[Star Wars] What if I have a M4A1

Just say I am in Star Wars universe and I have a M4A1 assault rifle.
How effective this weapon will be against a clone trooper, a normal roger roger droid, and a well-trained force sensitive user.

I assume M4 will be pretty powerful against all of them. For example in Revenge of the Sith. Multiple jedi cannot stand huge amout a gun fire at once. M4 can fire at least 700 round per min. and since my bullet is not in an energy form, lightsaber can melt, but cannot ricochets. Please correct me if I am wrong.

Jedi would be moderately screwed. Keep in mind that bullets are likely more vulnerable to telekinesis, but ultimately, in-universe kinetics are the weapon of choice when kitting out for Jedi-hunting. The molten bullet would still be going towards the Jedi.

The reason nobody uses them is because they are horrendously outmatched by blasters. Your puny slugthrower will not even scratch the paint on the plasteel armour of a stormtrooper; your average blaster can tear out major chunks of walls, even nearby blasts kills unprotected rebels, and heavier blast rifles can split a stromtrooper in two. A blaster bolt is closer to a small autocannon round in terms of raw destructive power. Old fluff claims Starfighter cannons output *kilotons per each shot*.
