Muzzle brake installation question

[aplus1234]

I'm considering upgrading my stock muzzle brake using a barrel thread adapter to fit the new brake.

Is is just as simple as unscrewing the old brake and adding the adaper and new brake? Is there anything special I need to know for the install? Special washers? Torque settings?

What are the pros and cons of using an adaper as opposed to chopping and re-threading?

Why are you not wanting to use a brake that is cut for how your barrel is threaded?

Without more information about what you're attempting its hard to say. I could see a few issues with your plan. Mainly I'm not sure how you're going to time the brake if you don't have a shoulder to torque against.

Tell us a little more about what you're trying to do and what thread patterns you're dealing with.

What rifle are you trying to replace the brake on? And why not just get a properly threaded brake?

I have a sig mpx 9mm, so the thread is not really standard. I think the adaper I need is this.

The mpx is Female 13.5x1 LH
The adaper will change it to 1/2x28 RH.

The brake that I want is has a 1/2x28 thread so the adaper should fit the bill I think.

You have 3 options here.

1. Use a crush washer ($2)
2. Use a peel washer / washer set ($5-$20)
3. Get it timed from a gunsmith (approx $20)

If you go with option 1 or 2 all you need is a wrench. You just keep twisting it until its on correctly (lined up etc).

A 60$ thread adapter to install a MB on a 9mm that has little to no flash signature or significant blast when fired is not cost effective, nor logical.

Glad I wasn't the only one who was thinking that.




OP, I'd look for brakes threaded for that or get an unthreaded one and have a gunsmith thread it rather than using the adapter.

People illogically spend large sums of money for cosmetic changes all the time on all manner of hobbies.

What makes it double redundant is the same company that sells the $60 thread adapter the OP mentioned also sells a muzzle device that is the correct thread for the OP's MPX for $50. I tried to do the math and it just doesn't compute.
