Hey RM, happen to have a list of Russian sneak serials? I know you were keeping track of the recent imports on another forum. But just wondering.
Buying this has obviously sparked my interest
Here's what I've got (unfortunately with these sneaks, I didn't take date information, so it's just a list of S/Ns):
IO Monroe: (AO5188_И) (AT458) (AП919) (AГ4662) (BK478) (BM1066_И*) (CM4150_K*) (HE2007) (НГ2647) (HП1385*) (HП1708) (KA2951*) (KA4675_ Д) (KO1385) (KN1385) (KP2180) (KП1385*) (KП1708) (КП1950) (KП3123) (KП3627) KГ5468 (КЮ4129) (MB3789*) (MC2266) (MП5375) (O2642_P*) (O2960_P) (OK2110) (OЮ617) (OП8597) (PB1921) (PB3591) (PM9030) (PT4161) (PП1454) (PЛ4493) (PИ1578) (PЛ7360) (TИ4214_K) (TP7810_Д)
(ИM349) ЛТ4949* (ЛП3425) (ПA836) (ПA2277) (ПH298) (ФA1236) (ФЛ140) (ФП3879) (УM2571_K*) (УM2152) (ЗЮ1731*) (ЮП3243)
TGI: (AT1733_И* force matched '49 cover) CA2957 MT2782
IO Palm Bay: (HT1873) (KB2495*) (KГ4934) (KP6198) (KЮ1101) (ОП1415) (OЛ5219) (OЮ1495*) (РП5165) (PИ1578) (РИ3881) (PЛ7486) (ПO1257) (ЛM4202_И) (УA7687_И*) (УM6786_K)
Yours looks to be either a HГ (seen in IO Monroe) or a KГ (seen in Monroe and Palm Bay) prefix. Neither set is a letter gun prefix, so it stands to reason yours isn't either (and the 45° gas block kind of verifies that anyhow).
Either way, I'm thinking you're going to be pretty happy with it. Would be awesome if it came with a matching receiver cover...but I think the odds are stacked against you, otherwise the seller would have indicated a year on it. Something like this...
