One of my favorite sci-fi takes on a modern weapon that I thought you might appreciate, the modified AK-47/AKM in the movie Elysium .
The modified AK-47/AKM takes inspiration from the XM-25 experimental airburst grenade launcher. It has a fictional attachment that combines a holosight, targeting laser, and rangefinder into an advanced targeting system. This targeting system links up with fictional airburst ammunition, programming the distance at which the round will detonate based on the range from the target. Each round has a kill radius of 5 meters, giving each about the equivalent explosive force of your average modern day 40mm grenade round. As demonstrated in the gif, this enables the modified AK-47/AKM to tear enemies apart, whether organic or robotic.
I’m not a huge fan of the AK, but this is perhaps one of my top favorite ballistic science fiction weapons, because it takes an already iconic rifle, and turns it into an absolute monster in an time setting where it is probably almost 200 years old, but without dramatically leaving the realm of realistic possibility in my opinion.
Such an interesting concept, and so easily overlooked during the film itself!
Fallschirmjägergewehr 42 automatic rifle - late war variant
Designed by Louis Stange c.1941-42 and manufactured by Heinrich Krieghoff c.1942-45 - serial number 02314. 7,92x57mm Mauser 20-round removable box magazine, gas operated select fire, bipod, ZF4 4x scope, spike bayonet, muzzle brake, 30mm Schießbecher grenade launcher. An automatic rifle designed to do everything and not weighing much for airborne troops, it somehow worked and inspired small arms development in the following decades.
Sawn-off Mosin-Nagant M91/30 rifle with SKS rifle grenade launcher, AK-series pistol grip and Burris red dot sight. 7,62x54mmR 5-round internal box magazine, bolt action. I’m ashamed to say it but I kind of like it, it’s like taking a modern compact gun and replacing everything modern with old wood and steel. Plus come on it’s a Mosin-Nagant who cares if it’s defaced, you can get 5 for 3 at Walmart.
