The above account shows that when we modify our firearms things can go wrong. I am so glad that nothing worse happened.
I have used the QUE BOSS style non-threaded installation muzzle brake and the Volquartsen clamp on for 22LR.
I considered others.
The QUE has never budged and never caused a problem. It fixed what it was intended to fix. 223 and 300WSM.
My Volquartsen never budged but one of my shooting buddies did. I found it down range. He had altered it from the manufacturers specifications. Once restored to "as designed and intended" he had no additional problems and it performed as intended.
Things that go wrong can be traced to the design, installation or maintenance.
Many of you know these things but I assume not all so...
- Clamping force and resistance to being dislodged under the force of the braking action.
- Alignment to the barrel/concentricity.
- Projectile clearance.
If any one of these is goes wrong you have the potential for a dangerous situation.
Other than just flat being blown off the barrel because of weak clamping, everything else is a clearance issue.
Clearance of the projectile affects the effectiveness of the brake. The tighter the better the brake will work, however chances in concentricity become more critical.
Alignment to the barrel can be from the manufacturing process not matching the barrel profile properly, poor barrel concentricity
, installation problems such as debris under the clamp, poor concentricity in the manufacturing process or many other challenges. If combined with a tighter than ... clearance, problems could arise.
Another issue with clamp on brakes is of course stability during transport. bumping and bouncing at the end of a long fulcrum (the rest of the
puts a great deal of lateral force on the brake. If dislodged in this way, really bad things could happen.
I am sure that lots of clamp on and similar non-thread brakes are out there, I also believe that many problems are not reported. The ones without problems never get any comments.
IMHO The concept is not inherently bad. Execution is always the challenge both for the designer/manufacturer and the user.
I no longer have any interest in using clamp ons but YMMV
