Product Details
PMM Is proud to carry the Surefire 762 Shoulder Ring, The Surefire shoulder ring is now being used as a Standard in all PMM SCAR 17 CQC Barrel jobs.
PMM Highly Recommends the USE of the Surefire SCAR Should ring on ALL SCAR 17/MK20 Barrel’s, PMM Will not be held responsible for Baffle strikes on any PMM CQC barrel jobs Not using this ring to insure Proper Muzzle device Alignment.
The Surefire shoulder Ring solves all of the issues with fitting muzzle devices and suppressors to the FN SCAR 17/MK20 rifle. Due to the small shoulder available on the SCAR 17S barrel from the factory, there are a very limited number of muzzle devices and mounts that will work properly. This ring increases the size of the shoulder by spreading the load of of the shoulder ring uniformly agains the barrel shoulder. It also reduces the length of the muzzle threads to 0.60”, allowing any device or suppressor to be properly mounted.
Instructions:
- Verify that the rifle is unloaded and made safe
- Thoroughly clean the entire muzzle thread profile of any debris, such as dried thread locker
- Slip the surefire Ring over the muzzle with the ID chamfer facing towards the muzzle device not the barrel
- If installing a brake, space out and add the required washers or shims as needed to index properly
- Clean, degrease, and dry the threads on the muzzle, and in the muzzle device
- Add a few drops of the supplied Surefire Rocksett to the muzzle threads and threads of the muzzle device
- Thread muzzle device onto the muzzle and snug ensuring the Ring is seated correctly
- Torque the muzzle device, but do not exceed 35 ft-lbs
- Before firing, always verify proper bore alignment of any muzzle device and/or suppressor!

Just what you need to change your SCAR muzzle device, at a sane and reasonable price!

Ok let me start this review off by saying I have NOT as of yet been able to mount/use the SCAR 17/20 ‘Shoulder Ring’. I can say by all rights it appears to be of absolute quality and exactly what I was expecting…perfectly machined for ‘truing up’ the SF Warcomp on the muzzle. This purchase was the first time for me doing business with PMM and their response in getting it to me IS WORTH 5 STARS (and along with the complete SHIM Kit/Shoulder Ring). They were VERY prompt with no issues on either end, certainly not theirs. I understand they’re in the process of RE-stocking the ‘alignment rod’ fairly soon as I’d like to pick one of those up also. I have TOTAL confidence in PMM’s products going forward and AS SOON as I’ve mounted this on my SCAR (17) I’ll be editing this review with great results I’m sure. Thanks, Mark H.

The best shoulder ring you can use when installing a muzzle device on a SCAR.

Worked great for PSA PA-10 low shoulder barrel and attaching the YHM QD Brake. I was happily surprised that this shoulder ring came with a shim kit and surefire rocksett. I’ll place more orders with PMM.

Scar 17. Shoulder ring is needed to install aftermarket device. In my case a Silencerco flashider. For ASR mount,and 36M. Removing the nut and OEM muzzle brake to save my hearing somewhat. Thank you
