In my opinion the the back over the barrel / Reflex suppressors do not serve a use as well as modern high quality front mounting suppressors.
For both optimum sound and flash suppression, the baffles situated in front of the muzzle achieve more performance than the expansion tube / chamber rearwards. You also do not see the best flash suppression from a suppressor that adds little length.
Just looking at the sound suppression, smaller / modern front mounting suppressors can be as good or even better than some of the back over the barrel suppressors. This applies to both civilian/hunting rifle suppressors and MIL/LE suppressors.
So in essence a lot of that back over the barrel length and weight is wasted space and weight, if not utilized in a more complex form for a lower back pressure.
In which case the suppressor can get heavier and more complex.
We do have a pretty long history with back over the barrel and front mounting suppressors. Our company has manufactured since 1994 the Reflex supppressors for a another local company, in addition to having our own products lines. The term Reflex on suppressors originates from here.

Ase Utra sound suppressors
Hi,
I painted with a pretty wide brush in that comment,
Not all small suppressors are as effective as they could/should be and not all large suppressors either.
Depending on the design, some back over the barrel suppressors are utilizing the rear section better than others, but looking at the size vs performance differences, in many cases the gain from the rear section is not great enough to make it worthwhile.
Based on our testing and also independent tests, we can pretty honestly say that our front mounting models have some the best size vs. performance ratios on international market.
Looking at our models, the small SL5i suppressor is probably the smallest suppressor on the international market that brigns the SPL below 140 dB at the shooters ear on a .308 Win rifle. This also happens to be our sold model in general to hunting use = Good suppression but in a very small size and light weight.
However we do have the longer SL7i variant or the jet-Z COMPACT in the other family if the user is looking fore more sound suppression and understands that the suppressor is a bit larger / heavier.
Several European civilian & hunting rifle suppressor manufacturers offer primarily back over the barrel suppressors, some of their claims being better balance, suppression etc.
However when looking at where most of the weight is, it is at the front and we have done comparison tests etc. with the balance points and the difference is neglible sometimes ( the back over the barrel suppressors can be easily heavier than our lightest front mounting ones )
We have not necessarily countered this online etc. as much as we could have done. So companies of course have their own philosophy and way of making suppressors, but is it necessarily always as good overall as they claim, that is another story.

I always wondered about reflex cans too, it's one of those things that make sense intuitively but doesn't in practice. I'm guessing it has to do with the fact the gas coming from the muzzle in a tight cone is in turn vacuumed through the rest of the suppressor as the bullet passes through. So the reflex part doesn't see much action.
I can only guess that's it because when KAC changed the M110 suppressor, they went from a long reflex can to one that's half as long and weighs half as much and has exactly the same if not better suppression. Army also did away with the Ops Inc can and everyone that has one says they sucked.
Kinda makes you wonder though, doesn't it? Military fielding shit that could have been proven otherwise by civilians on the internet doing simple side by side comparisons?

Your speculation on Ops Inc cans is inaccurate. Not only is it the first time I've read a negative opinion of those cans it's also contrary to my personal experience and everything I've read posted here by professionals who have used them.
Ops inc doesn’t make suppressors anymore because Phil died and the company went out of business.
Your statements are completely devoid of fact.
I’m aware of that. I meant to quote strykervet.Ron Allen always did, and still does make the 'Ops 12th Model' only it is now the AEM5. When Phil passed, Ron started a new company; Allen Engineering, but name aside the product remained almost identical. Not sure what you're referring to specifically, but thems the facts.
