So I decided I'm going to build this rifle from scratch. It'll cost me a bit more, both in individual parts cost, and in tools I'll need, but I think I'm up to it technically, and I want to. The flip side to that is I can buy the parts separately, and spread the cost out over a couple paychecks. In fact, I'll be forced to because a lot of the parts I want are backordered.
The Cav Lower is in at the local gun pusher, so I'll pick it up tomorrow. Pics will be posted.
