Anyone noticed this from Ra tech?

[Sig]

Ra tech have made upper and lower receivers for the WE M4s. Don't know what the material they used is.

One with trades would have been good.

Have to wait and see. They put trades on their pistol slides, so they might follow suit. I'm more curious about the material used to construct the upper and lower.

A person once told me that VFC use 6061 aluminum in their upper and lowers.

If they are forged they'll be aluminium. Bet Viper-tech are the ones OEM'ing them.

Even though I don't have a WE GBBR, I'd rather get one without trades so I could get my own engraved, same for any receiver that isn't well engraved.

The lowers are forged, I think, probably out of untreated 6061 and almost certainly by Taiwan Deer, not Viper. Taiwan Deer also provide the receivers for RA-Tech's other forged M4s.
