The AK is a Saiga .223 I converted myself, then found an old vented gas tube for. Also went with an RPB industries stock, found an old Russian bandage and TQ to put it in too. Then just a wood handguard and classic AK74 grip. And did a one piece front sight/gas block as well just because I wanted a nicer setup and the option to swap the muzzle device later on - and because I had to take the originals off to put on the handguard retainer anyway.
The medkit I just went on ebay:
Hope that helps!
