| I received a 603 upper and I just noticed I have a rebated recess.I recall a detent pin with a ball bearing is needed for those correct??.I am finding the "little"things go right by ya in a hurry.......who has those pins..I see offset pins and slotted pins but apparently my search fu is "offset" |
| Dings,Bro,,the rebated lug ONLY uses the 601 pin on a 601 and 602 with a slabside lowerAll upper receivers were rebated up to about 1969 + -,colt just never changed the forging.You cannot use the 601/602 pivot pin as the correct lower for a 603 is either partial fence,or full fence and uses the standard pivot pin and detent.The 601 pin has a full round head and will not even fit on a partial or full fence. |

thank ya gentlemen.I felt some rattle and space between the upper and lower and went through everything and noticed the rebate..thanks again
receiver is a full fence.FWIW.Things start to come back slowly as time has erased a lot of things I should know or took for granted. |
