What modification is found on the RPG-7 Iranian variant?

The Iranian variant of the RPG-7 features polymer furniture, which refers to the use of modern synthetic materials instead of traditional wood or metal. This modification improves durability and reduces weight, making the weapon easier to handle and carry. The use of polymer can also allow for better weather resistance and a more ergonomic design. This is particularly significant in military applications, where reliability and ease of use are critical factors. Polymer furniture can enhance the overall performance of the weapon and aligns with modern manufacturing trends in firearm design.
