my homebrew add on mk1.0 - zeroed and christened!

Post by jax13 » 26 May 2013, 22:01

I set myself a few simple requirements for this build. the criteria was pretty simple... sub £100 build, interchangeable onto any scope, 50 - 100 yard shootable vision plus extra spotting distance as a bonus as verified by a brace of 80 yard bunnies this evening

I looked at a fair few builds and took the ideas i liked to develop my own system which is still in a mock-up phase as i need to alter my board cam / project box mounting method.

In my opinion, the rail is better side mounted rather than top mounted as it is less likely to sag and also puts it further away from the head.

the monitor mount was a stolen idea - the lower half of a weaver mount screwed through the base of the stand (which has then been dremmel'd down flush with the mount to tidy it up) allows it to be clamped to the side of the lamp mount off to the side of the rifle which for me is a lot more comfortable as you can shoulder the rifle properly and simply open both eyes rather than a mounting position on top of the rail where i kept lifting my head to look at it. (what i didnt want to do was start altering the way i shoot / mount the gun and risk picking up bad habits for shooting 'normally')

As said, this is still a mock-up so there are longer cables than the finished version will have & things need to be refined slightly and tidied up around the project box (i will use a slightly larger project box in the finished version to give me space to tidy the cable routing). pics follow followed by a build list.

the important thing with this style of setup is to make sure you use matching mounts to put the camera into and mount the rail to the scope as this should (if your camera is mounted centrally and the rail isnt bent / sagging) put your scope picture pretty much central on your screen and have it looking down the scope straight on rather than off centre or at an angle.

Is that a .22?
Also if you put a bracket on the stock you could mount the camera on that an remove the rail altogether. And to be fair they don't sag. I have a heavy gen 3 mounted similarly on mine across the top.

But a good job all the same.

nice progress Jax, :thumbup:

have you thought about putting a loupe on the screen and move it closer, which will give you your normal eye relief and stop some of the light spill from the screen http://nightvisionforumuk.com/viewtopic ... +of+set+up

whats the rifle?

It's a. 22 walther target action, 1" thick stainless target barrel (hence the bloody awful tape) and an old 'keef' fully adjustable ally stock that was made for my old rapid 7. I needed to attack it in a couple of places to make the action fit but it's nice and snug and awesome ford shooting off sticks.

There is a he'll of a lot of weight in it but it gets used for static shooting rather than wandering because it is dead bunny accurate to 100 plus yards.

It would make a cz action bend in the middle it's that bloody heavy! I did think about getting it turned down a bit or tapered but I kinda like the fact it's the same diameter as the ph mod that is screwed onto the end!

Nothing at the moment! It was originally going to be an 18650 torch with a oslon drop in but they never arrived (China shipped ebay buy) but marky610 is kindly sending me one of his spare units to use while I wait for the replacements to get here by boat.

Nice set up. I like the idea of the weaver rail at the side. Are you going to attache the illuminator on the side rail as well. Good job

Illuminator at or will be above the scope on a fig8 mount (the one the screen is hanging off the side of at the mo)


It all seems very natural when shouldered despite it still feeling a bit wrong not looking down a scope tube. I find there is a massive temptation to lift my head off the stock but it is makes everything seem shaky as I obviously clamp the rifle between my hands and cheek to get a stable shot.

I will more than likely be dropping this scope and nv rig onto my multishot bolt rather than the single shot as loading is a bit fiddly with the extra bits hanging off the scope (and with the bolt being on the wrong side for me) the other benefit of swapping it to my savage is that it is designed with a bit more mobility in mind (sling, bipod and lower weight for carrying) leaving me with this one for the long range daytime sniping and the other one becoming the sneaky option!
