I've read somewhere that there are several variants of the 2A46 main gun, and the barrel length varies from L/48 (2A46) an L/55 (2A46M-4)... I want to build the T-90A in service with the Russian army, not the export version (T-90S/SA.) I heard that this export version uses a different version of the 125 mm gun than the T-90 in service in Russia, Is that true?... I want to know the length of the T-90A barrel. Another question: It seems like the thermal shroud in the most recent 2A46 versions has less retaining brackets than earlier versions, Is that correct? If yes, then I must replace the Miniarm T-90 barrel because it looks more like an early barrel (with a different muzzle) Thanks a lot in advance. Best regards.
