Have plans for different upper so don’t want to invest too much money into the firearm. If I get the cheapest Mark IV, will it work with any after market Mark IV upper? |
TBD

Yes, any MKIV frame is compatible with any MKIV barreled received. Originally Posted By Princeton: On the Ruger MKIV the upper is the firearm so it really can’t be replaced. |

I'm not sure OP, but if I correctly infer what you want, it might be a better option to find one of the custom companies and buy a whole pistol that has the upper you like.

I got lucky and found another Arfcommer in my area selling one for a more reasonable price. The ones I found for sale on common parts sites were ridiculous. |
