AEA HP Barrel rifling.

Hi all

i have a AEA HP .30 Carbine and was wondering if any body else has looked at the rifling i cleaned mine and took a look down the barrel 

and it looks very strange you almost can’t see any rifling in the barrel kind of like my fx smooth twist barrels but way harder to see. If anyone can look at yours and confirm this is normal or not please let me know. 


Thanks Marco
