Care to take any pictures of the pin bracket in one of your AKs for me, Spree?

Care to take any pictures of the pin bracket in one of your AKs for me, Spree?

From the last thread when Corda was working on something (perhaps I telegrammed it?):



Apologies for the blur, but I will describe what you are looking at:

Just above the chamber you will see the forward trunnion that houses the chamber area of the barrel. You can see that it also extends around the left forward portion of the receiver, and just above the chamber itself, there is a pin (visible at the front-right of trunnion in this photograph, directly above my import marks). Connected to this trunnion is the rear sight block that, as you can see, goes forward and is also pinned in place on the barrel. If the cut-out on the barrel for the trunnion pin is cut correctly, and the trunnion pin is sized correctly (have never heard of either of those not being made correctly), I cannot think of any reason for it to fail outside of improperly-hardened steel/incorrect steel. Basically: unless you screw up and use completely incorrect building materials, you aren't going to have a loss in anything but production time. The only reason this makes manufacturing slightly more difficult is the fact that the barrel has to be pressed into place rather than screwed in. With proper machinery, though, it is something that really does not matter as it will probably still be just as fast in the grand scheme of things.

The Type-55 Directed Energy Rifle is the primary rifle of the Empire. The weapon is infamous for its accuracy, its supreme range and its power, as simply having it pass near you is enough to kill.

Still working on what to add and all that but thats what I have so far for this thing, more will come later.

How does this affect the ability to remove the barrel?
Still trying to wonder if I should use some form of a removable bracket to which the barrel is pinned, how I can make a conventional pinned barrel work, or just to say 'fuck it, screws'.

[Nua Corda]

Nice M1919.

Also, those logistics aren't suicide worthy it's p. much any European army.

4 different rifles (one of which is almost identical to one of the sniper rifles)?

2 different (but identical in purpose) shotguns?

2 different pistols?

2 different SMGs?

Only thing I see here that's justifiable are the pistols/SMGs, but only if the heavier caliber versions are for use with suppressors (and there's a specially variant of the MP5 for suppressors, and it's very well known), and the sniper rifles (though the 7.62mm AR-10 derivatives should be standardized).

To insert pinned barrel:

Pressure fit into place, hammer in pin.

To insert threaded barrel:

Screw into place, drill gas port afterward.

To remove the barrels on 'em? You'd have to basically take everything off of both since almost everything on an AK attaches to the barrel in some way, so it really wouldn't make much difference there. I think it would come down to the final steps being:

Pinned: remove pin, pull barrel out (probably with a vice or something).

Screwed: Unthread.

Pinned is easier for assembly because gas ports and handguard retaining slots can be made before insertion. Slightly less-easy for disassembly because it is more or less a two-step process. As far as I know, a threaded barrel would have to be threaded on as a "virgin" barrel with nothing "installed" on it as it could rotate slightly more/less than the previous barrel. Therefore, after threading, you'd have to do your handguard retaining slots and then drill your gas port. As for removal, it's basically just "unthread" after you've stripped everything down as you would, regardless of barrel type.


I guess they're really not that different aside from, "mass-produce completed barrels" versus "mass-produce virgin barrels". Even then, you might check out www.akfiles.com and look and see if you can find anyone talking about their own home-built milled AKs. I am 99.99% certain the information I've given you is correct, but being able to talk to someone who has gone one step beyond me (observed and assembled/disassembled entirely) will be able to provide more information, I'm sure.

Introduction

The Frekagiwar of 1895, better known as the FG 95 is perhaps the first assault rifle to be accepted into service and widely issued by any nation, making it one of the most important firearms developments of the late 19th century. Serving from 1895 to 1950, it is still used by many members of the civilian population for hunting and target shooting, while other surplus rifles are sought after by collectors and museums. Still in use in some areas of the world today, it is also the oldest assault rifle to still be in active service, having been used in the service of various militaries around the world for 118 years. As such, it can be considered the most influential assault rifle of all time.

History

The FG 95 can be said to have it's origins in the patent filed in 1870 by a Swede named Friberg. The patent was about a bolt with retractable locking lugs, which would eventually evolve into the flappers used by the FG 95. However, the first recorded studies into the action used the original design. The document, dated the 18th of May 1873, discusses the potential of the locking system for use in a self loading firearm. It concludes that, while having much potential, current cartridges cause too much fouling for the weapon to ever be accurate, and that a satisfactory method of unlocking the bolt had yet to be found. The idea was shelved for the time being, but was never fully forgotten by the priests of Frauja.

It was not until 1886 and the introduction of the first successful military cartridge using smokeless powder - the French 8mm Lebel cartridge - that the idea of retractable lugs was revived, as the world scrambled to take advantage of this new development. In Triggairþa, some priests of Frauja began to develop their own smokeless powder while others began to develop a new rifle in collaboration with the military order of Fraūw and advisers from the cult of Woþinas. It was soon decided to not only abandon the old ideals of single shot rifles with slow, large caliber bullets, but to also pass over the current trend of bolt action rifles. By 1888, it had been decided to arm soldiers with self loading rifles chambered in a small, fast bullet and supported at a platoon or company level with machine guns firing a large caliber bullet at ranges beyond what the rifles were expected to perform, which was under 300 metres, given past experiences and exhaustive studies of local terrain.

Work on a self loading rifle had been undertaken on a private basis by several of the priests ever since 1884 and the development of Poudre B, and thus had a head start over their rivals both within and outside of the order. One of these priests, Tigōþragjan, had been working with the Friberg system since 1885, and had actually produced a prototype chambered in 8mm Lebel in 1887, before the decision to even develop a semi-automatic rifle had been official reached. It was a complicated short recoil operated design with very little similarity with the FG 95, but the bolt design was beginning to resemble that of the FG 95.

Impressed by Tigōþragjōs progress, the committee teamed him up with the experienced firearms designer Galdranbāl and Lt. Rōfpliht, an infantry officer whose own firearm design was considered quite advanced. The end result was a self loading rifle that incorporated Tigōþragjōs bolt and Rōfplihtōs short stroke gas system. Lighter and easier to produce than either designer's previous designs thanks to improvements and suggestions made by Galdranbāl, it was considered quite promising. The first prototype in 1890 proved to have superior reliability and cost than competing designs, but was still considered too unreliable and inaccurate to be used as a primary service rifle.

Several redesigns later, the FG 95 had evolved into an assault rifle, with the unsolicited ability to fire on fully automatic being added to the second prototype provided for testing in 1893. At first the military was concerned about troops wasting ammunition, however, they were soon convinced by Galdranbāl and Rōfpliht that the select fire capability was of use and that it wouldn't be abused by well trained soldiers. In truth, the military didn't need much convincing, as the idea of turning every soldier into a machine gunner was quite appealing, even if that idea was never actually used. Nonetheless, the fully automatic setting gave the rifle it's name: Frekagiwar, the "greedy firearm". All future assault rifles would be referred to by this name, in the finest traditions of self-mocking humour.

The three years of extensive development and private tests had paid off, and the prototype exceeded expectations. It was accurate, reliable under all conditions and provided soldiers with such an increase in firepower that enemy nations armed with bolt action rifles would be badly disadvantaged. The result was the FG 95 being formally adopted and first issued in 1895.

Design

The FG 95 is a gas operated, short stroke, flapper locked rifle and, as such uses a bolt with two flappers which are pushed out from the bolt by the shape of the firing pin when the trigger is pulled. These flappers lock into recesses in the lower receiver and prevent any rearwards movement of the bolt following the firing of the round. The location of the flappers and their slots at the rear of the bolt results in them experiencing compressional forces rather than the shear forces of the flappers in the G41 rifle. While this doesn't necessarily result in a more reliable weapon, it does allow for better flapper life if they aren't machined to within standard dimensions.

After each round has been fired, a portion of their propellant gases is diverted into a gas tube, where they act on a piston. This piston then taps the bolt carrier, which continues to move rearward due to the momentum imparted by the piston. The bolt carrier has an extrusion which slots into a hole in the firing pin. As the bolt carrier moves backwards, it pushes the firing pin backwards as well, allowing the flappers to retract into the bolt and for the bolt to travel rearwards as well. A recoil spring then returns the bolt to its original position, stripping a round from the magazine as it does so. A bolt hold open device prevents the bolt from returning to battery if the magazine is empty.

Heh, you're right about it being more appropriate to the realism thread.

but its almost going to get answered by the same posters regardless.

True enough .

[Samozaryadnyastan]

Every time I try to modify my Doberman, I just find that I spend hours staring at my FAL receiver drawings.
The FAL looks awesome as nothing but a barrel, gas tube, bolt assembly and lower receiver.

Especially that 12-inch barrel that I stretched to 14.5

[Registug]

Any suggestions for a good replacement to the EF88 in 2030? Or should I keep on trucking with what I got?

Yes, I've been using the gun that long IC. F88 has been in service in Registug in various variants from 1991-2030+

[Samozaryadnyastan]

Thales F90.
It's a modified F88, so you could retcon switching to the F90 a decade or so ago.

[Registug]

"The F90 is identical to the EF88"

Er...

[Samozaryadnyastan]

It is slightly modified.
Wait until Aqi shows up, and hopefully he'll agree.

Besides, it looks more futur than the F88.
Oh, I get it.
It's identical to the EF88, but both are modified versions of the F88.

[Registug]

Well that was coming from the official Thales website.

I feel that changing from an EF88 to F90 around the 2020's is a rather negligible upgrade...

'Course, I could probably keep it in service for another few IC decades yet, just add more BATTLENET attachments.


Music player, anyone? :P

[Samozaryadnyastan]

Well, the F90 is an export EF88.
F90 has a couple additional useful features, like STANAG compatibility with its magazines.
