Ran acros a UK dealer for Vepr and Sagia 12 gauges while looking for drums ... Odd thing I found ..
In the UK you can buy said 12 guage and even 20 rounds drums but the gun has to have a 24inc barrel ...
My fav is that you can buy a AK 103 a 101 all that fun stuff + silencers + drum mags .... But you can only have the rifle as a bolt action no semi autos unless 22lr
Very strange indeed Saiga-22 rifle
