The advanced combat optical gunsight, or ACOG, is valued by soldiers the world over. It’s a rugged, tough, small design that makes it perfect for combat at a wide variety of ranges. There are a range of clones on the market, and their quality ranges from absolute trash to close to the nigh-legendary sight by soldiers the world over.
AR-15 “pistols,” or short-barreled rifles (SBRs), are extremely popular these days due to their ultra-compact size, high-magazine capacity and .223/5.56 rifle-caliber chambering.
