The Drop ASA OMNI was developed from the desire to create a drop down ASA for all. While extending as little as possible the markers and generating maximum compatibility. It consists of two parts and each part is machined from a solid block of 7075 aluminum and then finished to be extra durable. Optional adapters are available for the First Strike Scout and the Valken/Milsig M17 to make the Drop ASA OMNI look like it has always belonged. Before shipping, each product is tested by us for material, function and quality.
