The gun corresponding to the armor-piercing bullet in the national gunfight, please be more detailed, thank you.

Rifle armor-piercing bullets include eastern rifle armor-piercing bullets and western rifle armor-piercing bullets, ak and qbz95 in the east, m4a 1 and that 25-bullet rifle in the west. Shotguns, sniper rifles and submachine guns all use the corresponding types of guns, and then pistols are small and medium-sized and mail armor-piercing bullets (I have smoked some myself, just like medium-sized ones) to Glock 65433. That's about it. Please accept it. Thank you.
