O rings for NV007 night vision scope

This is the O ring for the NV007+A only, not the unit itself !!!

The PARD night vision device is for illustration only, this sale is for the O ring only !

This is a pack of 3 O rings for the NV007 to bayonet tube, it helps keep the unit snug up against the bayonet fitting for a tight non wobble fitting, when fitting a new O ring to the unit please use a little oil to lightly lubricate ( prolongs the life of the O ring ), you will also want to make sure the new O ring goes under the small catch as this can cut the O ring when fitting the 007 to the bayonet if not done correctly !
