147gr Remington subs, can is in the L configuration with the flow through cap installed, 8” POI shift with suppressor mounted
Ordered a 3 Position A3F Stock from Arms Unlimited and a H&K parts micro pikatiny optic rail, probably going to put an ACRO on it in a B&T low mount if the body mechanics make sense with the A3F stock

Clock/orientate your suppressor using where your engraving is as a reference and shoot it until POI gets to what you'd call acceptable. Then remember the orientation
So with the can sealed it groups well but POI is 8" off when compared with the suppressor.It’s the can itself… View attachment 385127View attachment 385128
The only configuration that works is the K sealed , everything else destabilizes the bullets somehow
So with the can sealed it groups well but POI is 8" off when compared with the suppressor.
When the can is configured in the other ways the groups open up and the POI is off (as compared to running with. I suppressor) as well?
Is the can config changing back pressure and impacting the roller delay or something else causing this?
What distance?
Been looking at the sqd for my sp5k as well. This isn't the first reports I've read about serious poi shifts. Idk what's going on with this can or b&t's constant dropping of brand new models. I'd love to buy it for simplicity sake vs a cat mob and having to build an erector set just to use 3 lug. But whatever, I think this is one more push towards a spectre 9. Keep us updated.
Have you looked in the can with a flashlight to see if any of the baffles have been hit? I'd say the POI shift is due to changing turbulence inside the can based on changing volume when going to a longer configuration. Plus harmonics is probably a factor tooK Sealed had no POI shift at all from unsuppressed shooting so it functions as advertised
All other configurations destabilize the bullets so much not even an Aimpoint ACRO P-2 can adjust down that far. Groupings are at 10-15 yards just to keep them on paper. The K sealed is good at all ranges out to 25 yards
I think I found the culprit, I think the end of the L section of the can is just a BIT off

No hollow point ammunition shot through the L configuration, once I figured out what configuration worked I put about 200 more rounds through the Sealed K and found no evidence of jacket material in that section of the can further reinforcing my theory. I think this is going to have to go back to the mothership
I will keep the thread updated , this one is going straight to the president of B&T USA apparently. Very interested to see how B&T handles this problem.
No discernible damage to baffle stacks , the “transition tubes” from the K to L configuration show copper lines in the pictures above. I am thinking the L portion is not 100% concentric but I could be wrong. It’s weird how the K Sealed works 100 fine with no POi shift but making it L or Flow Through just makes everything go to ****.Have you looked in the can with a flashlight to see if any of the baffles have been hit? I'd say the POI shift is due to changing turbulence inside the can based on changing volume when going to a longer configuration. Plus harmonics is probably a factor too
Sweet so instead of being able to buy the compact for $600 b&t chooses to discontinue and force us to pay an extra $400 for four inches of useless crap.
Looks like the end cap of the cocking tube is preventing it from clocking to a different lug. A perfect fit.. until it isnt...I'm not familiar with B&T cans. I only know of one style of 3 lug mounting. Apparently B&T has engineered something different. Normally with a 3 lug you can clock the can around just like you can with a Neilson piston device
