Thanks gents for sharing info and your support!  

The "lawyer pin" is an unavoidable (to our legal counsel, and we concur) necessity. Its only purpose is to bar it from being installed on receivers not marked for 45 degree compatible FIRE engraving position. A 45/90 compatible receiver will have FIRE or suitable pictogram located at 68 degree, thus either a 45 or 90 degree selector will point to it sufficiently, enough to avoid confusion as to what condition the weapon is in.

The pin itself is pressed in, and made of stainless steel. We don't recommend nor suggest its removal, as somewhere between SAFE and FIRE doesn't mean safe or fire, for someone unfamiliar with the operation of an AR, this is a problem. For those of us that have been trained and are safety conscious, it isn't an issue as we go by feel, not by looking at which way the selector's indicator is pointing. But we can't assume everyone that buys it operates their AR that way.

There are now quite a few 45/90 degree selector compatible receivers, the latest being CMT, Aero Precision, and Midwest Industries. Spikes Tactical and Seekins will be out soon, as well as our own  

It's been three years since its introduction, we're gratified to see that the short throw movement is gaining momentum. It has never been our intention to replace the 90 degree legacy selector arrangement, we simply want to make the short throw selector a viable option, so folks can decide for themselves which they want to use. To that end, we don't license the receiver design, we freely give it to manufacturers that asks for it  

As to other short throw selectors that do not require a compatible receiver, the only one our legal counsel would be happy with is the Noveske STS. At 60 degrees, it points close enough to the FIRE engraving to avoid causing confusion. I'm not a lawyer and can't give legal advice, but I will share the reason behind ours a little further. Somewhere between SAFE and FIRE is neither SAFE or FIRE, it would not be easy to argue otherwise in front of a judge. While ATF may be fine with pirate or zombie themed markings, a neither here nor there position, such as a 45 degree selector will point to in the absence of a compatible receiver with proper markings, opens itself to litigation.

The lawyer pin, while inconvenient, makes the selector more time consuming and expensive to make, and limits its wider adoption, is preferable to law suits. For us, it's either the pin, or no short throw selectors.
