DBM questions

[PappaSmurf]

So I am new to the bolt action realm and am kinda confused on the whole Detachable Box Magazine thing.
I am currently awaiting my "delay" process to be over. I purchased an Axis 2 in 6.5 creedmoor with a bull barrel in ATACS camo. It came with some kind of scope so I was happy about that, but that is the extent of my knowledge on the rifle so far. I plan on setting it out to about 300-400 yards.

My main concern with it tho, is the 4 round mag. I have seen the 10 round mags have been made but cant seem to find any available. I also have seen people that are modifying some to make it higher capacity.

I am inquiring as to the DBM, is it as simple as buying one in a short action and throwing it on and then getting some AICS mags? OR, would it be more feasible to just buy some regular stock mags and then modify them?

Thanks for any advice and information that you can spare.
