I am currently using the Area419 Hellfire system for mounting cans on my rifles.
But, now I want to be able to run a can on my FALs and there is not a Hellfire adapter for the barrel threading on the FAL. (9/16-24 LH Facemount - yes, left-handed and facemount).
I have found Plan B and ASR muzzle devices with the threading I need.
What I like about my Hellfire setup:
- It is MINIMAL weight added to the overall configuration.
- It adds less length to the overall configuration than the others - because the rear of the can actually overlaps the end of the barrel by the height of the Hellfire adapter. Instead of a muzzle brake extending into the can, it's the barrel itself extending into the can.
- Cans thread onto the Hellfire muzzle device left-handed. So, for most rifles (the ones that are RH threaded), there is no chance of loosening the muzzle device when you go to take the can off. Removing the can is tightening the muzzle device.
What I don't like is that there is nothing in the Hellfire setup to keep the can from starting to unthread itself (i.e. get loose) while shooting. You just have to screw it on really tight - which risks starting the muzzle device coming off.
I'm also not super-thrilled that the Hellfire setup doesn't leave a muzzle brake or flash hider on the gun when the can is removed. It looks a little goofy with the can off and it also does not give the presumed protection of the can's blast baffle that comes with having a muzzle brake inside the can when mounted.
My brother has the ASR 3-port muzzle brake on all his 7mm and 30 cal rifles. One of the things he likes about it is the ratcheting/clicky lock thing that goes in the can, so he never has to worry about the can starting to get loose while shooting.
But, I don't like how much weight and length that setup adds to the overall configuration. And, it is expensive. And I'm not even sure I can get an ASR mount for my TBAC 338 Ultra can.
I like Plan B for how universal it is. And that you can get it with an integrated muzzle brake for just about any rifle. And there are now recessed muzzle devices that give an overall length that is basically (for practical purposes) the same as using Hellfire. E.g. from Comstock Armory.
But, the thing that still concerns me about Plan B is there is no way to "lock" the can onto the muzzle device so it can't come loose while shooting.
Is there?
And also I don't like that removing the can also twists the muzzle device in the direction of removing it as well. Isn't it pretty easy to end up with a can that is carbon-locked onto the muzzle device and removing it ends up spinning the muzzle device off?
What are y'all doing to ensure your can doesn't start to get loose when using Plan B?
