00041 here this should help. man that gun looks beat up in a close up. Its got around 3500 rounds through it now after 5 seasons of use. still shoots good but the barrel is starting ne cleaning more often and its getting picker with the loads. still will do under 1/2 groups, or least it did this spring the last time it was on paper( 900 ronds ago) every thing between the crudely cut away Saiga fore grip and the reciver is were the RSB attaches to the barrel.
