the OSR isn't MADE to be overpowered
it's made to be the scoping sniper rifle that blockland for whatever reason was sorely lacking
also, i'm thinking of remaking the OSR into something new but still fairly similar: the "hunting rifle"
basically, you have a standard instant-hit but slightly spreaded shot without 'scoping' (in other words: looking through the ironsights) and a standard instant hit entirely accurate ironsighted shot
the downside to always being scoped is, of course, being more or less immobile. also, the shots never kill instantly: some shots do more damage then others, but it will always be a two-hit kill
