The NS Infantry Discussion Thread MkII*

[Purpelia]

Since the discussion died last time. I need it to pick up. Hence, a repost:

Speaking of that, I have a few questions for you all regarding rifle barrels.
Question 1:
Take your average rifle design. The barrel is encased on all sides within the furniture which clamps down on it and keeps it in place. Now obviously, in order for the barrel to go through the furniture it has to have a hole drilled out inside of it. So let's say I take this hole and widen it so that it's say 1-2mm wider than it needs to be. In that case, the barrel would still be completely encased by the furniture but wold not actually touch it. This should allow the barrel to flex freely thus giving me a free floating barrel.

Is this a correct interpretation?

Question 2:
Assuming the answer to #1 is correct the one issue I can see is that dirt or water could get into the system from the front where the muzzle exits the furniture since there would be a gap present there. Would this be a serious problem worth addressing?
And if so, would something like a rubber seal address it in such a way that it both solves the issue and does not compromise the free floatiness?
If not, what would be a good solution?

And no, cutting the stock off at the front is NOT an option. Neither are bullpup conversions or throwing the whole assembly out.

[Bezombia]

Bulpup bolt guns that arent purpose built (read: Conversions) are fucking retarded. 99% of bulup bolt guns are hilariously awkward and really inefficient. The notwithstanding are mostly sniper rifles purpose built (such as the Barrett M95 and Desert Tactical Recon or whatever)

The irony is that whilst this is true the pump action mechanism on my bolt action rifle would actually make for a rather decent way of working the mechanism if it was ever converted.

1: That's not a very good design, but it would be free floating, yes.

2: It would be a problem, but not a dire problem that you'd have to poor millions of dollars into. It wouldn't render the gun useless, but it would still be there.

Well, I've got quite a few little creations of mine to show off. Thanks to Pimp My Gun for balancing out my nonexistent computer art skills.

Without further ado, here's the Thesdan Infantry Armory Showcase.

That first rifle. The UGL is far too forward. The only one I can imagine being able to hold on to both pistol grips and firing the UGL comfortably is Mr. Fantastic. And even that's a stretch.

@Purp: the thing I mentioned earlier where you just make things tight near the muzzle of the barrel should work fine. It seemed to work fine on the Mosin and the Swiss straight-pulls, anyway.

Could you please elaborate further? I know the Swiss used something similar. But I thought all they did was put a simple metal ring around the barrel. Did I miss something?

This one covers Mosins primarily.

[Black Hand]

can anyone give me a remotely sane reason as to why the Mosin's sights' go out to 2000m?
I've wondered for a while ever since I first used the sights on the mosin but was to embarrassed to ask since I own one...

Volley fire.

The M91's rear sight actually goes beyond 2km.

Because fuck you thats why. Same reason why the C96 has iron sights out to 1000m.

That actually makes sense now, though It's mostly useless after trench warfare stopped being a thing.

7.62 mauser or 9X19 at 1000m seems like it would be rather useless.

I "lol"ed when I looked at the rear leaf of the C96 I handled. Yeah, it's got a buttstock, but 1km for 7.63x25mm? Good luck, Hans.

This is confusing. They are actually putting more pressure on the barrel? I thought best results were achieved with barrels that were free floating, as in had absolutely no pressure placed upon them anywhere but the chamber.

Yeah, I know. I'll get around to fixing the foregrip. Eventually. But thanks for the feedback.

Edit: Found the relevant post:

It's not so much about vibration but consistancy. Accuracy is not determined by how small of a target you can hit at a distance but by your ability to repeat previous shots with consistancy. You may be able to hit a dime at 1,000 yards with your .223, but if it takes you 1,500 rounds before you do it then your rifle is not that accurate. That's why long range shooters laugh at 3 round groups; because you should be able to put ALL your fired shots into a group that small if you're rifle is THAT accurate - not just the best three you can muster out of a day of shooting. You're rifle may shoot 16 feet to the left, but if EVERY shot goes 16 feet to the left, than it's more accurate than a rifle that shoots it's bullets within a 1" circle concentric to the bore.

That is why free floating is so popular. There are many variables that come into play, such as stock fit, bedding, etc and by removing those variables you make the barrel rest that much more consistantly. If there is nothing touching the barrel, it will naturally want to rest with its center of gravity at it's lowest point.

Now you go to barrels that have thin barrels relative to ratio of length (a .5" barrel 2" long will be more rigid than a 1" barrel 6" long). These barrels will whip when fired. The cork, or other form of bedding, essentially acts as an anchor, like on a suspension bridge. The result is like cutting the barrel in half and creating a more rigid platform while at the same time forcing the barrel to rest above it's natural point of rest. It is forced to the same point each time; ie it returns to rest consistantly in the same place.

The vibration absorbtion comes into play with rapid strings of fire. When the barrel vibrates with each shot, it causes a small wave to travel the length of the barrel which causes it to, for fractions of a second, to point in different directions until the wave stops. This will obviously through off point of impact. By absorbing the vibration quickly, it causes the barrel to return to natual rest more rapidly so follow up shots will be held closer to point of aim.

It's not snake oil, hog wash, or hocus pocus magic. It's science and it's done for a reason.

Now I just have a serious question. How do I know if my barrel is thick enough to be better served with a FF or thin enough to be better served with more pressure? And if the later is the case, would just adding a strong metal ring near the front do? Because my rifle basically already has a strong metal front cover that encases the barrel some mm after it has left the furniture.

I'm thinking of designing a Rifle, while I'm not as good with graphic design as you guys; I'm somewhat competent with pimpmygun.


Its basically going to be an M4 with internal and external parts of a more modern platform.
