I know, I know, I know, this has been covered many times, but I cant seem to find an exact model number and just wanted to be sure.

I have a Scar 17 I want a Surefire Flash Hider, would the SF3P-762-5/8-24 be the correct one to purchase? The suppressor I was looking at down the road was the Surefire Socom 762 rc.

And to install, I remove every thing from the end of the barrel, muzzle break, jamb nut etc, and screw the FLASH HIDER right on and tighten her down with noting else. Correct? Does it have to be tightened to a certain inch pound? And use Rock Set as well?

Sorry I am still a noob to the gun world. I will probably have a gun smith do the dirty work, I just want to be sure I can tell him what to do if need be.

You might also consider timing the FH with the shims. The advantage, albeit slight, is you can orient the mounting 'bung' at 6 o'clock for quick suppressor attachment reference.

The above is not totally correct--or at least not per the instructions given by SureFire. I just got my SOCOM762-RC-DE this week and installed the FH over the weekend, so my memory of the instructions is still fresh.

Yes, it's true that you don't include any timing shims or spacers when installing the the SF3P to the SCAR barrel. This is not in the instructions.

However, SF instructions do indicate torque values between 20 and 30 ft-lbs. And you most definitely want to use the Rocksett if you plan on running the suppressor. The most important part here is to clean and degrease the threads thoroughly before applying Rocksett else it won't adhere properly. All of this information has indeed been covered here prior (or elsewhere) and is available in the instructions SF provides.

The only other thing that I did, which may be unnecessary, was to torque the flash hider three times prior to applying Rocksett and giving one final torque.

when I called surefire they made no mention of rocket and none was used on my 17....torque value is subjective in this case, just tighten all the way down on the short shoulder and your good to go; a few thousand rounds later and no problems, everything is rock solid. Thats the beauty about surefire!

I just bought a Surefire FH for my SCAR-16 (Marvin Pitts is chopping the barrel and pinning it to minimum legal length right now). The FH did come with very explicit instructions on timing it as well as a bag of shims to do it with. This was for the 556 FH but I assume the instructions and bag of shims come with both.

Thanks a ton for your input thus far!! Do you experience anything near the degree of flash suppression with the standard 16" barrel as depicted in the Surefire video (15s)? Furthermore, can you attest to the claim at the 29s mark "also, it deadens the ringing so common with other three pronged and open pronged flash hiders"? Thanks again in advance!
