IF no one is aware, who's going to complain?
That's the big issue, getting caught

Unless there is an interference problem the FCC will likely just ignore slight indiscretions

Newer FRS radios have 2 watts out on channels 1-7.
(see link in previous post) The Midland radios can be bought in the bubble 2 pack.
A small increase to 5 watts out really isn't going to be noticable (with the same modulation and antenna gain. The 8 watt Baofengs usually put out about 5 watts. The GMRS "License" is for 10 years, $70, and applies to you and any immediate family member. Communicating with FRS radios is legal.
There are a FEW legal issues with a non- type approved radio though.
FCC approval is just one of them.
An approved FRS radio cannot select illegal frequencies from the KEYPAD. The FCC does not trust you

Higher gain antennas (equivalent to more power) can be used with Baofeng but not legal with FRS.
Out in the wild or an isolated shooting range these low power (my base ham rig is 200W, my mobile 8 Watts)
are not likely to interfere with nearby users. Most ranges are a few miles from anyone that would complain.
With many LEGAL radios operating at a sporting event, one or two ILLEGAL radios will not be noticed.
I don't actively search for FRS/GMRS radios on my property but if I suspect people are hunting/trespassing I sweep the bands, find their frequencies and TELL them to leave.
I have no need to complain about anyone buying and using these radios. They are not likely to cause ME any harm. (I also have a few). The 600/1000yd range I frequent uses the newer FRS (with 2watts) and will allow you to bring your own. I would not WANT to cause them any issues with illegal radios so I bring my Midland.
