SRD762-QD Taper-Lok Muzzle Brake - 5/8 x 24 TPI is rated 4.9 out of 5 by 7 .

Rated 5 out of 5 by Capt. AndrewD from Quality and very effective. The SRD QD Titanium Suppressor is a very well designed and manufactured suppressor. The simplicity of the single wall design allows for more suppression volume, lighter weight and no moving parts to align or worry about. Spend more time shooting and less time ‘screwing around’ with parts. The SRD is effectively self cleaning with each blast of 30cal cartridge. I purchased two taper lok muzzle adapters allowing me to use my SRD QD on my 6.5 creedmoor hunting rifle and my MCX 300 blackout rifle, on which it performs amazingly!

Rated 5 out of 5 by quickdrawmcnevermiss from Great method of attachment for silencers I have been using an SRD338 on a couple if different rifles for the last few years so having extra SRD muzzle devices has been important. These muzzle devices have worked well with my FN SCAR-17 and a couple of bolt actions, none of which have had the SRD taper on the barrel. Make sure that you secure the brake to your barrel using the Rockset that is supplied because once you attach your silencer you may need a wrench to remove it so it would be good if your brake stays on the barrel. I have also seen minimal POI shift using the brake with or without the silencer, so that can speak to the quality of alignment you are getting between the can and mount.

Rated 4 out of 5 by AZevy from Good System, include more crush washers Overall, I like this system. My main complaint is it only comes with one crush washer. You have one try to get the brake timed correctly. I cannot find additional crush washers anywhere on in the web. Sig does sell them if you call customer service, but they are back ordered with no date. I do like this mounting method, I just wish replacement crush washers were more readily available.

Rated 5 out of 5 by Texas Hill Country from Awesome adapter allows quick and easy switch Love this thing! I have one on my Sig MCX Virtus 300 BLK AND one on my Marlin 336 Dark .30.30. I can now use my Sig Suppressor on both rifles!
