So, I see the Oryx retailing for $399. That's obviously more than MDT's "teaser" price of $299, and Magpul's MSRP of $299.

The Magpul ought to sell for less than MSRP, and comes with a mag (bonus). It looks like the LOP extensions for the MDT cost extra, but so do the Magpul cheek pieces.

So, all up, the MDT is prolly ≈$100 more than the Magpul.

Still waiting...
