FREQUENTLY ASKED QUESTIONS

 

When selecting a caliber for one of our muzzle devices, the correct choice is based on your cartridge's actual bullet diameter. For example; if you have a .300 Win Mag, you would select a 7.62/.308 muzzle device. This is because the bullet for that cartridge is a .308" diameter. For a more detailed explanation and examples, check out our Caliber Fit Guide.

Measurable performance between the M11 and M41 is very similar. Both will drastically reduce recoil, as well as mitigate muzzle rise. As for features, the M11 has a closed bottom which will prevent dust and dirt being kicked up after every shot. The M41 however, is radially ported which will exhaust gases in each direction. For bench shooting this won't matter much, but is something to consider if shooting prone. Because of its top ports, the M11 will need timed properly to ensure the they are oriented correctly. Conversely, the M41 simply needs torqued to spec - no specific orientation required.

    I'll make this short and sweet. I'm not a fan of overpriced muzzle devices. This is not one of them. It is well made, looks great, works as expected and I will definitely purchase again.

    M11 SEVERE-DUTY® MUZZLE BRAKE

    Posted by Daniel V on 25th Sep 2023

    Well what can I say ! It’s very sexy looking great color and material … the only that disappoints me It’s that you have to buy the rings and tool to tighten the muzzle into the barrel .. I get the tools but the ring should come with it or at least let the customer know you should place an order for it … but then again this is my opinion

    Quality. Performance.

    The PA M11 brake is very well made. Recoil was considerably less, quicker acquisition. Also, their communication is just as good. Can’t recommend this company enough.
