We here at Irvington arms are now certified retailers/installers for PWS' gas piston conversions.


price is 400 installed.
if the taper pins need to be milled out, add 20 dollars.

we have carbine & mid-length systems available now, with rifle systems landing next week.

Frank, I, and Jenny took out 2 ARs and ran them through the ringer. the three of us were thorough impressed.

keep your action clean, cool, and increase reliability!

can you post pics or a link so we can see what it would look like. When you say installed, does that mean that we have to send our upper to you for you to do the conversion. Will this work with all uppers. Varmint, bull barrel, free float, more info please.

FEATURES:
*Dual Diameter Piston For Better Alignment and Less Wear
*QD disassembly for cleaning
*Operating Rod attached to carrier to minimize carrier defection and receiver wear.
*3 setting adjustable gas system with gas shut off for “Bolt Gun” suppressed firing
*All machined and heat treated parts, nothing welded or cast
*No machined modification to carrier or upper receiver

The system will add approximately 4 ounces of weight to your rifle. The gas block is the heaviest piece at nearly 5 ounces, but the gas block and tube that you take off will obvoiusly subtract from the overall weight.

The rails we know the system will work with are the DD Lite Rail (LOVE IT!), the new Omega Rail from DD, the VLTOR CASV rail (a modified version that VLTOR is making for us) and the LaRue rail. We will have all of those rails as options for purchase during the retro-fit of your rifle.

Below are some pictures that might shed light on the function of the system along with an excerpt from our site:


Function

When the rifle is fired, the developing gases expand inside of the gas block much like a traditional DI system. The expanding gases push against our short stroke piston which exerts pressure on the operating rod and thus gives momentum to the bolt carrier. Once the piston itself has traveled 3/4", it expels any unused gas from a small vent in the bottom of the piston tube. As the cycle of the action is already in progress, the piston moves to the back of its chamber awaiting the return of the operating rod to push it back into battery.

System Features
Available for Carbine, Mid and Rifle lengh systems
A dual diameter piston for better alignment and less wear
Carrier key and anti-sheer pin machined from S7 tool steel
A fully mothered operating rod to inhibit flexing or bending
QD disassembly for cleaning
The operating rod is attached to the carrier to minimize carrier deflection and receiver wear.
Adjustable gas system for firing unsuppressed and suppressed
All parts are CNC machined and heat treated; no welded or cast parts are used
Lifetime Guarantee

Will the system fit a JP Ent. barrel and under a JP handguard?

No it won't. The JP HGs are to low.

Not currently, they're working on a few things for the JP stuff. We're now a JP dealer as well and will be looking at ways to incorporate the PWS system onto the JPs, may not be pretty at first, but it'll work :p

I'll be out tomorrow should you just wanna try out the thing ;)

Works with some of the free float HGs, will work with barrels that are med or full contour, unfortunately not the skinny ones at this time.

You would have to send your upper to us for the installation, it is not an at home drop-in kit.

I attached a few pics of it installed with the FSC comp. I'll take more and update our site accordingly in the next couple of days.

I'm not sure. I would need to see the rail system. It may work with modification.
