The NoMar Plate is an improvised receiver end plate for the AR15/M16 rifles. Our product is made from SAE 1008 cold rolled steel and is coated per mil spec 16232M (Manganese) and 16232Z (Zinc). We back our products 100% from any defect. ISO Certified Manufacturer.The NoMar Plate incorporates a new design feature that differs from previous improvised end plates. It utilizes two tabs that give extra protection to the receiver of the weapon. (Previous end plates allowed the connection point from the sling to the rifle to rub on the receiver when in use causing damage.) Its ambidextrous design not only allows any shooter, regardless of dominant hand, to utilize it once installed, but also allows both 1î and 1 1/4″ web straps and caribiner sling attachments to be used. The forward assist device is clear and usable by military standards. ItÍs so impressive that Stag Arms has decided to install the NoMar plate on all of their LE (Law Enforcement) Rifles.
