its still a work in progress but its 95% done,
oh its all metal with a working bolt,its not 100% accurate but its close enough.
i will post some more pics soon,and im building the crutch too! cheers reef.


Is that an available scope mount, or did you make it yourself? I’d like to know more about this.
While I get your point on rimfire vs center fire, in my experience people underestimate .22 magnum. The one I have will shoot a quarter size group at 100 yards with match grade ammo. That’s plenty good on human size heads at 200 yards. And making .22 magnum ammo in the way it’s described, with mercury fulminate that would explode on impact, is dead simple. Use a micro hand trusted drill, about .165 inches, drill into the hollow point. Put in the mercury fulminate. Then press a bb , .177 inches, into the hollow on top of it. On impact the bb will set off the mercury fulminate. Not it will not be as dramatic as the screen explosion, but would be enough to creat a larger wound channel I suspect since the amount in a primer can drive a .22 bullet the length of a rifle barrel.Not sure if he's still monitoring his thread, but I can tell you, I've never been able to find a commercial mount like it. The only ones I've seen have been made specifically for replica Jackal rifles, but the one in the movie looks well-used, meaning it might be a commercially-produced item. It only works on a scope with integral dovetails, which would be pretty uncommon today.
Several other points here: The prop ammo is akin to .22 Magnum, which would be totally inappropriate for this rifle. It's a rimfire cartridge, certainly not a target-grade round, and rimfires are not designed to be reloaded; they're designed to be cheap, throwaway brass. Loading one with a custom bullet would be difficult. The bullets shown in the close-up of his 6 special rounds are clearly dummies turned freehand from aluminum by a prop man, as they are all different lengths and shapes, which makes them useless for accuracy. The .22 Mags were likely used because they're readily available, and 99% of the viewing audience wouldn't know the difference. In real life, a centerfire cartridge would have been used, such as the excellent .22 Hornet or K-Hornet. I have several, and they would be ideal for this application. Lastly, non-gun people hearing the gunsmith talking about the exploding bullets as "mercury", are mis-interpreting this to mean pure, liquid mercury, which would in reality do nothing on impact. When he says "mercury", he's referring to fulminate of mercury, a very sensitive explosive formerly used in primers, which explodes on being struck. (Such primers were very corrosive on gun barrels, so they have been phased out in the West by non-corrosive primers.) The fulminate of mercury would be placed in the hollow nose of a hollow-point bullet, to explode on striking a solid surface.
There's an excellent and quite accurate replica from Japan on Youtube:
I'm not sure I'd consider making a functional explosive .22 using mercury fulminate to be "dead simple." Mercury fulminate is both heat and impact sensitive (two things that a bullet experiences during firing), meaning that chances are pretty high that the explosive bullet would just blow up in the barrel when it's fired. Then you get into the question of whether such a small amount of mercury fulminate would even make a difference if it could be fired and exploded upon impact with a target. I'd argue that the explosive potential would be so small that a shooter would get a similar or even better result with traditional bullet manufacture (wound channels related to the hydrodynamics of hollow points and frangibles).
In the end, this is pretty far afield from the prop aspect of the movie gun...it was a cool Hollywood concept that probably wouldn't work but that's why suspension of disbelief exists.
