AJ Parker M80 sight

[Calfed]

Recently saw a reference to an A J Parker M80 sight for Enfields. I can find no information about this sight.

Anyone able to fill me in?

Thanks

The A.J. Parker TZ 4/80 was an updated version of the TZ 4/47 for the Lee-Enfield No. 4. It was the last of the TZ line.
I presume that is the sight you are referrring to.

No thise was definitely a "twin zero M80". It might be the same item, but the nomenclature was definitely "M80"

This is a picture of the "Twin Zero M80".

The TZ 4/80 moved to a scale calibrated to 7.62mm NATO (144gn ball); most of the TZ 4/47s still had a .303 scale. In practice, target shooters mostly used the minutes adjustment and didn't use the range scales at all.

I think the M80 is actually the modular 7.62mm sight that fits on a range of adaptor plates for different actions - the equivalent of the PH5E4 sight.

I think the AJP TZ 4/80 also has 1/4 minute adjustment as compared to the 4/47 which has 1/2 minute adjustment.

Nothing so simple!

I've got 4/47 (303 scale) in both 1/2 and 1/4 minute, 4/47 (762 scale) in 1/4 minute scale, and a couple of 4/80 in 1/4 minutes.

Some of the above are in their original boxes; they just have "1/2 minute" or "1/4 minute" written on the label.

I have no idea why AJP and PH competed to see how many different sights they could get under one model number - I must have about ten different types of "PH5C", as well as "PH5CD" and "PH5D" sights that are still identical to other PH5C models...

If any ones got Edna Parkers book "A century of Sights & Sighting Aids" the M80 is on page 39

It is described as the "1980s model sight that will adapt to numerous actions & brackets"
