Offset sights for prone

Post by stuann »

Any experiences or advice about how a right handed shooter can use left eye?
MEC has offsets - are they sturdy or does one have to be extra careful about handling?

They also have the MEC Swap, which appears to be a prism that allows you to keep the front sight in place, and even swap from one rifle to another.

Other options?

This comes up now and again, most recently at the link below.

Generally, if your only concern is eye dominance (e.g., you're a right-handed shooter who is left eye dominant), then a blinder over the eye you're not using is the preferred method. If you are unable to see well enough out of your right eye to shoot, then the various offset options are something to consider.

I suggest seriously looking at the models by Centra. They are well built and return to zero well

A club mate uses Centra outriggers to shoot right shoulder and aim with her left eye. As noted above the sets are removed for transport, and return to zero; the foresight outrigger attached like an extension tube and has a locating collar that stays on the barrel with a pin to index the outrigger.

I understand it was a little fiddly to set up, but once this was done, the set up doesn't appear to move or shake loose during use, but it is susceptible to damage/loss of zero if the rifle is knocked over.

An item of note, the starting post does not indicate if the user intends to use this system for smallbore or for a centerfire rifle. In my post above I assumed smallbore use. If using on a centerfire rifle I suggest contacting Doan Trevor. His system is a little more sturdy for centerfire use.

Hi
This is my first post.
I have a recent problem with my right eye and my averages had dropped significantly. I have just purhased and started using the MEC Swap crossover prism in order to use my left eye. This is an excellent device, although a bit of a fiddle to set up initially it can be done in position. Once the coupling device is fitted and adjusted the crossover bit can be easily removed for transport and fitted back on in exactly the same position every time. My averages are now back to my best and I would recommend this .

Do you find that the prism degrades the image somewhat, either in terms of sharpness or light admitted? This is what has been alleged about this device.

I do not think image quality is affected by the prism and I have not noticed a loss of light. One problem I did have is with eye relief and found that I had to bridge the breech of my KK300 Alutech with the sight riser block. I use Shooting Equipment 12.5mm blocks and this did the job. Have since done a little filing to make loading easier.

Any chance you can attach a photo of how you have set it up, im having chronic problems with eye relief after installing this?

Thanks
