sole until I just couldnt take the flaming anymore and even then never insulted them...unless you considering using the reports, facts, testing, and publishing...I insulted the crap out of a few ot these guys...but they had it coming! And if you could have guessed it...it was a heated piston vs DI...I sited army report, congressional hearing, etc some of the best sources and I was still torn apart without any substantial argument or evidence to debunk my argument. Lets just say we dont have righteous fanboys that are douche bags here...I like it here and general the flaming is low and the members have great respect even for noobs...because we were all noobs at one point or another! Just too bad those douche bags at m4c are like that...and I wasnt a noob at the time either!

The situation I was in over there was unbelieveable I was getting hammered by someone who claimed they had spent all this time over in the sandbox yet managed to have over 12k post! during the time in which they were there...it was a little over 2 years! I dont know about you but 12k post in a 2 year period for someone that had all the "Colt" experience there made me wonder...how did he have that much time to be on the internet? Sorry to hijack this thread but my point is this is a great forum...with great members...the is tons of love here! Im one for the PWS love as well! I will have an upper soon! It will be on my knight lower Should be pretty stellar!

SPENSIVE!

that's what I said. SPENSIVE!

I'm starting with Osprey and then Adams arms. Eventually would like a PWS just cuz i'm excessive like that. I want em all. Like hotwheels but better.

My bet would be AA is probably selling the most units. (huh.. I said "units"). But PWS would be close behind if they could get em below 1K. Say $850? Times are tough. Value of my house went down $200,000, gas is up, ammo went down but will go back up in about 6 months. I think its just hard for folks to put down more for an upper what other companies are charging for a whole gun. Thanks to me I've got other guys at my work addicted to firearms but they just can't stomach that much money for an upper so they chose AA.

I'm also getting sick of the quad rail stuff. Uncomfortable and heavy, although PWS looks lighter. I've been building with pencil barrels and plastic handguards and have come to love the feel and lightweight. My quad rail S&W feels like a cinderblock now. A PWS with light barrel and MOE handguards for $850 would be the ticket.

If you follow their Facebook page, they'll give updates as to where they are shipping rifles and who has what in stock.

I placed my order for an MK114 upper on 01-24-12. It was on my doorstep on 02-01-12. PWS is in Boise, I'm in Orlando. Not too bad in my book, especially since they shipped for free.
