The Colt 6940, once a legal casualty of its monolithic upper receiver design, has returned to the market under CZ ownership. New CR-prefix models offer excellent reliability and performance, featuring an M16-cut bolt carrier and a free-floated barrel on a one-piece monolithic rail. While updated with Magpul sights and laser engraving, the core AR-15 platform remains top-tier, now at a more accessible price point.
This video provides a review and overview of the Steiner DBAL A3 dual laser aiming module, focusing on its IR capabilities for night vision use. The presenter highlights its robust construction, suitability for military service, and ease of IR laser sighting due to co-witnessed visible and IR lasers. Downsides such as a confusing switch, battery life, weight, cost, and form factor are also discussed. The review includes field testing with a Colt 6940, ATN PVS-7 night vision, and Team Wendy helmet, and compares the DBAL A3 to the Olight Baldr IR and Holosun LE221, with a personal preference for the Holosun.
