I'd prefer to go with something that fits in a Badger M5 inlet. I have had Badger and it's pricey for what it is. I have two Rem 700's now with PT&G flush fit and I like it. No problems. Only difference to me is that the PT&G is a glossier finish than the M5. If you have a stock inlet for the M5 footprint, it's easier to sell if you ever want to do that.
Also had the CDI and I'll never do it again. It has its own inlet and McMillan did not inlet mine deep enough and the mags would not feed without deepening the inlet. I never went through the trouble of sending back or sending to CDI and finally sold the stock and metal at a loss. Also, the CDI lever may need to be trimmed for feeding. The badger/PT&G is totally plug & play.
