I have seen plenty of pics of the PWS FSC556 itself, but cannot find a pic of one mounted on an AR. Anyone care to oblige?
Feel free to include any thoughts/reviews you might have
Here are a few pics of the FSC30, NOT a FSC556, so take this with a grain of salt.
It looks like a monster on a pencil profile, but makes the 6.8 feel similar to 5.56.
The additional noise is minimal to me shooting, however guys standing behind said it’s blasty (they weren’t to the side, but rather at 5-7:00 behind me). Not like a full-on brake, but certainly more than A2.
You will read plenty of good stuff about the design, and just a few criticisms…whether you will like it or not depends on your purpose.
ETA: a little searching turned up…

Same rifle, different configurations…
Works well.
Thanks guys! Im sold. Ive heard nothing but good things, but needed to see it mounted. Looks great
I have one on the Carbine:
And one on the SPR:
I just mounted my FSC556 w/YHM threads to my LMT piston upper so I took some pics. I was fortunate enough to not need to use the peel washer because hand tight using a crush washer was 20 degrees out as per the instructions. I grabbed a wrench and indexed it right to 12 o’clock w/o requiring a peel washer. Here’s some pics:
How much extra length did that add to your barrel? I’d like to add one to my 14.5" barrel, but don’t want it 17" long.
Looks like it adds just over 2.5" to the length.
don’t use that with a can and a crush washer, you will get a end cap strike. You need the peel washer. Crush washers sag when heated
Damn and here I thought I was doing good getting it aligned w/o needing to use the peel washer. It’s quite snug at 12 o’ clock so I assumed it would be alright.
Well if you’re actually going to be using it with a suppressor then I would definitely stick to instructions to the “T.” I would actually go one step further and ship your upper off to either the manufacturer of the can or, if they won’t/can’t do it, I’d ship it to someone who has lots of experience installing QD mounts for that particular brand of can.
That same info was given to me by USMC03 when I asked about getting my own SF MB556K QD silencer attachment brake installed properly, and he has a lot more experience than I do with all of this, so I listen to him.
Just a thought…

you can try it again. I was about half a turn away when it got really hard to turn. but I made it with a little arm muscle. I even shoot full auto with it . hasn’t turned after 500 rounds.
Here’s another shot
Try what again? Who are you talking to?
refering to post by jer.
Which one? The fact that I used a crush washer?
