JF I realize this post is older but those 3 cans are the 3 I am basically considering one of at the moment.I've ran the OSS HX-QD Ti on a few different rifles, currently its on my .300 BLK SBR. The first thing I did was test host rifle accuracy using my 18" 6.5 CM bolt gun. I was impressed with the result and like their QD mount. I haven't always had great results with QD mounts on precision rifles. While I had it on the bolt gun I noticed the recoil pulse was more like a muzzle brake vs. a traditional suppressor and suppression performance seemed to lack versus others. Granted on bolt guns back pressure/carrier timing and things like that are a non issue.
On my .300 BLK using sub-sonic ammo the suppression was not on par with a Rugged Surge 762 but not as noticeable when shooting supersonic ammo. My rifle will cycle with subsonic & supersonic ammunition, with or without the suppressor attached. The amount of gas in your face with the Rugged vs OSS is very noticeable.
On a friends LaRue the suppressor did outstanding in host rifle accuracy and POI return but did have issues cycling reliably. I touched base with Randy at OSS and he mentioned incidents where using the suppressor actually slowed carrier speed. I haven't had the opportunity to re-test it using different ammunition. Suppression on the LaRue with the OSS seemed to be on par with the other suppressors we had out that day including a KAC and Surefire. I don't have metering data so comments regarding suppression are subjective.

Any comment on sound to the shooter between them? Will do 300blk SBR, 16 inch 6.5 AR and bolt gun.
Thanks!
