so ive been saving up gp for a new gun, and i was either gonna get a g36k or the tar21, both i know are really good guns if its used correctly, leave me your opinions, experiences, and comments and an overall rating of both guns. ty

Tar21 yo its kinda beast

Tar21 for awesome headshots

G36k has a cool scope while tar21 has awesome head shots >
