Deletion of SC-76 Thunderbolt

Comment: per . Particularly these two sources: https://nra.org.uk/wp-content/uploads/2017/04/2015Spring.pdf 1 (see the review on p. 10) https://mashable.com/2014/08/26/ukrainians-arm-themselves-in-preparation-for-battle/?europe=true 2 (see the extended quote from Simon Schofield - a defence expert). There's also some coverage of the appearance of the rifle at IDEAS 2014 but I'm not sure if that is based on a press-release or not. I've added these references and a couple of other ones to the article - take a look
