Just got back my ak 47 from riley ,it was ripping factory brass cases [2 out of 95] but not steel cases , i was just going to roll with steel only but it failed badly my no go gauge . I notified riley and they said send it they will fix it for free ,this is a nj ban state ak bought by me in 2021 two + years out of warranty and had 500ish rounds through it . What i got back was my old furniture on a brand new weapon .........NO CHARGE NOT EVEN SHIPPING . It passed my gauge test and will get range tested soon . Bottom line is buy the damn gauges and use them
