The news that ACM was to produce a replica of the Kobra sight was greeted with much excitement by those airsofters who like to re-create Russian themed kit loadouts. While there is a huge amount and variety of Western red dot sighting systems available to the airsofter, until ACM announcement their replica there was no Russian red dot available at all - unless you were able to afford a real Kobra sight (which would set you back anywhere between £150 to £200).
