With the Velvet Revolution and the fall of communism in Czechoslovakia, a new Czech Republic immediately looked to NATO membership. This would require rearming the Czech Army with a rifle in 5.56mm NATO. After some unsuccessful dabbling with the Lada/CZ2000 AK platform, CZ began to develop the Bren S805, a modern AR-18 derivative designed by Ladislav Findorak. This was tested against the FN SCAR in 2009, and adopted formally in 2010. A few shortcomings of the design became apparent as rifles became widely issued, and CZ instituted an upgrade program for a second generation 805. This would eventually lead to the Bren 2, but today’s video will focus on just the differences between the first and second generations of the original 805.
