I'd also have to say that the XCR would probably be your best bet. Don't get me wrong, I love my AR180B to death. The key problem with the AR180B is finding one for sale. On top of that, you would have to add several accessories to even approach a somewhat modular state, unless the previous owner has already done them.
Let's say you get a hold of a stock AR180B with no accessories on it. First off, you are going to want to buy a 2 stage trigger of some sort since the stock trigger sucks. If you want to change the stock, you're going to have to buy a stock adaptor for whichever stock you are looking to put on it. If you want to scope it, you are going to have to buy a QD scope mount, or have a gunsmith permanently attach a rail to the receiver. And finally, to add rails to the forend, you would have to buy a Midwest Industries Tactical Forearm.
When you consider the cost of these extra parts, it really wouldn't be all that much more expensive to get an XCR, which as mentioned, has the option of caliber conversions.
