Or, some of us have been using DI AR's professionally for years and even decades now and know better than to fall for a marketing ploy like piston AR's. Adding unnecessary parts to a design that works already is not an upgrade.

US Army Ranger Capt. Nate Self, whose M4 jammed into uselessness during a 2002 firefight after their MH-47 Chinook was shot down in Afghanistan’s Shah-i-kot Mountains, offers another case. He won a Silver Star that day – with another soldier’s gun – and his comments in the Army Times article appear to agree that there is a problem with the current M4 design and specifications.
SOCOM appears to agree as well. While US Special Operations Command is moving ahead on their own SCAR rifle program with FN Herstal, they’re also significant users of the M4 Carbine’s SOPMOD version. By the time Capt. Self was fighting of al-Qaeda/Taliban enemies in Afghanistan with a broken weapon, Dellta Force had already turned to Heckler & Koch for a fix that would preserve the M4 but remove its problems. One of which is heat build-up and gas from its operating mechanism that dries out some lubricants, and helps open the way for sand damage.
In response, H&K replaced Colt’s “gas-tube” system with a short-stroke piston system that eliminates carbon blow-back into the chamber, and also reduces the heat problem created by the super-hot gases used to cycle the M4. Other changes were made to the magazine, barrel, etc. The final product was an M4 with a new upper receiver and magazine, plus H&K’s 4-rail system of standard “Picatinny Rails” on the top, bottom, and both sides for easy addition of anything a Special Operator might require.
In exhaustive tests with the help of Delta Force, the upgraded weapon was subjected to mud and dust without maintenance, and fired day after day. Despite this treatment, the rifle showed problems in only 1 of 15,000 rounds – fully 3 times the reliability shown by the M4 in US Army studies. The H&K 416 was declared ready in 2004.
If someone asked me what I thought of a diesel Jetta for a commuter car and I thought a gas powered Civic was a better option and I could explain why, I think it would be perfectly reasonable to do that.
I use one professionally as well
BUT the op asked about a particular platform and a particular rifle not on opinion why he should go the opposite way he just suggested and wanted info about.
- I'm interested in a diesel powered car, tell me all you know about them.
- Nah you don't want diesel, come let me show you these gasoline burning models, that's what you want if you ask me.
What do you guys think of the Ruger SR556 (or other piston AR's) for 3 gun?
I said I think the piston guns are marketing ploys. That is what I think of Ruger SR556 (and other piston AR's) for 3 gun and everything else.
You mean the norweigian 416s that overall are spanking the c8 sfw on service life and hard use under adverse conditions? OR M27s being used as both squad auto and dmr rifles? Or more and more sf units including alpha gru units dropping their "ubiquitous" aks for 416s?
I may not need a di gun least of all for 3 gun matches, but well at least one of them definitely has their uses.
