Pewpewpetie Posted September 18, 2019 Share Posted September 18, 2019 Hi all, currently wanting to dmr my specna arms sa-e14. I was thinking an m120 spring as local sights limit is 420fps on .2. do you think the box is strong enough or will other upgrades be nessasary? Many thanks Link to comment Share on other sites More sharing options...
