The M60 machine gun - a classic summary

just noted this pic of a corner bunker on the main compound up in Camau. Never know when you are going to need a "back-up" firearm. Although I would think it a better idea to have the ready ammo all set up to be immediately available, so you don't have to rummage around for a wire cutter to be able to shoot. Plus, who knows how well maintained these were. Maybe rusted in place for all remember.

What a picture. The VC/NVA weren't the only ones who lived below the ground. Most A-team TOCs I've been in, and even 5 SFG HQ TOC, were under ground. I think the exceptions were in places where it was impractical of impossible to dig.

There are some mechanical quirks in the early designs that were addressed later, like gas pistons, flimsy trigger group retention, weak feed cover pull compared to the E3+ models. Some fundamental design issues remain even with the latest variants. This revolves primarily around the bolt and operating rod. The bolt lugs chip in the corner from violent barrel socket engagement. The post on the op rod has a very small engagement surface with the bolt. Consequently contact pressure is quite high along with ware. There are certainly better methods of operation, but this one works well when maintained with good condition parts.
Here's the bolt lugs. Having a blank or snap cap as the last round in the belt helps save the bolt by slowing it down rather than have it slam home with no resistance on an empty chamber.
This bolt has less than 500 rounds on it and you can see wear has already begun.
Here's the op rod. This one being E3 variant with second stop notch to help prevent the runaway gun issue.
Note the skinny little post I was talking about on the op rod. It likes to beat the day lights out of the cam path in the bolt. The bolt likes chew a crater in the front of the op rod post where it drives the camming action.
Here's how the two operating parts that hate each other orientate in the gun.
