Default New 03A4 Bolt

I picked up a new in wrap 1903A4 bolt from a forum member and it just showed up today. Looks great, still in cosmoline, and will go great in my future A4 build. One thing I wanted to ask about is the “C” stamp under the bolt handle by the “R”, as well as what looks like a “C” in the bolt sleeve recess. I had searched before and found pics of a couple bolts with the “C”, but no info.

Gotta day we have some great members around here!

OK, so what distinguishes it from a factory bolt? Are you saying it’s a clone? Please elaborate.

If it is a clone, it is the best looking clone I have seen. I think it is real. The only part that makes me hesitate is the cracks in the angled flat, looks like cavitations from welding. Machining is a little rougher than normal. The profile looks correct though.

Thanks for the feedback. I’ll get a couple other pics this evening of the handle marks and add them to the album; they don’t look like cracks to me, more like it got nicked by a tool, etc... I haven’t cleaned the cosmoline off yet so not sure if that’s making it look like the machining is rougher but side by side with a couple other Remington bolts it looks comparable.

I added an additional pic to show these marks a little better: https://www.flickr.com/photos/191021...57719035256054

Originals were cut in a fixture on a mill. Mill marks are clearly evident. Its a good clone possibly an Arsenal or a Benning rebuild bolt. The bend is good for a A4 but finish is poor. Could have been a Nam rebuild in country as we giving these tired guns to ARVN. My friend built lots of bolts for em in Nam in 3rd Shop. Did lotsa cut and crowns on 14s too early on too. Definitely was not cut in a mill.

I’m confused; you say the originals were milled, so are you saying mill marks are evident or should be but are not evident on my bolt? And in what way is the finish poor? I have one of your bolts I had originally bought for my A4 build; yours has marks running the length of the bolt handle, this A4 bolt has them across the handle. I’d expect this A4 bolt is the more accurate representation with regards to the machining marks.

I’ve uploaded a pic with both of these side by side so you can see what I’m referring to: https://www.flickr.com/photos/191021...7719035256054/

Not intending to be argumentative here, just looking for clarification. I’ve compared the bolt to pics of other A4 bolts out on this forum and milsurps and this bolt matches what I’ve seen, including the marks on the machines/milled portion of the handle.

Mine was finish sanded, the other looks nice but it was either sanded and buffed then refinished. The sweep on yours looks stock and will stick more out of stock horizontal. Looks parked so its not an original, they were blued from Remington. Couple indicators ot was a clone or a rebuild replacement bolt. I like it, hows it headspace?

Guys that shoot a bunch want them turned down more for more hand clearance by optic at top of stroke.

I'm good with the bolt handle sticking out further, and based on the profile from the rear in the rifle I'd expect it would clear my optics easily once I get the base on: https://www.flickr.com/photos/191021674@N02/51150707193

The bolt headspaces OK but I'd like to see more resistance on the Clymer no-go gauge. Still, I'm going to have a Criterion A4 barrel installed so it will be headspaced properly at that time.

Still not sure what you're referencing with the sanded/buffed/refinished opinion, but I put some new pics out in Flickr to hopefully illustrate once and for all that it's blued and not parked:

Anyways, as noted before I'm happy with the bolt and it works great with A3 receiver and A4 stock I'm going to be using it in. I know it's a little bit overkill putting in an A3 clone build but it didn't break the bank and looks fantastic.

Not passing judgement either way, here's a couple of extra A4 bolts I have laying around.

Pics are for reference.
