A suppressor that walks loose after a few mags can throw off your accuracy and ruin your shooting rhythm fast. The best cans stay locked down even after long sessions, keeping your point of impact consistent and your rifle running smooth. Design, mounting systems, and material quality all play a role in how well a suppressor holds up under heat and sustained fire. If you want something dependable that won’t back off halfway through a range day, these options have proven they stay put where others don’t.
