@KuK137 Except Ian has done extensive videos on Polish resistance fire arms production. And they made sub machine guns. Not sniper rifles. Because making a simple blowback sub machine gun that will reasonably reliably hit at ranges a 9mm Parabellum can realistically do is a far cry from making a sniper rifle that can hit something so far away you need a scope the size of a roll of biscuits to see it. The Poles weren't idiots. They knew the limitation of their production means and produced firearms accordingly. They knew you can't produce to micrometer precision with determination alone, so they simply didn't bother.

@jw-hy5nq Those weren't 1 MOA rifles for sure. Most companies that make precision rifles cold forge the rifling by inserting a tungsten carbide rod with the correct profile into the bore and then crimp-hammer the blank around it so it has to be screwed out. Drilling and reaming a barrel blank to within a few micons is outside the capabilities of most shops that don't have ambient temperature control. Long-boring a rifling pattern into it afterwards, without screwing it up to the point it becomes essentially just a somewhat poor hunting rifle, is even harder. So that you knew a machinist who made ghetto rifles really doesn't tell anyone much until we see a 1000m grouping shot from a gun rest, as Hamas is claiming to be making sniper rifles. Not bullet hoses.

@FreebirthBoccara Nobody is doubting that they can use a lathe and a mill. But people who know firearms and machining are saying you can't make a sniper rifle with a lathe and a mill. You can make basic firearms, like a submachine gun, with a lathe and a mill. If it's a really good lathe and you have the right metrology accessories you can also make something like a combat rifle if you're determined enough. But a sniper rifle is just a whooooole other ball game. Remember that a sniper rifle is supposed to hit a head sized target at 1000m every time, all the time. A submachine gun is supposed to hit an upper torso sized target at 50 meters. And a combat rifle should do that at 300 meters. Tripling the distance while dividing the target by four is a very very tall order that requires incredible precision at every level of production. To the point where even well established rifle manufacturers produce everything BUT the barrel, and instead opt to source the barrel from specialist companies that only make those.

@markfryer9880 Nope. They bore, ream and cold forge. On the really supper over the top barrels they also do a cryogenic annealing run afterwards because even cold forging leaves a little bit of stress. Ian has an old video on it from maybe 1-3 years ago (I'm not good with time, sorry) where he visited a factory in Croatia that did their own barrels.

@MidnightatMidian I know. I did that with my H&K G3 (7.62) all the time with iron sights. But you can't do that with 5.56 or 5.45 if there is even the slightest whiff of wind, or if the rifle isn't extraordinarily good. And you'll not be able to do that with a factory new AK-74 no matter what. 20cm diameter grouping if both you and the rifle is above average. But in active combat any battle rifle that hits a torso target at 300m without fail is considered "working as intended".

@96dragonhunter The cold forged ones? Yes, they're absolutely rifled. The rifling is just not cut out of the barrel. The barrel is "smashed into the rifling". Think of the inside master as "a rifled anvil" that the barrel is "shrunk down on" with cold forging.
