QD systems are a weak link for a precision rifle. They are an extension of the assaulter system, actually, they are more a Quick Attach vs a Quick Detach. You are not quickly detaching a hot can and the release gets hot too. Honestly, there is no reason to quickly do anything with a can.
The 90T fixed the wobble in most cases. I have the Titan QD for my PSR too, and it's a great can but super expensive originally. I have brought it to private classes with guys who bought the PSR and did not get the can and swapped it on numerous system without issue.
I have seen levers on QD cans break off, which is why you see guys default to a system like TBAC.
A precision rifle can should be about precision vs quickness. Suppressors can enhance accuracy or they can screw it up. Picking the rifle precision rifle can is important
The Titan is a decent can if you can find it at a discount, but if you want the best precision rifle suppressor TBAC
