Some cool accessories for anyone who wants something different from their Swiss rifle.

Anyone out there have either of these items?

Enables the use of any rail mounted front sight. Really only useful for flattop versions. The one that's on some of the other forums is from a company called RB Precision.

How about this? Nicest looking AR stock adapter I've seen yet. Made by Double Diamond Law Enforcement Supplies. So you can use any AR stock and still have the folding capability of the original Swiss stock.

way she goes, true but there are some folks, not me, who still like messing with perfection, that is exactly what keeps the economy going, folks selling stuff to folks who don't need it. Nothing wrong with that.
 
I do like the idea of that stock adapter. My full length rifle does sometimes feel a little ungainly when I'm square to the target, and it would be nice to lose an inch or so of stock length on occasion.

Hmmmm - Nope: Wife would beat me to death with rifle, if new accessories came home for it!

The Swiss Arms rifles are already perfection. No need for bolt on plastic front sights and AR butt stocks.

I don't know about perfection. Depends on what your idea of perfect is and what your intent for the rifle is. Don't get me wrong, they are one of my favorite rifles and I have owned many of them but I don't think they are perfect.

For example, I'd prefer a non-reciprocating charging handle on the left side. I have to reach over or under with my support hand to work the action, like an AK.

The "back up" sights on the flattop variant suck. The front blade is too fragile and the rear is a tiny leaf sight that you have to dig out of it's slot in the top rail.

If you get the non-flattop and you'd like to use an optic, you have to use a bolt on chunk of rail. Usually a cheek piece is also required in order to achieve a correct cheek weld due to the fact that your optic must be mounted high enough to clear the irons.

There is no free float hand guards available at this time. If you want anything on the front of your rifle you must use either the plastic hand guards with a bolt on rail or the very expensive B&T quad rail. After using both, I'm not confident either would be suitable for mounting any kind of aiming device (IR laser). There is simply no way to hold zero. Both would be sufficient for white light.

A mediocre flash suppressor is permanently part of the barrel and does not allow any other options.

The stock, along with sloping down and requiring a cheek piece for optics, is not adjustable for length of pull. If I want to shoot with gear on (vest and armor) I'm stuck with the length. There is the option to purchase the aftermarket three position stock for around $500 CDN.

If I want to sling the rifle, in it's current form, I'm relegated to some sort of "HK Style" hook attachment points. Personally, I prefer a two point sling with my rear point on the butt stock and the front point at the rear of the hand guards. There is no point near the back of the hand guards. My choices are WAY up at the front on the gas block or on the back of the receiver which turns my two point into more of a single point and the rifle into a pendulum.

These are just some of the things I dislike about the rifle. I still own them, because despite all of my points, they shoot extremely well and they have a solid design under the hood.
 
Some interesting points. If you run that thing bone stock it handles and works beautifully. As soon as you try adding aftermarket stuff it was never designed for, you now have a compromise in balance and handling.
I have no need to run optics on my rifle inside 300m so for me it is perfect as is.
I am 6'1 200 and the Classic feels like a toy in my hands so that also helps ergonomics in my case. My only gripe was the sling mounting points as well but that problem was solved with Paracord loops.
 
If someone figures out how to make a FF fore-end without butchering the rifle, then we are talking. Otherwise, nothing really needed.
 
If I was a machinist, I'd be milling prototypes of kit including a FF rail specific to the SA fow a long time ago... Unfortunately, I'm not, and life gets in the way.
 
I might design something and run a one off. I've been tossing a few ideas around in my head for how it might be possible..

Lets say that 95% of the sigs out in the Canadian market are iron sight models, so from a manufacturing stand point, it would be best to design with that in mind.

Would it not be feasible to design a rail system that utilizes the same mounting method along the top of the rifle as the B&T top rail does? To add more support, you could make the bottom portion like the B&T quad rail and link into the front take down pin. The rail could even have more support under the rear portion.... Some sort of clamp that could snug up around the half inch or so of receiver that the barrel threads into.

Obviously it would need to be a two piece design for ease of installation. Troy makes a good design but it is engineered for the American Sig 556 and it uses the front for support, so not a FF design.
 
Something that mounts up to the dovetail and front of the Diopter as a mount (much like top rails or the case deflectors do) and that indexes on the front takedown. Slide over the two piece railed portion ala VTACs FF tube for ARs (as you mentioned a two piece sollution - but rather, really a three piece in this instance) and I think one would be off to the races. If it was done right, in my mind it would essentially be a continuous top rail with quick disconnect sling attachement points on the sides & bottom, and the tube would be just that with mounting points for future rails on the sides and bottom (again, much like the VTAC AR tube).
 
I would think something that would mount over the dovetail (maybe using it as a forward movement stop) and uses the rear iron sight to lock into (like the normal B&T style mounts). then have a big clamp of some sort that clamps it to the barrel from underneath, and then have the bottom lock in I guess like the B&T one.

But without the top studs (like the US versions) I dont know if the factory mounting systems alone would be good enough...
 
Those ideas are what I was thinking, but I need a way around using the front dovetail mount since I run a flat top with low optics. The receiver protrusion and the front pin index are all there is really to work with, unless you grab the first slot of the picatinny. I know a lot of scopes need that first slot though, so it isn't straightforward.

Alternatively, if you can live with the higher optical axis, the top rail could be continuous and cover the whole flattop and cantilever over the gas system all the way to the end. A second piece (essentially a mounting plate) would clamp the receiver protrusion and index on the pin slot and a third would tie the other two together and provide the 3, 6 and 9 o'clock rails.

I've also got a flattop and unfortunately it is going to be tough to design something that doesn't use the top rail. That means a higher rail like you say. I think if you kept the top rail low enough, it would be OK...not perfect but OK.

I've got a few designs I've been doodling. If I get something workable, I might make one. I've got access to a six axis CNC machine and a full metal shop so I might make a prototype.
