The new spec EU-decoration guns do not have moving parts and you cannot dissasembly them anyhow. So e.g. no load through, no dry fire, no mag change etc. possible.
All deactivated original firearms, "EU Deco Guns", serve only display reasons,according the EU Regulation 2015/2403 Establising common guidelines on deactivation standards and techniques for ensuring that deactivated firearms are rendered irreversibly inoperable.
Each deco gun is stamp-marked according the EU regulation and each comes with an "EU demilisation certificate".
Новые правила ЕС требуют не только полной блокировки деактивированного оружия,но и специального клейма на нём,а так-же сертификата ЕС единого образца.
