Scope rails+scope rings questions

[Alpha1]

The Prototype.
I decided to use the original rear sight base and modify the rail to fit.
Mark 1:

It worked out OK I don't think Ill actually use this rail I will probably go with a longer one but this will do for a first attempt to get me away.
By using the original rear base it means I can revert back to the original sight if I want to.
I have prepped 50 lapua cases they will be dedicated to cast bullets shooting in the rifle.
Slugging the bore again is next now I have cleaned the barrel properly. I might post some pics showing sequence of events required to slug a bore we will see.

Alpha are you intending to drill and tap the front receiver ring to take your rail or are you intending to just cantilever it. If the later I think you will encounter a similar problem to the B-Square mounts no gunsmithing mounts on an Enfield i.e. it will act like a tuning fork and be totally inconsistent.

I'm intending to drill and tap the front barrel band. If I don't as you say the worry is it won't be rigid enough.

Barrel band- don't you mean receiver ring? Or have I misunderstood and you are mounting it scout style for an extended eye relief scope.

Sorry yes receiver ring. Not barrel band. I am making a start on Mark2 to night I won't drill the receiver until I'm happy I have got the set up right. Once it's drilled and tapped there is no going back. hmmm what's next.

A tip, once the barrelled receiver is in the vice of the mill for drilling do not remove it or move the axis until you have tapped the holes, I use a mandrel in the drill chuck that engages into a register in the top of the tap wrench to make sure everything is perfectly aligned.

[Alpha1]

That sounds like a good idea thanks for the tip.

Mark 2 is much better I'm getting there.
