I want to buy the B.A.D.-C.A.S.S. 45 degree short throw switch.
I am going to have to dremel that extra piece of metal off.
I know it will void the warranty.

Can somebody explain what Dremel attachment to use?
How long will it take?
Do I need a vice?

PM, if necessary.

Don't use a dremel, just use a file. And yes you will have to take that extra piece of metal off in order for the safety to fit inside the lower receiver. It took me 10 mins with a file to do it while I was sitting down and watching tv.

Can you tell me specifically what type (grit?) of file to use?

I want it to come out perfectly.

Just use a standard Dremel cutting wheel the small fine one and it will be off is a matter of seconds. Then hit it with a jewelers stone of some extra fine emery cloth.

I have 3 of them on various lowers.

I know the rule of thumb is to cut the cheaper piece, and for a very good reason. But is the slot that would need to be cut in the lower so the safety would fit, too difficult or risky to make? Or simply unnecessary?

Unnecessary and risky. Just grind off the nub. I believe the nub is there for lowers that have the safe/fire markings in the correct location for the 45 degree selector, but correct me if I am wrong.

Yes, there is a lower that has it's markings to match the shorter throw safety. But I'm not sure why they made the lower with a notch and the selector with the nub

Liability reasons, because of the selector not pointing at fire when it is actually in the firing position.

I just used a hand file and took my time.

Just use a simple metal file and take your time. I secured mine in my vise and slowly took off metal until it was flush with the body of the selector. You can barely tell anything was there.

There is NO reason to chop up your lower, just about any cutting or grinding bit, or file will solve the issue on the lever itself.

It is so complicated.

I ground the nub off of mine with a Dremel and a small, cheap grinding stone that came with an old cheapo Dremel rip-off I bought several years ago. IIRC it took less than a minute and it was done.

OP note that if you haven't already bought the lower, the ones from Rainier are notched for the 45° safeties.

i used a flat jewelers file, then a round one

when it looks close, see if it will drop into the lower; if not keep going and checking

I did it.

I bought a cheap cordless dremel. I used the disc shaped grinding stone. I was extremely careful and got it done just right. I then used a polisher for good measure.

I should have taken a picture because it looked great.

I used some blue thread locker on each screw.

After function testing it worked great.

I cant imagine not having a BAD CASS on any future lowers.

It looks and feels great.

Special thanks to Roger from BAD who helped explain the dovetail feature and the recommended switch lengths.

:eek: lol

The lawyer pin isn't for folks in this forum, its intended purpose is almost complete lost for well trained, and safety conscious shooters.

That said, I did modify one of my lowers to allow the pin to go through, and I know folks that have done it too, as they're planning on having a new FIRE or pictogram engraved at 68 degrees. If you modify the receiver, I'm pretty sure the manufacturer will not do warranty work on it. We're pretty easy to work with, as anyone that's had interactions with us can tell you. By this I don't mean to imply anything, especially when it comes to the removal of the pin, only that though the lawyer pin's removal voids the warranty on the selector, it's true only of the selector center, everything else is still covered under our life time, unconditional warranty, and we will still provide support for it. :)
