Sup folks?  It's been a few years since I was a frequent flyer in the retro forum and I'm a tad out of the game.  I came across these in the bottom of my old parts drawer and just can't remember the finer details of the early bolts.  Is this BCG proper for a 601 build or a early 602 build?  Thanks in advance.

I'm not an expert, but it looks correct to me for a 601.  Has the straight key.

My vote is 601 by the P marked bolt

Early narrow band P bolt, round key, round stakes, +1 for 601.

The bolt is correct for a late 601 or 602.  Change out the extractor with a square edge instead of the angled edge style, and the bolt would be correct for an early 601

I found the same BCG with a parked bolt head assembly recently at a gun show.  It lives in my transferable SP1 now with a nickel-boron bolt head.  It’s the easiest BCG to clean that I’ve ever owned.  I tested it with some Wolf steel case and I love it!  Well worth the $100 total investment I have into it!!
Good find!
