That is my understanding as well.Maybe I'm mistaken but aren't most AR's direct impingment? Some are piston operated but those are usually described as such.

Piston guns usually have two advantages:Maybe I've got it backwards.
Probably, it's been a long day.
Piston driven is what the Captain really meant.
i always assumed, may be wrongly, that the real benefit of piston driven ones can be seen on full auto models only. with semi-auto it is hardly justified, at all.Maybe I've got it backwards.

Some see an advantage of a piston system when running suppressed...i always assumed, may be wrongly, that the real benefit of piston driven ones can be seen on full auto models only. with semi-auto it is hardly justified, at all.

Everyone and their mom makes a piston AR-15 now. We go over the pros/cons of going piston, the best piston AR-15 uppers, and also the best conversion kits.www.pewpewtactical.com
IIRC if you're running a suppressor, piston driven can be an advantage. What's the chance of THAT happening in the PRM? Of course, an adjustable gas block (for DI uppers) can help there too.i always assumed, may be wrongly, that the real benefit of piston driven ones can be seen on full auto models only. with semi-auto it is hardly justified, at all.

My two favorite piston rifles:You might consider simply buying a tried and true piston gun that does not rely on an AR platform lower. If you're in MA, they are mostly AWB friendly and nearly all of them take STANAG mags. Love my ACR and have had great luck with the SCAR - there are other less pricy piston guns on the market by Kel Tec, Sig, IWI, etc.
The biggest reason for my question is my son's interest in the WWSD rifle. He wants one but we will probably NEVER be able to get one in this god-forsaken state.

I find mine smootherThe main advantage of a piston AR is that they tend to be easier to suppress (AR-180 derivatives like the HK 416 and AUG) than a DI AR. If suppressors aren't in the picture, I don't think there's much reason to favor piston over DI.

a polymer lower rifle - why?The biggest reason for my question is my son's interest in the WWSD rifle. He wants one but we will probably NEVER be able to get one in this god-forsaken state.
Completely anecdotal evidence but I have to disagree with this. My LMT piston AR ran flawlessly, literally never once had a hiccup. Never used a suppressor with it but had a dozen 2K round training sessions with it. You could probably make the case for the "piston kits" IMO they are garbage. I wouldn't hesitate to use another LMT piston as my battle rifle.However nothing piston will run as smoothly as a direct gas system especially if there’s no suppressor or selector switch present.
