A type of muzzle loading firearm- catch is, you don't load it from the muzzle. The barrel is threaded onto the frame, and there is a wrench to unscrew it. With the barrel off the weapon, fill the chamber with powder, set a lead ball on top, then scew the barrel back on. While slow to reload, this design gave a very tight bullet-to-barrel fit, was very accurate and hard shooting. Link below is to a photo of a well made screw barrel pistol- you can see line where barrel unscrews.
injection molding screw barrel
A barrel nut is an internally threaded screw with a slotted head.
Loosen the screw on the forearm push up on the screw and the barrel will pull out
On the upper barrel, not including thread.
A Screw Barrel is primarily utilized in the plastic and rubber industry, specifically within extrusion and injection molding machines. It serves a critical role in these processes by facilitating the movement, melting, and mixing of materials. In extrusion machines, the screw barrel's primary function is to convey the plastic or rubber material from the hopper through the heated barrel. As the material moves forward, it is gradually melted by the friction and heat generated by the rotating screw and the external heating elements. The molten material is then pushed through a die to form continuous shapes, such as pipes, sheets, or profiles. In injection molding machines, the screw barrel operates similarly but with a distinct purpose. The screw rotates to melt and homogenize the plastic material, which is then injected into a mold to form discrete parts and components. The precision and efficiency of the screw barrel are crucial in ensuring the quality and consistency of the final products. The screw barrel's design and construction vary depending on the specific application and material being processed. It typically consists of a helical screw housed within a cylindrical barrel, both made from high-strength, wear-resistant materials to withstand the high pressures and temperatures involved in the extrusion and injection molding processes. In summary, the screw barrel is indispensable in the plastic and rubber manufacturing industries, playing a vital role in transforming raw materials into finished products through extrusion and injection molding processes.

No, it must be permanently attached, meaning welded, to count as part of the barrel length.

There may be a screw under the fore end. If so, remove it. If there is no screw, or once the screw is removed, the fore end should pull away from the barrel, at its front. It may take some effort and may be held in place by spring tension. Once it comes loose, the barrel can then be opened normally, and will dismount from the receiver pivot. To reassemble, set the barrel in place, set the fore end against the receiver, and snap it back up against the barrel. Then replace the screw if there is one.
All you must do is purchase an A5/X7 threaded flatline barrel and screw it in, becasue they have the same barrel threading. 98 threaded barrels will not work.
The round door on the side has to do with taking the barrel off. It holds the screw in the lower right hand corner stable. If you remove that screw the barrel comes off.
I drill a pilot hole the size of the 'barrel' of the screw. -I always use a combination drill bit for sinking screwheads. The first part of the bit is the diameter of the 'barrel' of the screw and the step, one inch higher is the size of that screw's head. (The barrel is the diameter inside threads) -I have a set of these drill bits for #6, #8, and #10 screws and they are great.
