Is it possible that at some point, you'll make a run of .50BMG uppers similar to the ones you made that were mounting on AR15 lowers (this: https://www.canadaammo.com/product/detail/da50-50-bmg-36-upper-receiver/), but matching to a NR AR10 such as the STAG10 or the BCL102?
I know there were problems with the barrels the first run, and maybe profitability wasn't exactly great, but maybe this time since they'd be NR right out of the box, and those AR10s are selling like hotcakes so maybe there will be a larger market.
