Thread: Muzzle brakes, Suppressors, and Accuracy

I agree gadgetman. I'm just saying what I have found. I'm not praising my own products, just my experiences.
Suppressors now have brakes incorporated in their design so they will be more efficient than a brake alone.
I know Robbie's suppressors work well and am aware of how much h any rifle flexes on firing.

Any form of reducing recoil will improve groups.

Suppressors reduce very little physical recoil compared to a decent ported brake.

And yours are awesome brakes

Deviating off-topic somewhat I know, but these are interesting comments: could you please explain to me the physics of any enhancement in recoil reduction from having a "muzzle brake" internal to a suppressor beyond the spreading in time of the gas generated impulse with an associated reduction in intensity that is inherent to a suppressor function in standard configuration?

The basic principle of operation in any muzzle brake (whether or not it is in a suppressor) is that a series of faces at right angles to the bore are impacted by the rapidly expanding muzzle gases, tending to push the rifle forward which counteracts the recoil to some degree. In some semi-auto actions, this forward pushing force (combined with a different gas pressure curve) can short-cycle the action and the rifle needs to tuned to function properly after suppressor installation.

As soon as the gas exits the muzzle brake ports it is pushed back into the suppressor or cover mitigating any forward thrust.

I tried muzzle brake covers years ago to try to reduce noise & blast, miserable fail, so I canned the idea.

There are a number of videos on the net showing this using muzzle brakes with a suppressor or cover placed over them before & after recoil comparisons on an AR 15.

I have done a couple using bigger calibres.
