Rockola..the good , the bad..the ugly.
Where to start...the bad? It is a 'Blue Sky". The barrel is Underwood 6-44 and looks real good inside.. FCG is upside down Inland logo, hammer is KR. Op slide is underlined PI with numbers 184813 on out side.. Bolt is flat IO. Bayo lug/swivel marked JM. M marked mag catch, flip safety. Recoil block marked RO-G. It was tagged Underwood but the R and A peeking out from under the milled IRCO rear sight told me other wise. The SN# 1758853 on receiver. Some shops don't pay much attention to the info under that rear sight.The good...it is in good order, the finish is consistent on all metal parts and the price was not too bad...$500 OTD down from $650. The UGLY...a synthetic stock with pistol grip and perforated metal hand guard. I have a decent GI stock and hand guard and can unload the synthetic stock to someone else. I would post pics but it is just to gruesome to behold.
Keep the metal handguard...
and weld to it a 6" long piece of 5/8"W X 3/15 CRS to it.
THen use a Weaver 336 scope mount to locate the holes for drilling & tapping a Scout scope mount.
Did this to mine when the youngest asked to go Deer hunting; (daughter, 100# 5'5") I was back-up with .308.
old K1.5 Weaver looks nice up there, eject fine, no problems.
