The piston guns are too new and dont offer the same low recoil as the direct impingement guns. Save some money and get what everybody else has. Maybe in 20 years they will come up with something that is actually good enough to make the piston guns worth while.

I hope this post helps some of you and good luck to the rest of you.

I just gotta focus on the bolded part... I'm pretty sure God forbid if JD dies 'cause of a DI system, he won't be defending it, he won't be doin' much of anything except getting eaten by zombies.

Well said. Except there is no urban battlefield scenario and hasn't been one since the civil war here in the good old USA. I shoot a lot of rounds thru my AR to the tune of 8-10k per year or more. If I were dumb enough to shoot all of those without cleaning oiling or maintaing my rifle then I deserve to have a fouled up and broken rifle.

If a pistol driven system is so great how come we don't have Piston driven shotguns?

DI is cheaper and DI has less recoil. That should be all you need to hear.

Default We DO have piston driven shotguns

The Benelli M4 is a piston driven shotgun... the Auto-Regulating Gas-Operated (A.R.G.O.) Piston-Driven System is also the heart of Benelliís R1 and MR1 rifles.

I can see BOTH sides of this issue. My .02, stick with DI until piston systems are ubiquitous and the parts are readily interchangeable. There are too many proprietary AR piston designs, albeit each with their own merits. In times of need, I personally would prefer to have readily available parts... from ANY vendors' bin to bring my weapon back to operational status.

Forget about all the other comments on this thread. The real answer for why there are so many of both is this:

1.) a lot of people had regular AR's and wanted to buy something new and different.
2.) a lot of people saw their neighbor buy a piston AR and decided they needed one, too.
3.) people have too much money to spend.

There you have it. People always want bigger, better, newer, different. You can get into all the details about how the two types work better or worse for shooting guinness world record-level groupings, or how one is more reliable than the other when stuck in the jungle/desert/mountains/etc against an army of blood-thirsty enemies soldiers... but, of the millions of AR-based rifles in civilian use, how many are shooting world-class matches at 600 yards or battling to the death in the demanding climates of wherever?

Most people take their rifle to the local range and send a few boxes of lead towards a paper target sitting 100 yards away. Then they go home, have a beer and watch TV. Flip a coin to decide, because either rifle will be just fine for them.

I thought another reason for piston guns was a lot less heat in the action. I personally don't care either way. If recoil is an issue for you with a 223 then you might want to stick to air rifles. To the poster that said the military wanted cheaper ammo that isn't true. It was Macnamara the bean counter that wanted the cheaper ammo. It's a battle rifle not a sniper weapon so who cares about that little loss of accuracy. The real problem with the M16 isn't the platform but the caliber. It's a damn varmint round. You should buy what you like. I get a kick out of people who think they are going to fight off the next dictator with small arms when the dictator will have tanks and aircraft. What are you going to do fight off the whole military while you take cover in a wood frame house? Gas or piston they both work get whatever trips your trigger.

I heard the .223 was adopted to allow infantry men the ability to carry more rounds per pound. You can carry two rounds of .223 for every one 30.06 round.

I would guess we have different views of urban combat than. House to house, or hut to hut, fighting in Bosnia, Serbia, Afghanistan, Iraq, short range jungle fights around drug labs in most of South America and lest we forget the lesson's learned in Somalia would all qualify as an "urban battlefield" environment.

Now if the argument was that this particular rifle would probably not see an urban combat experience due to it's location within the confines of the United States border.....

Well.....

The LA Riots
Katrina's Aftermath
Extended Power outages due to extreme weather

And then there is the Southern Border "issue".

I would say the chances of an urban escalated "event" are much higher today than they were 30 years ago.

And I still don't see someone shooting a DI gun to the point of failure in that type of environment as they would still probably be dead from exhaustion/dehydration or blood loss first.

Gas Piston AR's exist because there was a market for them and people could make money.

Its a damn good round for dispatching two legged goblins in the 55grn 1:12 twist barrel and bullet combo. The problem with it today is the 1:7 and 1:9 twist and 62 grn bullets have effectively neutered the round.
