Hey, new RFB owner here (who isn't really mechanically inclined), After (incorrectly?) reassembling my RFB carbine, it will not load live rounds, whether I pull the charging handle or press the bolt release. The charging handle will only go forward about an inch or so before stopping. If the gun is completely empty when working the handle or bolt release, the bolt goes forward just fine. Can someone please paint me a picture of what's wrong , so I can try to fix it without having to have it shipped back to KT? Thank you.
