Yes I tried to do a forum search and had poor results.

I am strongly considering a PWS 16" piston upper to go on a three year old Daniels Defense  DDM4 which of course is a Direct Impingement gun.

I think that I can keep my Buffer and spring and the only thing I need to do would be switch uppers

Am I missing something?

This is the Warden's  (wife) gun and she won't be pleasant if it doesn't run.

No I won't sell the DD Upper.  I buy guns and parts, I don't sell them.

Thanks for your help!

There is a piston forum on here that can provably better answer your question.  Have you considered a piston kit such as Osprey or Adam Arms?

Piston Forum? Who knew?  Thanks and no I have not checked the others.

Since you already have a nice upper I would just throw a kit on it.  I love my Osprey.

Why do you want a piston upper? What's wrong with DI? There are fewer high quality piston uppers out there than DI, and they alone tend to cost more than a solid, complete DI gun would cost.

Yes I know I have a great Armalite Upper and better Noveske Upper and the Daniel's Defense is no slouch either.  I just feel the need to own a Piston in  my mix.
I have been told the piston has a little less Kick and I am certain the Warden (wife) would like that.
I want her to have the best!.

Stick with normal ar's

Ar's already have a piston, its integrated into the bolt carrier group

You would benefit more from a good muzzle brake


Really,  there isn't much a "piston" ar offers that a "DI" ar hasn't offered for the past 50 years

If you're worried about the recoil, then go with something using a midlength or rifle length gas system, heavy buffer, and quality muzzle break. I would stick with DI personally, as I don't see any reason to buy a piston upper unless you're trying to clone a 416, which I doubt you are.

While they do tend to be heavier, they also have more mass going back and forth.  I never actually heard of any piston AR shooting softer than a DI one.

Nothing wrong about adding a piston AR to the collection, but if you want a  light weight, soft shooter for the Mrs then I'd go a different route.

have a smith add an adjustable gas block to a DI AR, put a KMR or other LW forend on it, buy a nice muzzle brake/comp, feed it lower powered 223 ammo and she'll love it.

This.  A piston gun is going to have more reciprocating weight, theoretically causing more recoil.  I've never done a side by side comparison so I can't say for sure, but the physics say your idea won't pan out.

If you want less recoil, get a muzzle brake, adjustable gas block, and standard carbine buffer.  That'll tame any recoil right down when tuned correctly.

Okay I have a Smith's "Good Iron" Brake that might not be "THEE Best" but I have it and will try that. mind you she put 5-600 rounds down range without a complaint. so it's not that bad.

That's what I've heard as well, buddy has a Sig piston rifle and while it's a nice one my BCM 14.5" lightweight midlength feels like a .22 compared to it, and the Sig is very front heavy. Piston uppers have their strong points but reduced recoil isn't one of them.
