A Tale of Two Crush Washers, or Two Crush Washers One Barrel, and other AR oddities

Just because it fits doesn’t mean that it goes there.

This is a pic that I got elsewhere. A 5.56 flash hider was installed on a 9mm because the thread pattern was the same. 3 rounds were fired, with this as the result.View attachment 3960823

The first round didn't set off alarms for the shooter? Scary stuff.

What happened when you drop your BCG on a hard surface, and it lands on the gas key.

Replaced the gas key with a new one, using Michigun’s OCKS, and properly staked them.

On top of being damaged, in typical Fail Zero fashion the screws were not properly torqued or staked.

PSA put that barrel nut on a tad too tight.

I can‘t understand how someone would do this, consider it adequate, and charge someone for it.

First pic is not mine, but it is of a receiver endplate “stake” done for the owner at a local gun shop.

This pic is an example of a recent stake that I did.

Huge difference, not only in actual security, but in appearance. I’m definitely a “function over form” sort of guy, but if a job can be rock solid AND attractive, that’s the method I’ll use every time.

Looks like a screwdriver was used, the mark of a true professional.

Someone so dumb that they can’t figure out that 9mm is a larger diameter than 556!
