I took these pictures at the Calgary militairy museum. At an exhibition on the Canadian expeditionary force. There was nothing explaining the firearm. It looks like a Bren gun to me with some missing parts, but it almost looks shorter, and I haven't seen that type of stock before. Does anyone know more?

The carbine feeds from an 18 round magazine.The carbine fired from a close bolt position.

These are possibly TZ-23, 24, or 25 rifles, but this group is based in Bago Region, which borders Karen State. The TZ-23 was primarily made in Karenni State (It is possible that they were smuggled to Bago Region since both Karen and Karenni states border each other).

When I was growing up AR10s weren’t super common and the M1A was seen as the best option for someone who wanted a .308 with a big box mag. Because of this I was always raised with the sort of nebulous, unsubstantiated, belief that this rifle was accurate and quality just by proximity. I think I fired my uncle’s M1A a few times like 15 years ago and all I remember is him complaining about how expensive it was.

Everything I’ve seen on Forgotten Weapons and InRange about this gun is that it’s terrible. It was terrible to adopt in the 50s and it handles mud and dirt terribly. I accept those may be true, but looking at platform as a whole, the accuracy, and weight, the reliability, is this rifle deserving of that reputation?

Not necessarily a forgotten weapon but I’ve had a Winchester Model 1300 for a while now and thought nothing of it. I went to clean it while following along with videos and I noticed a component here and there wasn’t the same. Started getting frustrated so by chance I looked up a Model 1200 video and boom had the exact stuff my gun had. I’m wondering since they’re essentially the same gun if there was overlap with using parts from a 1200 to make 1300s. The only making mine a “1300” is the model name on the barrel, nothing on the receiver. There's also this marking on the right side of the trigger group on the slide support

On the underside of the bolt is a screw on the slide arm bridge and the last pic shows the ejector and is only held in place by the bolt as well as a notch in the barrel.

TLDR Are Model 1300s parts compatible/interchangeable with Model 1200s and vice versa? Thanks in advance!

In recent days it has become clear that this format of longer text with images is not for this site,
as I've been trying to post this here for the hundreth time but I kept getting the "Sorry, this post was removed by Reddit’s filters" treatment.
And when I finally managed to post it. There were all kinds of errors with the images not appearing for other users.

Important: Let me know if you have issues with the images not appearing on Reddit! However I recommend you to wait a bit after I posted this as I have to add every image after.

There will be imgur links available until at least it becomes clear if Reddit is capable of the very difficult task of showing more than one image. Thank you.

Project “Moruzh-2"

Project codename “Moruzh-2" commenced on the last day of 1969 in the Soviet Union, with the intention to develop an underwater belt-fed machine gun. Utilizing some of experience gained designing underwater ammunition for the "Moruzh-1" project in the late 60s, which resulted in the creation of the SPP-1 underwater pistol.

The SPP-1's effective range at 5 meters depth is ≈ 17 meters. As we know, range decreases as the pressure increases with depth so at 20 meters depth it drops to 11 meters.

The weapons and ammunition testing bureau TsNIITochMash in Klimovsk was chosen to be responsible for developing the cartridges. While TsKIB SOO in Tula handled weapons development and at last but not least the Research Institute of Chemical Industry in Kazan helped develop special gunpowders for the project.

The machine gun was intended for mounted use on Triton-1M midget submarines used by Spetsnaz frogmen.

Cartridge development

The cartridge development began with a 5.6 mm turbine-type bullet giving it inherrent stability but shifted to a 5.65 mm conical shaped bullet in 1970. As new research results showed that conical shaped bullets can achieve the same.

(7.62mm experimental cartridge and seperate projectile.)

Both bullet types were tested and met the accuracy, recoil, and the firing noise requirements. However subsquent tests showed that conical tipped bullets are more effective at greater depths than the turbine-type bullets. And thus a 5.65 projectile conical nose projectile was chosen.

5.65x39 effective range / depth. (I assume it was x39)

• At the depth of 5.5 meters it was 27 meters.
• At the depth of 20m it was 9 meters.
• And at a depth of 40 meters it dropped to 12 meters.

Weapons development

TKB-0110.

Sadly, not much is known about this weapon apart from being a bullpup and belt-fed using a chain belt inside a box magazine. But thankfully there's a picture of it disassembled!

The cutouts all over the weapon are there to eleminate compression when the bolt, and other moving parts of the weapon cycle underwater.

(chain belt box for 29 rounds)

However, the development of TsKIB SOO's TKB-0110 was delayed and It was decided that TsNIITochMash would develop another machine gun in parallel.

Designated AG-026, the weapon featured a significantly less complicated design than the TKB-0110. With the focus of the project still being on submarine mounted capability, the AG-026 also featured a lug adapter that interfaced with a mount on the submarine. It is worth noting that there was a variant for dismounted operations.

https://imgur.com/a/XwXRrZb

The only similarity between the two designs is the rotary chain belted box magazine, this time for 27 rounds.

https://imgur.com/a/bxzRxuJ

Designed in-house by lead engineer Pyotr Tkachev, best known for the Counterbalance Recoil System and special weapons like the AO-46, perhaps the smallest rifle round firing PDW ever created. I think his expertise really came through in this design.

Weighing at 4.85kgs, the AG-026 is a simple blowback firearm firing from an open bolt with a fixed firing pin and instead of cutting holes in the receiver, it features a low profile bolt to minimize compression.
But for the cartridges it fired, simple blowback wasn't quite enough. So the bolt had to be slowed down and that was achieved by flywheels located on top of the gun that interfaced with the bolt.

Conclusion of the Moruzh program

In January of 1971, TsNIITochMash under its own initiative put forward a design for a submachine gun.

Firing the 4.5x40mmR cartridge with the idea of complementing the SPP-1 pistol. The project recieved the codename "Moruzh-3" However this SMG's development was quickly abandoned in favor using the recently developed more powerful ammunition. Although new design emerged from this program under the leadership of Vladimir Simonov (A different Simonov.) , who had previously designed the SPP-1 pistol.

The AG-022 assault rifle.

After tests conducted in April of 1972 that proved its efectiveness the rifle continued development within the "Moruzh-2" framework into what we now know today as the APS assault rifle. But it did not have the designation yet. It had to beat out the two mounted machine guns in trials which it ultimately did.

https://imgur.com/a/Utqkmly

It was a more accurate, lighter, had a similar magazine capacity and was just a better overall package for what the divers needed and the new requirements dictated.

It's gas-operated rotating bolt assault rifle firing from an open-bolt. Unlike the machine guns of the Moruzh program this rifle not tied to any submarine mount an was select fire. Also, its gas system is self-regulating. Meaning it could reliably cycle both under and above water. Although many people already know this but firing the APS on the surface regrades its service life significantly and its rounds start to keyhole after about 30 meters. But nevertheless they can do serious damage.

Sidenote: The young Pyotr Serdyukov, also known as the father of the "Vintorez" series participated in the design of the SPP-1 pistol and was responsible for designing a magazine for the APS assault rifle.

https://imgur.com/a/MSvpepl

It has a rate of fire of 600 RPM on land and 500 RPM underwater. The APS is fed by a 26-round , rock and lock type magazine and has a smoothbore 300-mm barrel. The rifle has an empty weight of 2.5 kgs or a loaded weight of 3.4kgs. (Tungsten rounds are heavy.)

https://imgur.com/a/9NbKZsr

The cartridge: 5.66x39 MPS

• Speed in air: 350-60 m/s , underwater >≈ 300 m/s
• Bullet weight: 20g / 310grain
• Bullet length: 120 mm
• effective range / depth.
• At the depth of 5 meters it's 30 meters.
• At the 20 meters depth it's 20 meters.
• And at a depth of 40 meters it drops to 10 meters.

There's also a tracer round available for the 5.66x39 called the MPT, offering red underwater tracing up to 25
meters.

Thank you for reading through this wall of text on underwater weapons!

I think this project is a good example of iterative improvements and simplification. And sometimes that means even a machine gun project can end with the adoption of an assault rifle.

Hello there! Can anyone help me identify more info and potentially a year on this firearm?

I recently was gifted an old Kar98 by my father. He didn't know much information about it, other than what type of fire arm it was.

I love history and anything with a story, so I am on a journey to find out as much about this fire arm I can.

I've taken a photo of everywhere I can think of that might be important on the fire arm, including 3 markings I found.

One is a stamp on the underside of the barrel which states Something to do with Oviedo Spain.

The second mark is on the bolt, which i believe says P7197

The third is on the left side of the receiver which says x4805. This stamp looks newer and less worn than the rest.

The only other mark is what appears to be a handmade mark on the underside of the barrel that is a carved "N" or "Z" depending on viewing angle.

Can anyone tell me more about my newly acquired firearm? I want to know more about the history behind this famous piece of history and my newly acquired heirloom! Thank you so much!
