They can be. Excessive use of tracers is not a good idea for several reasons. It's not a bad idea to clean your barrel following any session with tracers.
A 2K weapon?... oh wait... you're talking semi-auto... my bad. I automatically think full auto, thus 15 to 20K per item... but I still use surplus ammo. All I can get my hands on...If they are surplus I would not risk it in a $2K weapon. Just me but not worth it and they are very dangerous as far as starting fires.
Ha... bull twinkies... YOU maybe. Most of our NFA guys have shot more than 5 times the amount of ammo the military would allow through their guns. They can replace them... we cannot (easily, anyhow). We have to keep shooting them, replacing barrels and whatnot. Military just scraps them out and issues new guns.... and of course they put far more down a barrel than you or I ever will.
Sadly, this is true. In IL, an officer could theoretically get by only shooting as few as 21 rounds a year to meet minimum standards. The unfortunate part is these guns are still just as beaten up as their high round count brothers as those who are averse to shooting are so with gun care as well. Now back to your scheduled program:Most cop shop guns never get close to service life of the barrels before getting traded in. Hell, most cops never shoot their guns all year except for qualifying done what... once a year? If they're lucky?
5.56 tracers are 63gr.Sadly, this is true. In IL, an officer could theoretically get by only shooting as few as 21 rounds a year to meet minimum standards.

Since I didn't see where you mention WHAT your $2k weapon is exactly, are you sure it will handle tracer rounds? Say if you had a 93 with a 1:12" twist rate, I would wonder if the longer 55gr bullet would stabilize properly due to its length.
M196 is 55gr. Commercially available Federal tracers are 64 gr.5.56 tracers are 63gr.
