The poor man's version of the CorneShot, EB Airsoft now have in stock a replica of the Accutact AngleSight made by Element. This will help you peek around corners without exposing you much from the OPFOR. This can be mated espedially with Holo Sights such as the EOTech ones. Pricing is at US$29.95, free shipping included so better grab yourself one before it runs out of stock since this is a cool tactical accessory.
