AccuCover
« on: December 19, 2011, 02:09:22 PM »
The AccuCover is an aiming and accuracy enhancement device that fits the rear ocular eyebell of the scope, much the same as many other flip-up type scope covers. It has a rubberised body tube, moulded onto a hinged plastic collar, to which the cover itself is fitted. The hinge is spring loaded, so on operating the opening button, the cover automatically moves out of your line of sight, giving an unobstructed view through the scope.

I was very kindly sent one of these covers a few months ago to review, unfortunately, due to unusually prolonged and high local wind, (and other circumstances) I have not been able to test the AccuCover as thoroughly as I would have wished, but I hope that what experience I have had with it, will be of interest and benefit to you all.

"Nothing much different to other covers there then" you may say, but what marks the AccuCover out as unique is the inclusion of four small fluorescent yellow/green aiming arrows on the internal rim of the cover, in the 3, 6, 9, and 12 o'clock positions. These are to be precisely aligned with the scopes cross-hairs when fitting the cover, and then aligned with the ends of the cross-hairs again, by centralising your eye in relation to the scope when taking a shot. The whole point of it is that it helps to eliminate scope cant and parallax error, and introduces consistency into your aiming technique, and as is well known and accepted, one of the biggest keys to achieving accurate shooting is consistency.

The AccuCover comes smartly presented in a clear blister pack with a colourful card insert that shows the size of the contents and tells of the benefits of the product. I had thought that there werenít any instructions included, but upon opening the pack I discovered that the card insert opens up to reveal the instructions, and other information inside.

Three sizes are available, the E3538 which fits scopes with an eyebell diameter of between 35-38mm, the E3841 which fits eyebells between 38-41mm, and the E4144 which fits 41-44mm diameter eyebells. Each different size has a different coloured opening button, blue for the smallest, red for the medium, and green for the largest size, so it is easy to see at a glance which size you have without measuring, especially handy if you swapped over covers from gun to gun.
After checking the scopes that I personally own, I found that the largest AccuCover, the E4144, would fit nearly all of my scopes, but a very small percentage of them would require the medium size. One or two of my scopes were only just able to accommodate the largest size AccuCover, but none of them required the smallest size.

On the sample I was sent, the cover would sometimes not open automatically when the button was pressed, due to a very small piece of rubber flashing impeding the cover from springing open. A few seconds trimming with a craft blade removed the tiny obstructing bit of rubber, and everything then worked perfectly.

One feature that I really like is the ability to be able the push the cover fully forward, so it lays flat and parallel against the scope, rather than sticking up out at 90 degrees to it. This then stops it from fouling on your cap peak or hat brim, or snagging on foliage, something which can be very annoying and distracting when using other certain makes of covers.

Another thing I noticed when trying the AccuCover on different Rifle/scope combinations was that if the scope had been zeroed using up a lot of turret adjustment (so the internal erector tube was not optically centralised) then the Accucover forced you to look directly down the centre of the scope, sometimes where the image was not at itís best.

Without the AccuCover you tended to slightly adjust your eye position to find the best image, but doing that with the cover fitted sometimes produced a slight less than sharp sight picture so you were caught between the devil and the deep blue sea, good sight picture, but not looking directly down the centre of the scope or look centrally, but with a slightly blurred image.

This anomaly cannot in any way be pointed toward the AccuCover, blame in that instance has to go to a poorly set-up rifle/mount/scope arrangement but the AccuCover does tend to highlight any shortcomings in that area.

So how does it fair when it actually counts, when shooting? Very well, Iíd say, especially in certain situations, please allow me to explain.

If you have a parallax adjustable scope, set to say, 40 yards, and you were shooting at a distance of 40 yards, then the scope would have already done the job of removing parallax error for you, and so the AccuCover would be of little benefit.

However if you don't have a parallax adjustable scope, or were shooting at a distance other than which the parallax was set to, then the AccuCover comes into itís own.

I had one for a while but one problem i did find was that the button that operates the flip up got lost whilst out in the field. I emailed accucover and they sent me a whole new accucover which was great but a few weeks later i lost the button to that one as well. problem was the way i carry the rifle when stalking the button was rubbing against my coat so thats how it fell off i rekon.

After using the Accucover on my 310 for many months now, I have to say that I would prefer if the button was on the other (R/H) side.

As I'm righthanded, my lefthand holds the forend, while my righthand is removed from the grip to operate the bolt-handle, and open the cover.

Obviously the bolt handle is on the righthand side of the gun, but the Accucover button is on the left.....so I feel it a bit awkward to have to stretch over to the left side with my right hand......if the button was on the right it would be Soooo much more convenient and userfriendly.

I too bought an AccuCover but found i spent most of my time trying to line up the arrows with the crosshair rather than actually shooting at my intended target which usually ended with me drawing a blank, so I removed it in favour of using an average PA setting of say 30mtrs...

Now one day whilst sat at work watching the rain poor down "AGAIN" and generally being bored S******S i had a brainwave, why not "etch" a dot in the centre of the rear lens that way all you have to do is position the dot on the central crosshair and "HEY PRESTOW" you'll be looking directly down the centre of the scope every time you line up for the shot, in this age of high tech machinery and gadgets this should'nt be to much of a problem for the lens manufacturers to do and if it was small enough so as not to obscure your target and highlighted in white, red or orange or some equivelent it will stand out against the black of the crosshair !!!  :D

What does anyone else think about my suggestion ?

I think that's a cracking idea Torny....the simplest solutions are usually the best!! 8)

I would suggest a tiny dot of Tipex, rather than etching the lens first off (at least while the idea is being tested), as the Tipex could then be fully removed leaving no mark of the lens if it doesn't work as anticipated.

A member of our club cuts out a bit of card the sane size as the rear lens and makes a small hole in the center then fits that to the rear lens
