NOTE: WR do NOT recommend using the integrated nut method on many brakes is nice and convenient, but due to rigidity and an massive increase in modulus of elasticity.BRAKE FITTING EXAMPLESVarmint barrel with jam nut.Lightweight barrel with jam nut.Using an O-ring, which has some proven harmonic advantages...The O-ring idea pinched up (only).
