Indian Army SIG Sauer 716 assault rifle.

[Rohan Naik]

The SIG 716i TREAD is retailing for approx. $1,300 - a significant reduction over the 716G2's approx $2,000+. No doubt the inclusion of direct impingement as opposed to gas piston, plus the financial cushioning provided by the Indian order, help to reduce the asking price significantly.

can somebody tell me the pronunciation of Sauer?

 

[Suryavanshi]

Yup, we make.

But, they are
1. either copied. (SSS ones)
2. or not up to the quality. (OFB ones)
3. or not AR buffer tube compatible. (INSAS series)

Say we want to incorporate this kind of design on our AR platforms.
Is there a chance of getting copyrighted?

How different does the design need to be so that one can't press charges of Plagarism.

Tull body rail is the need of the hour.

There are two things to consider when copying this.
1. Ornamental Design.
May be the easiest. Just change the shape, even minute change can work.
If the said design patents a hexagonal cross section, make that octagonal and you are good to go.

2. Functional.
The toughest as most of the things are already patented. The way you mount the hand guard, the mounting slots, alignment methods, etc.
You need some serious innovation to check this box.

I guess this is the easiest part.

The Lack of Civilian Firearm is partly responsible for this Design handicap that we are having.
OFB is happy with copy pasting so they don't try anything new.

Add everyone in place of OFB.

For example, the whole shining lineup of Kalyani's artillery are either copied or ToT.

Are these design patented? Means other conapnies can't make a replica of it with slight changes?

The AR-15/AR-10 designs themselves as patented by Eugene Stoner had their validity expire long time ago. No one needs to pay Colt (ArmaLite sold design to them) to replicate that design, so long as you don't call it "AR-15". Dozens of companies in US and elsewhere produce guns based on AR-15/10 design, including Pakistan's POF.

However replicating the design doesn't necessarily mean you can replicate the metallurgy or make it equivalent/better. That requires investment and R&D.

I think the metallurgy part is covered by DRDO or even any IITs can do the job.

The only place where Metallurgy comes in play is the Gun barrel,bolt, Trigger Mechanism and Gas Piston.

Why the fcuk this metallurgy thing keeps coming again and again!!?

Even I can name all the alloys and their respective heat treatment needed for a firearm.

Please do

 

[Lonewarrior]

Please do

Hahaha, again?

416R/4140/4340 for barrel
416R/4140/4340 for bolt and bolt carrier and other high performance parts.
6061 and 7075 aluminium for receiver, handguard, and stock.
303/S-7/404 for FCG parts.
Glass reinforced polyamide (Nylon) for plastic parts.

Also if u don't mind are there some specialised machine involved or the good old lathe machine are enough?
Can the Aluminium parts be 3D printed?
Do u have any blueprints of some sorts that mentions the dimensions of standard AR parts?

Yes, what I don't get is why labs like ARDE or even OFB's in-house design teams don't just replicate those designs.

They always try to complicate the process. OF Trichy for example wanted to produce a 7.62x39 rifle and instead of replicating AK design which would have been straightforward approach, they decided to adapt SLR for this calibre!

Later on thankfully they realized their error and decided to just copy AK.

ARDE could have just replicated a modern piston-driven AR-15 through and through but they got cocky and messed with several things like gas system, handguards etc which only made it more unwieldy and less compatible with aftermarket kit. Perhaps the multi-calibre requirement served to complicate the process beyond a necessary level.

1. Naah, no lathe. A super expensive CNC will do everything.

2. Yup they can be 3D printed. But 3D printing is only feasible for prototype development, as of now it can't be used for large scale production.

3. Sure,

But sadly there's a little bit of problem.

2020 belongs to Bren 2, 433, Radon, ACR; not AR-15.

Not a problem I'll just try to deisgn Barrel and picattiny Rail when I get back to college.
My teacher has licensed solidworks.

Welcome to my world.
Hope it'll be less harsh to you than it's been to me

All the best.
