View Full Version : SM556 aka "Short" FSC556
Where to find online to purchase.... Need one ASAP!
I haven't heard of that model, but Addax Tactical has the Bulldog which is a
FSC556, with shortened tangs.

thats it.. damn 50 bucks more than the standard fsc556...
Are these as effective as the standard fsc556 in terms of a brake ? Sorry for a thread drift. I found this model on a couple of sites for $150.
Primary Weapon Systems FSC556 Tactical Compensator for the QDSS-NT4 Suppressor
It serves as a mount for the KAC NT4. I have one but have not fired it yet. As I do, I will be posting more info on it.
Check out 03 Design Group (http://www.03designgroup.com/) for more info.

is there a standard SM556 that is not the $50 extra suppressor mount?
I can't seem to find a review for this particular muzzle brake. Besides mounting the KAC suppressor what makes it different enough to be more expensive ?
If you want a PWS even shorter then grab the TTO (http://primaryweapons.com/store/pc/viewPrd.asp?idproduct=88&idcategory=6).
The TTO looks great but lacks the flash suppressing tines of the SM556 and FSC556 standard model. I apologize for the thread drift I ordered one to try out and will compare it to my standard FSC556.
Is the SM556 the same as the Addax Bulldog (which is made by PWS, I believe)?
The PWS DNTC and FSC556 have the exact same blast chamber and I notice performance in reduction in muzzle rise was equal with both units. The FSC556 has tines at the end of the comp that help reduce flash. The DNTC has no flash reducing properties.
The TTO (Todd's Tiny One) comp is nothing more than a FSC556 with the flash reducing tines cut off. Thus it has the same reduction in muzzle rise as the DNTC and the FSC556. But the Todd's Tiny One compensator has no flash reducing features (the tines on the FSC556 is what reduces muzzle flash).
The FSC556 for the NT4 (aka SM556) has a different blast baffle than the FSC556 / DNTC / TTO. The blash baffle on the SM556 has less surface area. That being said, I have been running the SM556 for several months and find that it's performance in reducing muzzle rise is not as good as the FSC556 / DNTC / TTO, but fairly close.
The SM556 incorporates flash reducing tines, just like the FSC556.
The SM556 is close in performance to the FSC556, but it's 1/4" shorter than the FSC556. You can't go wrong with either compensator.
TTO - 1.65" (no flash reducing features)
USGI A2 flash hider - 1.75"
SM556 - 1.85"
DNTC - 2.00" (no flash reducing features)
FSC556 - 2.10"
The SM556 is only 1/10" longer than the USGI A2 flash hider. If you use a USGI A2 flash hider and a crush washer, it's the same length as the SM556 with a peel washer.
The Addax Bulldog is a modified standard FSC556 (not the same as the SM556)

I've been planning on doing a review of the SM556, but have been burried with other project for the last few months. Hopefully I can get a review of the SM556 up in the next couple weeks.
Hope this helps
Wow Jeff, that was a great comparison of the various configurations!
I take it then that the Addax Bulldog is an FSC556 with the tines cut short...and therefore should have the exact same muzzle brake qualities as the FSC556 and TTO?

I have never used the Addax Bulldog, but it should have the exact same muzzle brake qualities as the FSC556 / DNTC / TTO.
The flash suppressing tines on the Bulldog are shorter (0.15" shorter) than on the standard FSC556, so in theory, the Bulldog's flash suppressing capabilities will be slightly less than the standard FSC556.

The Addax FSC Bulldog Comp that we equip on our Gas Piston Uppers, has the same exact muzzle brake / compensator qualities as the parent comp. the PWS FSC 556.
During some night shooting/testing with the guys at PWS, we did not notice any significant reduction in the flash suppression qualities of the Addax FSC Bulldog in comparison to the PWS FSC 556.
The tines are machined down just slightly, but it looks shorter due to the front slant cuts, but the overall length is just shorter by approx. .10.
Thanks,
Chris

Will either of these work with the new 2009 HALOs?

The Addax FSC Bulldog will not, and PWS states on their website that the FSC 556 will not work with the new Gemtech 2009 and newer Halo Cans due to some design changes by Gemtech.
Thanks for the additional information, Chris. Greatly appriciated!!! :cool:
I've always loved the look of the Bulldog.

I gotta say, that is one sharp looking comp. I have a PWS FSC and I think the Addax is going on the next one.
Sorry to continue with the off topic discussion.

Thanks for the info on the Bulldog. I knew the FSC556 wouldn't work due to internal changes on the '09 HALOs. I was wondering about the SM556, as well, given that it appears to be dimensionally fairly close in dimension to the A2 FH and has a square shoulder in back for the HALO collar to lock against.
I guess I could just stick with the VLTOR VC-1 (I've got a couple of those) but was looking for something with a little more compensation effect that would still work with the HALO for my mid-length build.
ETA - went direct to the source and Emailed PWS. Response was that they do not make any muzzle devices compatible with the 09 and later HALO design. :-(
When we originally designed the FSC556, we made it to fit the current production HALO suppressors. For 09 Gem-Tech made the decision to have the HALO compatible with the Smith Vortex flash hider. We do not plan on changing our design that was already intended for that suppressor. So, currently we do not make a compensator that is compatible with the current HALO suppressor.
I really wish I had an adapter that works for your new HALO, but the FSC and the FSC for KAC both slip to far into the body for the collar to properly secure the suppressor on. The A2 works because it has the raised lip on the forward outside edge of the hider. Enjoy your suppressor and thank you for contacting us.

Sorry I missed you at SHOT, but I am glad you stopped by to see us.

No problem and sorry I missed you as well, Chris. Lots of Addax awesomeness at your booth ;)

So I got two questions:
1. Where can I get an Addax Bulldog?
2. USMC03 - for the SM556, you say that it helps, but it isn't quite as good as a FSC556 or comp that uses the same design. I'm assuming it's still better than a standard A2 flash hider, though, correct? Also, I would guess that it is probably a little more quiet/less side blast than the FSC556/TTO/etc - right?

I don't notice any difference in noise levels between the FSC555 and SM556 wearing yellow foam ear plugs. Both the FSC555 and SM556 are slightly louder than the A2 flash hider.
Hope this helps
So I got two questions:
1. Where can I get an Addax Bulldog?
From Addax Tactical
From Addax Tactical
Addax Tactical no longer lists that item.
Addax Tactical no longer lists that item.
That item is exclusive to them, as far as I know.
I've had the opportunity to shoot with the SMC556 through my middy and comparing it to the FSC556 it is not as effective in terms of its function as a muzzle brake.
I kind of wish I stuck with an FSC556 instead but live and learn right.

Basially I just want a muzzle brake that still hides flash but works better than having no brake (IE: An A2 flash hider). I'd like to keep it somewhat short, which is why I have interest in the SM556. If it reduces recoil/muzzle climb noticeably when compared to a standard A2, that would probably be good for me.
That said, the FSC556 is only about .25" longer than the SM556. Still.... just wondering.
From Addax Tactical
We list it from time to time on our site.
All of our FSC Bulldog comps are currently slated towards uppers we have in the que.
We expect to get more Bulldog comps soon, and we will relist them.
Thanks,
Chris
So any updates from you guys more than half a year later? As Im thinking of picking one up tomorrow. Any thoughts comparing to BattleComp 1.0?
Thx :D
Anyone used a NT4 on the SM556? Any issues with looseness or did it lock up the same as with a QD mount or 3t brake? Im looking at this as a cost saving issue, I want to run a brake on my 10.3 but dont want to pony up for another 3t brake.
