How a Kar98k Works

How a Kar98k Works Lifting the bolt forces the 'cocking piece'  to the rear, partially cocking the action. The cocking piece rides along a  ramp in the bolt, forcing it back. A cross section shows the compression of  the 'firing pin spring' when lifting the bolt. The bolt is pulled to the rear to load  the ammunition. Cartridges can be loaded individually or five at a time using a stripper clip. The clip is ejected when the bolt is closed. Pressing the bolt forward strips the top cartridge,  which is directed into the chamber under the control of the extractor. Closing the bolt locks the two front locking lugs into the receiver. The 'sear' keeps the cocking piece held back as  the bolt is closed, fully cocking the action. The Kar98k is equipped with a 'two-stage trigger'. Initial trigger pull provides resistance and slightly lowers the sear. This feature cues the shooter to imminent firing and permits a crisper release of the striker.   Continued trigger pull engages the second lobe of the trigger, fully disengaging the sear. This releases the firing  pin, causing it to strike the cartridge primer. The expanding gases from the powder  charge propel the bullet through the barrel. The 'extractor' grips the rim of the spent  cartridge case. Lifting and pulling back the bolt extracts the case from the chamber. As the bolt travels to the rear, a spring inside the bolt stop pushes the 'ejector' inward, forcing the case out of the rifle as it makes contact. The 'bolt stop' engages the left bolt lug, preventing  it from coming out of the rifle upon extraction. Pulling outward on the bolt stop, allows the  bolt to be removed for cleaning and maintenance. The Kar98k uses a 'safety' to prevent the rifle from firing. In the left position, the safety is off to fully permit firing. In the up position, the striker is prevented from moving forward. The bolt however can still be opened and removed.  In the right position, an extension of the safety fits into a notch on the bolt, locking it closed. The striker remains blocked in this position. Housed within the bolt sleeve, is a 'lock plunger'. As the bolt is opened and pulled to the rear, the plunger engages the safety notch on the bolt, preventing the bolt sleeve from  rotating during manipulation.

This reminds me so much of like mid-late 2000's History channel.

I have one of these Mausers and the animation is spot on, how did you do your research?

[u/EjPetersondotcom]

This is the kind of stuff I used to watch The History channel for. Outstanding work!

Still don’t understand how a human could’ve engineered so many features into such a small thing. Insanely well done explaining all of it so concisely

This is really incredible, great work. I don't know much of anything about guns but it's really cool to see all of the clever mechanisms involved in each feature. I wouldn't have been able to understand this without a lot of effort otherwise. Thank you for spending all of that time collecting and digesting information so others can appreciate these devices!

I know absolutely nothing about guns, but this made the innerworkings of the magic shooty tubes that much clearer for me. Fantastic animation, very professionally done!

PS: I was reminded of a similar AK-47 innerworkings video, went to rewatch it, and wasn’t surprised in the least to find out it was from the same person. High-quality stuff.

1 - Is this your voice?

2 - how long does something like this take to make?

I hope this video gets tons of views! Well done!

Do you think that there is an overlap between these types of animations and actually 3D designing of weapons, or they are two different things?
