Is it the fact that it is a direct impingement system that blows unburned power and crud back into the receiver or is it something else?

None. It's perfect.

One could argue the bolt design, but KAC and LMT has solutions for that.

Needing offset scope mounts might be a downside, but it let's you change handguards and barrels.

I am surprised no manufacturer made an alternative recoil system that is more robust and better for the AR rifle.

Government profile barrels have a weak point at the back of the gas block journal.

Carbine gas guns are tougher on bolts.

While this is true it is also the reason that the AR is one of the softest and easiest rifles to shoot.  It is a mechanically efficient design where the BCG doubles as a piston.  There is less mass reciprocating versus either a long or short stroke piston.

...and then they retrofitted short pistons into the thing!!!

Interesting note that the current rifle of choice for CAG and DEVGRU is no longer a 416 but back to DI M-4 type...hmmm....
The USASOC URGI is a DI M-4 type...hmmm...

Like our military did with the failure button?

Some people religiously believe it should be there. If I can, I build with Aero no FA uppers.

At least my answer is honest.

Lots of little springs and detent pins that get easily lost. Doesn’t run as well as other weapons when not properly lubricated. Suppressing it can be tricky. Buffer tube is somewhat flimsy.

Good news is the AR is easy to assemble and disassemble with huge aftermarket accessories.
Bad news the tiny springs and some roll pins can be a pain to get in flush.

The bolts tend to have problems with high round counts. Ejector, gas rings, even the bolt itself can break where the cam pin goes in. With that said, an extra BCM bolt is in the safe for each rifle I own. I don’t lose sleep over it.

I change mine to the BCM gun fighter one or strike industries charging handle.
The standard one is fine but I like the extra surface to grab on the BCM one.

This, by far.

A relatively thin aluminum tube that, if bent a little, can utterly incapacitate a rifle. I’ve seen it happen.

This "crud" has to go somewhere be it the bolt carrier group (which is a piston itself) or in a dedicated piston. Either way you are going to have to clean these parts with enough buildup.

Do you encounter slam fires on your AR as a common occurrence? Have you ever had a slam fire once? M1 Garand's have a free floating pin, but I don't hear people complaining about it.

A very small chance of a round going off if sling shotted into battery the momentum can set off a soft primer but the hard rifle primers will make this less than .0001 chance.
