New to suppressors. I have a question:

Is the zero shift that occurs when the can is attached/detached fairly repeatable? I’m using a DeadAir Xeno adapter and Xeno muzzle devices. I’d like to be able to move the can around from platform to platform. I have experienced a small shift with point-of-impact when attaching the can. I’m wondering if varying torque values when attaching the can could cause zero shift as well.

Thanks.

I can’t answer all of your questions, but when I’ve had point of impact shifts between having a hand-tight direct thread suppressor on a bolt action rifle or not, they have been consistent. My ballistics solvers have different profiles for whether a can is on the gun. The best way to know for certain, of course, is to experiment and determine for yourself. I get POI shifts with some guns and ammunition, and not with others.

It’s the can, not the mounts. Nature of the beast with some designs. At least with the Xeno, you’re getting a repeatable shift because they’re taper mount. Older tech, you didn’t even get that.

I do not own and have not shot the items you discuss. However, I own a number of cans for rifles, and a few for pistols.

I don't really experience a noticeable POI shift with suppressed pistols.

Some of my AR-15s show a directly downward shift of 1/4 to 1/2 MOA with a can. These tend to be light-ish profile barrels, with a Surefire SOCOM can.

My heavy profile precision bolt action rifles generally do not show any POI changes with a can, but honestly I almost never shoot them unsuppressed. One of my 6.5 Creedmoor barrels had a downward shift of 1/4 to 1/2 MOA, but it has long since been retired. Most of these rifles use Thunderbeast cans, with either direct thread or CB brake attachment. I dismount my rifle suppressors after every range session, and switch many of them between rifles. I haven't experienced POI shifts from one session to the next.

I appreciate the replies.

I’m trying to squeak the most accuracy I can out of everything and want to assure I’m not stacking issues by either varying torque values or the variables involved in the taper mount itself. I’m trying to avoid sitting at a bench slinging lead and chasing my tail.

Correct.

However, I recently found that at least with the Keymo mounts, the shift between my Lazarus and Sandman X is very similar. On the same 11.5 BCM

Oh course, on a 50 yard zero, the remove/reattach shift is so minor I don’t notice it. It’s not a sniper rifle.
