Parker Hale Target sights for FN FAL and SLR

[Peter Laidler]

Ready for a bit of mathematics everyone......? If there was, say, a .010" deflection left and right of the TMH on the body - and there would undoubtedly by a great deal more, even on new production believe me - then just multiply that possible deviation in the form of accumulative error left and right out to a range of 200 yards onwards. Naturally after a few rounds of steady shooting the rifle settles down into the shoulder following recoil and the following reciprocation of the working parts. It's what's called 'settling' or 'normalisation' for obvious reasons*. You can get the feel of it when it assumes its seemingly natural firing feel....., difficult to explain in detail. But then you get up and move - so does the body against the TMH no matter how or do a 100 yard rundown to the falling plates and then..........

There were all sorts of methods of tightening up from inserts, spreading the body a tad, ring punching the axis mech to spring loaded ball bearings and........... But the rifle will just do what recoil and the action tells it to do.
*that's why we always fired a few rounds into the bank prior to range and accuracy testing and where possible always fired from the layer

As for the hole size, that's all very well on a nice manicured range at Tidworth but in the dark or half light in the eerie bush, the bigger the hole you've got, the better if you'll excuse the phrase
