this sytem interest me in several reasons. one, it is low profile enough to be compatible with some rail system right off the bat. the excellent Daniel Defense system is one of them. no modification are required to the rail.
the system are front loading so you can retrive all piston components for cleaning without removing the rail.
the gas adjustment in the front offer a few positions that can be used in various operaion requirement. you can shut off the gas and turn this into a bolt gun for covert sniping.
the system is high quality with a reasonable price, with the DD rail, this conversion is approximate 300.00 or more less then the competition.
the stainless gas knob will be finished in production version to be less refective.
the bleed off or the gas vents are behind the gas regulator. as you can see from some of the vent holes on the rail system, the gas regulator is working quit well.

the gas key are modified direct gas key with a embedded stake inside to keep it from breaking apart from the punishing piston strikes.
the long rod are inside a protective tubing which has some vent holes underneath to help clear any dirt or grind.

We move right along over to the POF booth, the other civilian available piston manufacture. being this their home base, POF had a very large presence at the SAR show.

re-post from another thread
I have not shot the PWS nor much with the POF, but I do have extensive trigger time on 416 and the LWRC
As far as the limited time on the POF, I find the gun has a very well developed timing and balance. Only disappointing thing is the tall rail system. I keep looking forward to the low profile version, but POF is so busy with the current projects, they just don't have time.
POF systems are well made and it seems to be very reliable. During a past Bortec show, they had their gun running all week under sand and winds while other guns seem to have spotty performance.
PRO: reliability, ease of maintained
CON: rail system
I have had this LWRC upper that they send me for about a year plus. I have not cleaned it, and usually just a light coat of lube and it is off running. It did cough up a few Wolf ammo, but I am leaning more on the bad ammo side, then it was the gun's fault.
The standard h buffer and spring just don't do the gun justice. I upgraded to the heaviest 9mm buffer and also an up rated spring, it tames the recoil a bit and lean turn the gun more like a HK 416. Without it, the recoil impulse is flat and seems straight back but a bit heavier hitting then a DI gun. With the upgraded buffer, it is almost as smooth as a 416. I wonder what a 416 buffer assembly would do for this gun.
The gun was assembled and shipped to me with my LMT upper, the upper and the barrel was overlapped so I have to adjust it a little to get it function 100%, other than that the gun has been spotless.
PRO: reliability, easy maintenance, standard rail profile, light weight,
CON: more recoil.
Nothing more I can say, it is smooth, and butter smooth and recoil felt are almost non-existent. It is fairly accurate, as accurate as any DI I have every shot except for the LMT MRP...interesting when the MRP piston surface at Shot 08.
PRO: the best piston gun on the market, reliable, ease4 maintenance, and thoroughly developed engineering piece.
CON: high price and unavailable to civilian....This might change by 2008 with Wilcox.
PWS, I am sending an upper to them for conversion.
From what is told to me, this system will be on par with the rest of the field and it will be more competitively price. You will get a Ferrari at a corvette price. I am definitely looking forward to running it side by side with the 416 and the LWRC.
I want to stress this is only my opinion, someother's might vary. in the end, i am still a DI gas gun man... I can only see the piston as a speicalized segment product for those that goes in harms way that require the ultimate reliable hadji killing system. guys with CQB-R and suppressors should most welcome this trend.
Simpliest and the most effective upgrade to any AR platform.
Extractor spring upgrade...I just happen to have a Bravo Company kit that consist of a upgraded spring, rubber o-ring that is made with a more durable material that will withstand the heat from the super heated gas, lube and solvent.
Many company offer this upgrade, Bravo, CMMG, Specialized Armament. I have been using the Speicalized Armament upgrade spring with a LMT o-ring in all my bolts.
one other ovber look items, and some said is a overkill is the magazine follower. I always highly recommend the excellent MagPul anti-tilt follower. I make sure all my mags are equipped with this prosduct.
The standard green follower is on the spring compare to the Magpul.
All those toys are great looking on a weapon like flashlight, ACOG/magnifier or NVG, but the weight associated with that, REALLY cramps the speed when you have to shoot. Personally, I would stick with my good ol' bare bones M4/16 with iron sights...might not see in the dark, but in MOUT, they are actually better in my opinion...but thats my opinion.
I also might comment on some of those fancy barrels with muzzle suppressors...fluted barrels are nice, if you plan on firing a ton of ammo fast, Or sniping, but again, its the weight in the end.
What I find amazing about the pictures of the guns, is it seems every one is jumping on the piston band wagon....
SGTM Lee....on the HK 416 you were taliking about, were you talking about a dual piston system like on the latest Russian rifles, and the LR300?
