Picking a night sight

I am keen to buy a frontmounted night sight for my .22-250 fox rifle. Is the new Pulsar F155 from Thomas Jacks any good?

The F155 forward-mounted night-vision scope from Pulsar, distributed by Thomas Jacks (www. thomasjacks.co.uk), is the new version of the DFA 75. Most nightvision sights are standalone (in other words, remove your optical scope and mount the night-vision sight instead). The F155 is an attachment that fits to the objective lens of your own scope and transforms it into a night-vision sight.

The older DFA 75 model had an off-set viewing, which was poor, while the F155 is a straight inline attachment so will not affect your rifle’s original zero nor parallax. You can therefore just attach and remove as you need via the bayonet fitment and spacers.

What you see is a black-and-white screen that is digitally enhanced for night use and further enhanced by an on-board infrared illuminator.

Your own scope’s reticle is superimposed on the screen, so the bullet goes where the cross-hairs lay if zeroed at that range as usual.

At £989, it is a cost-effective way to switch between day and night use for vermin and foxes alike.

I have used the F155 on .22 rimfires, .223 and .308 rifles and I have been happy with its performance out to 150 yards.

One thing to note is, as the power of your scope’s magnification is increased, so are the screen pixels, so 6-7x magnification should be your maximum. BP
