GPO | New England Custom Gun Service, Ltd.




The sporting optics market has featured an uncountable number of products, some poorly made and some of spectacular quality, sold by both unknown and well-established brands. However, over the last ten years of global production standardization and international sharing of technical expertise, the quality and optical excellence of premium European brands have become similar to those of many other brands. With regard to clarity and sharpness, the difference between mid-priced and high-priced products is indistinguishable to most customers. However, the pricing difference between these categories is dramatic.
GPO was founded by optical industry senior executives who have experienced how big brands increase profitability to support their massive production infrastructures. This corporate profitability structure normally results in increased consumer pricing or decreased product feature quality. We at GPO have a unique corporate structure that allows us to build higher-quality products with better features at similar prices or similar-quality products at better prices. Our products are built to our high-quality standards in some of the largest global production facilities in the world. All of our design, engineering, and quality management is done internally in Germany.
We at GPO strive to bring you the best premium product line at the absolute best price/value ratios in the industry. We offer a powerful industry Spectacular Lifetime WarrantyTM to consumers, and we publicly support select organizations that persistently fight to preserve your way of life. We will not invest in extreme infrastructures and force consumers to pay for it. We will not invest in making a product that gives you unnoticeably better performance for a disproportional increase in price. We will not mislead our customers. Our reputation from a lifetime in the sports optics industry ensures this.
When it comes to your next optical purchase, trust in GPO. You will not be disappointed.
