Yet the suppressor still don’t make rifles hearing safe. Most still recommend hearing protection. Intrusive ear plugs do make rifles hearing safe. Yes been around 120 years but have become must haves in the last 5
They've become more attractive to buyers in the past few years because the wait times for getting them cleared by the ATF has gone from 9-18 months to under two weeks in most cases, and under a month in almost all cases. They got even more popular when folks began saving $200 on not having to buy tax stamps. Their popularity is going to go through the roof if this non-NFA item thing sticks.
But, the 4 points that UncleHuck stated above are facts...there is less recoil, there is less muzzle blast, there is less sound, and there is less muzzle rise...all of which enhance accuracy.
Can point of impact change from shooting unsuppressed to shooting suppressed on the same rifle? Sure. But, most suppressed shooters don't ever plan on shooting unsupressed again. My rifles that I shoot suppressed are all "set and forget", and I've not experienced ANY of them getting less accurate when adding a suppressor...only more accurate, due to the reasons UH stated above.
That said....buy one, or don't buy one. Everyone has their reasons.
