None of those existed in the fifties.

Because you can do better if it's a GPMG you want.

If you mean those actual prototypes, it's because they broke all the fucking time.
Also the gas system doesn't handle heat as well as a piston one.

What's with that shoulder thing going up?

>>34838647
Most of those early attempts used existing AR/M-16 upper receivers, cut up and converted to belt-fed. The receiver, bolt/carrier and gas system aren't robust enough to handle it in the long run.

The Shrike is one successful attempt to convert the platform to belt-fed. Ares' business model in selling the Shrike sucked and pissed a lot of folks off. But the product works well. It's robust and is reliable with both belts and mags. The upper was designed from scratch to be a belt fed upper, not a converted one.
