What is the longest mag box for 700 want to go to 3.980 OAL

[boscodog]

I'm building a 338/300 edge and I'm wanting to be able to go to 3.980 AOL. I'll be using a stiller predictor L/A and I realize that the mag box slot on the receiver may need to be lengthened. My question is what is the longest mag box made, the longest Iv seen is the wyatts at 3.825 ID.
Than you,
Tom
