I'm having a hard time evening out my dragons temps. His ambient temps are 90° hot and 80° cool but his basking stone is on the bottom of his tank and it's reading up to 120° in some spots. I currently am using the arcadia 100w PR38 on top of the screen. I've tried raising the bulb up a couple inches above the screen but then the ambient temps drop down into the high 70s low 80s and the basking stone will sit at around 110° would a lower watt bulb fix this or should I use something else for him to bask on, I currently have a 12x8 slate stone for his basking. Also we are trying to beat coccida right now so whatever I use for basking has to be easily sanitized.

Real stone tends to absorb and hold heat, but it's good maintenance for their nails. Maybe move the stone so that it isn't directly under the basking bulb, just off the the side a little. Still in the basking area just not directly under the center of the bulb.
Right now he's in a 75 gallon tank. I'll be ordering him a zenhabitat (4x2x2) next weekend with my check. He is approx 4 months I believe. The guy didn't really know but judging on his size that's what I think (pics of size for guessing age, I forgot to ask how much he weighed at the vet)

Dragons don't warm from the bottom. You need to measure the temp of the light not the surface. You need a digital probe thermometer to be accurate. 120 degrees is to hot and will burn your beardie (for surface temp) but the light temp may not be that high. That's why we all recommend the digital probes.
It's possible your IR gun isn't measuring your specific basking surface properly. IR guns need to be calibrated to the specific surface they are measuring in order to provide and accurate reading. Most guns come calibrated to handle a wide range of common materials from the factory, but some materials that would be common within the enclosure fall outside of this range, which means the IR gun will be providing an improper reading.
Getting a digital with probe end thermometer solves two issues. One, it will be accurate and give you a real measurement of the basking surface temperature, and two, it will show you whether or not your IR gun is reading your specific basking material properly.
Certain stones, especially granite, really throw IR thermometers off if they aren't calibrated to them. We've had cases here where the temp was reading 130+ with an IR gun, but the true temperature as measured with a digital with probe was 105ish. A huge difference that is easily explained by the science of how an IR gun works.

In the basking area of my tank there are also spots that get up to 120. My dragon only uses those sporadically but still he does.
Whether or not 120 is too hot depends on your individual dragon. And probably tank size, in a huge tank you/he can get away with/from the hot spots way better.
But yes, the meassurement has to be on point.
