3G AK 25mm Lid Buckle
Duraflex 25mm Xlite Alula buckle - male part only
The female part is alloy (silver or black colour) and is attached to 25mm webbing loops on the lid. The male part (nylon) fits to the 20mm webbing straps. This buckle is on all AK rucksacks from post-2018 production.
Typically only the male part needs to be replaced, but female parts (which will need to be stitched onto the webbing loops on the lid) are available on request.
