Trigger guard and magazine suggestions

[400Bullelk]

I am about to start my first build. It is going to be a 6.5x.284, I am going to use a Predator action, McMillan a-5 Stock, 7.1 Broughton barrel. I would like to do a detachable magazine. I thought that Wyatts made one, but don't see it. What do you guys suggest?

Wyatt's Outdoor Detachable Magazine Assembly - Remington 700 .308, 7.62, Ultra Mags & .338 Lapua

Wouldn't the 300/338 mag assembly work for your x284?
