Hey Guys,
I know there are a few threads discussing the IUR's and such but wanted to start a new one with a slightly different subject. I need to pick up a lower for the IUR en route to me. Colt's official response is any lower that follows the CAD or US TDP will work. How can I be sure the lower I eventually purchase will fit without issue?
I assume most manufacturers follow or exceed the TDP and the lug patterns will match. I want to avoid any sloppiness between the upper and lower if at all possible.
I am currently looking at the LMT lowers and am combing the EE for a Knights if anyone is willing to split up a rifle. Ideally I'd like to keep my SA20 together which is why I am sourcing another lower. Any other high quality lower suggestions would be appreciated.
Thanks
