Re: Badger EFR on a B&C Light Tactical?
LoneWolf,
I would highly encourage you to stay away from the McCann rail. They are having issues across the country and McCann is about as helpful as an anvil tied around your neck. Additionally, the McCann MIRS will cost more than your stock.
If you are serious about the UNS/MUNS, put it in an EFR type mount. If your stock can't handle it, get another stock. In fact, even if it goes into your current stock, I would do some serious research about whether it will stay put after the install. The way those stocks are filled may affect the way you can anchor the EFR. You will probably be milling completely through the aluminum frame built into the stock. For sure, make use of the front bipod stud to anchor the bottom of the EFR.
You don't want to go to the expense of installing an EFR and then having it shoot loose after mounting the extra weight of a UNS/MUNS.
