I have 3 of the HTA cans 2 of the 5.56 and the 308 and I can’t say enough good about them!
I have heard you don’t’ need to clean center fire cans, well after looking at one of my 5.56 cans after 1000 rounds I cleaned it and do it every 500 rounds now, soak it in ATF overnight and brush off with wire brush.
The things I like about the HTA cans are, you can take it apart and you can restack the baffles, any strikes on baffles and you just send the baffle back not the entire can for a new one, just as quite as any can, I really like the ability to change the thread pattern , just put my 308 can on my 223 and shot it side by side with a 5.56 can and could not tell the difference. Oh and the price is ½ of the cost of other cans that you can’t take apart or need adapters for.
I have had no POI shift on my guns and only have seen one shift more than 2” at 100 yards and that gun had a funky muzzle break on it. On an old colt 16” pencil barrel car-15, I shot a 3 shot 100 yard 3/8 inch group with black hills 77gr, and 5 shot that went under and inch. that is now my go to coyote gun.
Waiting on a new barrel for my 243 for the 308 can, then the hogs will pay at 3-500 yards
