Recce rifles ,SPRs, and precision AR15s

Maybe something like a 16" SPR , i just dont know enough about selecting barrels or anything like that. Ive always shot bolties or did run and gun with carbines. Ive alwas geared my builds towards run and gun. Theres other question I just need to remember them.

I see certain companies match the bolt to the barrel, Whats the significance in doing that? Im assuming its accuracy but is it really effective or more of a gimmick?

No it works.
So when a batch of let’s say 158 steel bolts are made they are machined with in a tolerance between let’s say for argument sake .005+ or - .
If I chamber a barrel and match a bolt the tolerance would be more like .001+ or- . It’s not easy as pie to hit an exact number but with a little experience you can do it. If you go to tight on tolerance you can run into reliability issues if it gets dirty enough.
The looser the parts the more reliable in dirty conditions. The tighter the parts the more accurate.

Is this what you would consider lapping a bolt?

No, lapping a bolt your using liquid sand paper and smoothing out the high areas of the back of your bolt lugs and face of your action. This is used to better match the mating surfaces to improve contact area.
With the proper machining ” if that is an option” the surfaces will mate better to each other.
Not to say lapping is bad. It all depends on the situation.


The grit of the compound is also important for different jobs.
This is my attempt at a short answer
 I failed :smile:

Thank you! I know a little about alot and a lot about a little, Gunsmithing is not the thing I know a lot about LOL I can take most anything apart & put back together, inspect& recognize wear, damage etc. due to what I do for a living but knowledge and proper skill/ procedures of gunsmithing, I haven’t learned yet.

It’s life consuming and rabbit holes in side of rabbit holes sometimes.

Good info, thanks. Im debating going that route or not, I could always keep the current Colt bolt and hope the headspacing is correct or spend the bucks to get it matching.

Don’t worry to much about it. Just make sure what ever you do or end up going with just buy a go and no-go gauge. Checking head space is cheaper than a visit to the hospital.
If you are on a tight budget just buy a go gauge. You can use a .006 shim on top of the go gauge and now you have a no-go gauge.
Not recommending that, but in a pinch it will get you by.

I have some but that is good advice. I wouldnt mess around too much with an AR without being able to check headspace. Are melonite coatings on a ss barrel ,worth it?

3 Likes

Good question.
I don’t see it being a bad thing. Just another layer of protection. Remember melonite is just a surface hardener to the best of my knowledge.

So it wont effect accuracy like chrome lining does?
