Default Sig Sauer 556 Swiss SANS Journey + MFI Upgrade

This project will probably one of my longest running ones. My plan is to convert the US Sig Sauer 556 Classic into a replica of the Swiss 550/551 series of rifles. I am unsure if I will decide on the 550 20" variant or the 551 16".

In order to get true SANS parts, It'll cost $$$ and by the time that I'm done, it would probably cost just as much as finding a true one, however we are in CA and that is pretty much impossible now. I don't need it to be perfect, just close enough for me.

In the mean time, little upgrades will come with time including the refinishing to the Swiss gray paint. I've accumulated a few parts over the years.

So far, I have:

Sig 551-A1 Lower
- Sourced from a local member
550 OD Green handguard
- Sourced from a local member
MFI SANS height top rail w/out fiber optic (US Spec was rail mounted and higher than the original)
- http://mfiap.com/i-23899515-set-mfi-...uper-sale.html
MFI SANS front sight hood with fiber optic (required with the SANS height)
- http://mfiap.com/i-8688698-mfi-sig-f...lack-only.html
MFI front sight donut roll pins
- http://mfiap.com/i-10781653-metric-r...tructions.html
MFI HK style hooks 1.25" (x2) for use with the Magpul MS1 Sling
- http://mfiap.com/i-7873000-mfi-hk-st...1-25-wide.html


Need:
550/551 upper conversion
ODG pistol grip
ODG Swiss Stock
Swiss paddle type mags




I've since installed the MFI parts.












The MFI parts are VERY high quality. Installation was straight forward and instructions were pointed out on the website. I am very glad that MFI stays true to the Swiss SANS heritage of the 550's legacy.

I would probably add the bipod kit and the Swiss style takedown pins for novelty sake, but they are not as important as the remaining parts. I'd like the SANS style flash hiders, but I intend to go featureless so the $14 Rousch Sports muzzle break will have to do.

I will continue to update this thread as the progress advances. Stay tuned!

I showed her your comment and she started chuckling. I lucked out with her for sure. I'm going to teach her how to utilize my arsenal soon.

Mike Frost, the owner of MFI, sent me an email and advised that he would assist me in my conversion since he will doing one or two on his own.

This will be a fun journey indeed.

Thank you. It'll be a good time. I'm waiting for my special order of parts to arrive for the conversion.

I won't be welding the sights on to match the Swiss SANS versions.

Default 1/28/17 Update: MFI Fiber Optic Rods and Versa Bipod Adapter

MFI fiber optics rods (rear) and Versa Bipod adapter installed. Waiting on my Versa Bipod to arrive. I prefer this method as I can use it on multiple rifles via the Versa adapters. You can also see the $14 Rousch Sports Foxhole muzzle brake here.

MFI FO Rods: http://mfiap.com/i-23899552-mfi-fibe...-x-2mm-od.html

MFI Sig 556 Versa Bipod Adapter: http://mfiap.com/i-15903589-limited-...pod-bipod.html





Rear focus:




Front focus:





You can see how the front fiber optic side folds down and is higher than the standard sight. This is standard across the board for Euro rifles.




A few last vanity shots:

Versapod Bipod Model 1 (150-001) finally arrived. This model has the Pan Tilt and Cant ability. I opted for the Ski feet per the recommendation of Mike Frost at MFI. This is the only difference compared to the original option available by Swiss Arms.

Example of a 551-LB with Versapod:




Mine. The P320 is a Compact slide (.357 Sig) mated to a Sub-compact frame. I am using the SC extended baseplate created by a SigTalk member, DPeter85 from nxgen tactical (I still need to repaint it).

Where did you get the Sig 556 Versa Pod Bipod? That is a sweet setup. I'm using grip pod right now but once I go featureless, I cant because its also considered a VFG..
Or is there anyway to solidly mount a small picattiny rail on the swiss style handguards?

That's for the bipod mounting adapter, not the bipod. The bipod is not available and he stated that he was waiting on it, I was thinking maybe he got it someplace else. I hope. Thanks though

Thanks, folks! It's been satisfying so far. I'm probably going to upgrade to Shooting Sight trigger, but I don't really have a problem with the OEM trigger.

Shooting Sight 556 Trigger




I eventually found the specific bipod through Amazon. Optics Planet apparently had some in stock, but you can also order direct from VersaPod.

Amazon: Versa-Pod Model 1 (150-001)


Mario, your rifle didn't come with the picatinny rail sections? You should've received a few for the sides and the "cheese wedge" one for the bottom of the handguard.

I also forgot to mention that the MFI top rail with Swiss height diopters are a tad longer to help take up the slop of the handguards that was a common complaint amongst the Sig community. You can see the gap in the OEM photos.

It's nice and tight now with little to no wobble.

You're probably economically better off running the US spec diopters on them.

I'm actually looking for a 522 simply because I have my US spec ones sitting around lol. It'll be nice to be able to run the folding stock.

EDIT: I did read that the 556 US diopter is not calibrated for the .22LR so IDK anymore

Since photobucket sucks, I've moved to Flickr and restored whatever photos I still had. I lost a few, but the thread should be fine.

Where did you get the Swiss gray paint, and who did the rear sight welding?
Working on a similar project myself.

Range day @ 50 yards. I changed out the Rousch Sports MB for a Surefire ProComp. Noticeable difference in control.

I was using he 200 meter peep sight with and the non-FO front sight to zero. Other shots were experimenting with a combination of FO/Non-FO and CQB/200 meter peep.

I maxed out the rear sight's windage and elevation. I had to adjust the front sight's windage a bit, but not much I can do about the elevation. It's dead on at 25 yards using the non-FO blade and 200 meter peep so I should be good at 100 yards via the same combination. I found that the open FO sights were a bit more difficult to use, but for CQB purposes it's combat accurate.

Default Sig Sauer 556 Swiss SANS Journey + MFI Upgrade

I'm enjoying your thread. Thank you. I have a sig 551a1 and bought a set of real Swiss sights for it a long time ago. They were stupid expensive(around $600) and you can't get them any longer. This was before mfi offered theirs. I'll try and get some pics up in your thread if you're ok with that. I think gm4speed had a set on his sig556 also. Not sure if I'll ever change the lower to a Swiss steel one or not. Maybe. The sig USA aluminum 551 lower is pretty nice. The bonus is mine is already sig grey so a steel lower will match. Got a bunch of rock n lock Swiss mags. 5, 20, and 30 rounders. Thing runs like a sewing machine. Pretty funny my 5 rounders say "for law enforcement only"!

Go for it, nitro. Contribute as much as you'd like. I have a 551-A1 lower too, but no Swiss mags yet. I'm still searching for ODG furniture as well.

I have BNIB Sig 522 on order from Big5 thanks to the notification thread by CGN member: Fred C Dobbs

http://www.calguns.net/calgunforum/s....php?t=1364472

I'm only sure that it's a Classic, but not sure if it's a Gen 1 with the 556 style gas block and adjustable stock or the Gen 2 style with the updated gas block and Swiss style stock. If it's the Gen 1, I should be able to utilize the MFI bipod adapter and the Versa Pod. If it's Gen 2, I'll have to tinker with it.

I plan to scope it and will post updates here as well. It will be nice to utilize the folding stock and pistol grip on this being that it's rimfire. I need to find a 20" barrel also, but not for the $210 asking price at Optics Planet. I'd like to turn it into a 550 Sniper clone in .22 LR.

Congrats! We have a sig 522 also and it's my wife's favorite rifle to shoot. I bought ours from big 5 also. Bummer for us is that big 5 orders all their 522's for all their stores with a welded on flash hider. Sucks because I would like to add a suppressor to it. I'll end up selling it and buying one from another store so I can get to the threaded barrel easily. I put a railed front end on our 522 so I could run HK 416 diopter sights on it. Very nice!

Thanks!

The 416 elevation drum runs fine for the .22LR calibration? Obviously, it would be hard to take it beyond 50 yards, but it's a nice alternative to the Sig 556 sights which aren't calibrated for the 522. I researched it after I removed my US spec sights off the 556.

I'm going to use this rifle to train newbies also. My little lady started to take up shooting recently. After 2 range sessions, I let her go on her own without my instruction with pistol. At the end of the session, we tested her current ability and she nailed the headshot at 25 yards. She was happy and I was proud of her then I had to be a jerk and also nail the headshot at that distance. LOL

They work fine on mine. The individual diopters obviously won't work for the different distances, but pick one and zero it to your most common preferred distance. The HK drums are adjustable. You can either get the special tool or do like I do and use thin needle nose pliers to release the drum for zeroing. I only use the 200m diopter and have it zeroed at 50. I'll get you some pics of the 522 also. I use black dog mags in the 522. They work great. If you go that route spend the extra money and get the ones with the metal feed tower vs the cheaper plastic.

Understood. Ideally, the peep sights would be best for target shooting since the open V notch takes a little getting used to just like on the Swiss Sig sights.

I have a set of 416 sights from the middle stage of my Sig 516 build due to using the VLTOR CASV handguard system (see signature line for thread). I used the HK Trigger Return Spring pliers from HKparts.net to adjust them, unfortunately I ran out of elevation adjustment for the setup so I scrapped the idea and modded the handguard further to utilize appropriate AR height sights and achieve co-witness.

416 sights:


Modded handguard to use Sig/Samson sights:

Here's my 551a1 with the real Swiss Sig/San sights. 5, 20, and 30 round Swiss mags. Sling is German Army HK G3 surplus. Still need to add the bayo lug.

Here's the 522 with HK 416 diopters and samson railed front end to allow mounting of front sight. And the stupid *** welded FH that I didn't realize before I bought it thus preventing me from adding a screw on can. Sling is German army HK G3 surplus, mags are black dog with the metal feed tower.

Thanks buddy. It's as close to a real Swiss Sig 551 as I need to get. I don't want to pay the huge $$ just to have one in the collection. These are functionally identical, so for a fraction of the cost you get the full 551 semi auto experience of shooting one, learning their ins and outs, and working on one, without the exorbitant collectors cost, which is close to 10 grand currently. I think I paid about 1500 for the 551a1 when it came out. Sights were 600ish.

Here she is! Sig 522 Classic with 16" BBL. It's the later variant with the revised dummy gas block, but still has the telescoping stock instead of the fixed Swiss style stock.

I'm going to put a .22LR rated scope on it and let the little lady enjoy yourself. It's still MY rifle though lol.

If anyone has a 20" BBL, Swiss stock, or old style dummy gas block lying around, I'd be glad to take them off of your hands. Thanks

Sig 522 variants are, by far, the best .22 "tacticool" rifles out there in my opinion. I've got a bunch of them, including the target model with the floating barrel and included scope, and they've never had an issue. Shot a bunch of other "AR conversions" and had a ton of issues with them - maybe I'm just unlucky.

Regarding the US diopter sights - be super careful with them. I have them on a few R556 guns, and in every case they shook themselves loose after a few hundred rounds. Fortunately, I always retraced my steps and found them, but now I use Loc-Tite blue on them.

I know this thread is all about reproducing a 551 - but for those that can't find a 551 lower, do a search on a 556 DMR lower. Those things are absolutely out of this world when it comes to quality, and they pop right onto any 55x Sig upper. I was lucky and had a connection at Sig who got me a couple dozen of them for dirt cheap, and I've replaced the standard lowers on all my Sig rifles. It was cheaper than replacing the trigger - and you get the nice stock to boot. When I move to a free state, I'll pay the tax stamp and pop them onto my P556 collection.

That's the Gen1 style lower with the Swiss internals, correct?

This one?

Yup, that's the one. Sig promised the 556DMR for a long time, and had a bunch of people with pre-paid orders. They did the production run, and for whatever reason, the demand dropped off faster than they thought it would. They had a ton of lowers available, which were machined a bit better than the standard guns of the day, had the really nice Magpul CTR stocks on them with the cheek-rests, and had the super smooth two-stage trigger on them.

I've got a bunch of R556 rifles in various models, and I've to to say - popping that lower onto them is like night and day. It fits more snugly, doesn't rattle, the stock is really nice, and the trigger is almost match-grade.

Honestly, I was surprised that those lowers went out on the market at such a low price. The nice thing about 55x series lowers is that they're not serialized, so you can buy them without having to go through an FFL. When I heard that they were getting dumped on the market for less than cost, I jumped on them. Nothing like ordering a big bunch of lowers and having UPS just be able to deliver them right to my house without any hassles

Well then, feel free to pass on the Swiss stocks to me.

Also 522 20" barrels and gas blocks. (I have to try).
