Rekieta Law discusses this ongoing topic in a video upload yesterday, "Boogie2988 Charged with Felony Assault - Criminal Defense Attorney Explains", 11 May 2021:

Rekieta argues (5:58 onwards) that Boogie won't get the maximum sentence for a Class D felony (six years), due to his lack of a criminal record; however, he suggests Boogie could be looking at over a year of prison.
Boogie could plead to "public disturbance" or "disorderly conduct", which involves a probation period (not being allowed to possess a firearm again, due to such a felony conviction being violent in nature; but possibly for other things, such as voting rights, the felony could be reduced to a misdemeanour after the probation period; Rekieta isn't 100% sure; he's a lawyer based in Minnesota, not Arkansas), including possibly even (much reduced) county jail (not state jail) time, with fines and community service also potentially being sentenced.
The self-defence argument is best used as "leverage" rather an argument in itself, as it is a weak one, considering Boogie did not even shoot Frank Hassle (who in turn did not present any particular threat for Boogie to fear for his life to use his weapon the way he did) and shot into the air instead; most likely the main reason why the DA have a hard-on for Boogs in the first place.
Tl;dr: the worst thing that could happen to Boogie is that he loses the right to bear a firearm.
