Mk. V sight question



Log in to see fewer ads
Only for the OWNERS of BSA Martini Mk. V Internationals.
I want to know if any of you other owners have differing sight set-ups on the Mk. V front sight. Specifically, the drilling and tapping of three holes for the long sight base encountered on the Mk. III International. It seems to be the standard on the ones I have and have seen. Does anyone have one of the long-blocks with the three holes they arent using?

Question

Was it sold through Al Freeland? It may have been setup for one of his Aristocrat front sight sets. They were more common on the Mark III. My Mk V is drilled & tapped for the PH 1 base.

Just what I've been looking for

Kurt, can you tell me why some of the Freeland plastic inserts have the knurled bushing, for want of a better word, rather then just being drilled? I have both types.

My MK V is the same as yours.

Tom

diopter

Knurled bushing is the diopter. It permits you to change size or color with any insert threaded for the bushing. Some shooters like the bushings appearance.

Could you provide a photo of what you are referencing, please?

I think he might be referring to the little knurled metal foresight apertures that screw into the Perspex disc - as compared to type which is a bevelled hole drilled direct into the Perspex and which is the type in common use these days.

I suspect that, back in the day, some shooters thought the metal screw-ins were more precise and/or robust than the simple bevelled hole.

Sandy,

In my experience a metal/plastic insert gives a more reliable sight picture in strong sunlight. Under these conditions a bevelled aperture can fail to produce a ring.

Centra make a modern version that is quite popular.

Vaver

Yeah, similar to the Vaver interchangeable inserts. I've never had a beveled insert fail to give a distinct ring. I'll have to play with them next time out. I generally use a yellow or green one.

Thanks for the replies. But we can wander off-topic fairly easily. One thing I wanted to know is if any of you happen to have one of the long front sight blocks that are on the Mk. III and the Mk. V.

Yea, I've got one but am reluctant to part with it cause I also have Freeland sights that use the base. Have you checked with Steve Earle?

I scrolled through his products and didn't see one there. Perhaps someone knows his site better can find one.

He is very "user friendly" . Talk to him and see what he has to say.

aperture

Sorry. It took a while to get back. This type of Freeland aperture screws in to the disc. It permits you change disc color. Some shooters believe the aperture is more distinct than just a bevel cut aperture. It was hard to get good pictures. I do have additional Freeland long front sight blocks. I have a couple of Freeland military front sights.

How about a photo of the Freeland military sight? I don't know what they look like.
