Ive got a 10 gal tank that has been running for quite some time now with little to no issues. According to water tests it seems to be cycled. I normally get .25ppm for ammonia but that seems to be where my kit zeros out, 0 nitrite, and about 20ppm nitrate. I still run water tests quite regularly to make sure everything is all good. On occasion I get a reading for ammonia of .5, which in actuality is .25, 0 for nitrite and still around 20 for nitrate. Is it normal to get a reading for ammonia? or is there something off with my cycle?

Just to clarify what you mean by running for quite some time, is it a tank you are/have just cycled?

When do you notice the rise in ammonia? If your testing after a water change it could be the water you are adding.

I used the same tank, rocks, and media for about 4 months, Lost my stock due to a power outage...
The tank sat full and running without any stock for about 7 months after that. I recently added 4 tiger barbs ( which are in the process of getting put into a bigger tank) that have been in for around a month. I feed a mixed diet every other day, and usually the day after feeding I get the reading, after that I usually do a water change. For some reason I was under the impression that you shouldn't get any ammonia reading in a cycled tank

Low range is too low? How low? 6?
If your pH is low, you are just reading ammonium, not ammonia. Ammonium isn't as harmful (maybe even harmless).

I mean as low range doesn't read high enough. It always yields it's highest value
