New LAR-8

[ces777]

Ho,

Brand new shooter here and decided on urchasing the LAR-8 .308 by Rock River Arms.  Question though...when i went to clean it - it seemed liek the rifle had been shot many times before...it was very dirty and the spent brass deflector had noticable markings on it (after I oiled it).  There was also a few very minor scratches in random areas and the firing pin had a very small area near the back that looked singed..even afer cleaning. 

So - the question is...is that normal?  I figure it is from test firing maybe?
