A mount assembly for attaching a firearm accessory to a muzzle of a firearm that promotes a more secure connection. The mounting assembly includes a front collar and a rear collar that are operable to clamp the mount assembly onto the muzzle. A detent ring mounted on the front collar yieldably biased by a spring against the rear collar to resist relative rotation of the front and rear collars. The mounting assembly is constructed so that the spring force applied by the spring does not continually increase as the front and rear collars move to clamp onto the muzzle. Detent springs used to yieldably hold the front and rear collars against relative rotation can be weaker than the main spring, which further reduces unwanted forces working against clamping of the mount assembly onto the muzzle. The mount assembly is also constructed to inhibit carbon lock.
