The battle of Dummy GPNVG-18s continues as other airsoft blogs and websites review the dummies made by FMA and Spartan Airsoft. Austrian Airsoft website, Spartan AT, reviews both products and finds the Spartan Airsoft to be a much better dummy whilst the FMA version has its flaws, cannot be faulted much due to its price. So price versus functionality (you can see better through the Spartan Airsoft version)? You decide.
