I just purchased my first precision rifle, a Tikka T3X A1 Tac and found that the rail on the handguard is not perfectly level with the rail on the receiver. (The bubble on the handguard is touching one of boundary lines of the level while the receiver bubble is perfectly centered) Should I be concerned? I don't plan on mounting anything on the handguard except my GG&G Bipod which has cant adustment. Thank you in advance for your feedback
