These are my two rifle suppressors I have at the time and curious which you'd recommend running on a PRS style rifle in 6GT. The Specwar is 9" and 24oz, but it threads on to a muzzle device and locks up fairly well. The Griffin 30SD-K is both shorter and lighter (17.5oz and 6.7") but uses GateLok so it has some slight movement to it. I'm not sure if that could induce any inaccuracy in the gun and if just going with a more secure lockup would be better than saving weight/length in an already long and heavy rifle.
