which comp for 9mm PCC ?

That looks like a very good design... just ugly as crap.  It has the proper thread pattern too. Aluminum should be lightweight.  I think the new TACCOM barrel with an MBX brake would make a good pairing, actually.  

Man, you're right about ugly.  So ugly they don't even put it on their complete barrel they sell, opting for a more rounded design there, that they don't sell by itself.

 

It looks like a Glock slide that went through a Limcat mill job.

Part of the reason I believe MBX made the comp smaller on the barrel they offer is because the original one would have been to large to pin to the barrel and still be able to get the barrel nut over it. The original is like 1.25” tall. MBX does offer the smaller brake separately it’s listed under the pin and weld service.

Just found it... MPX threading only.  Ugh.

If you need 1/2-28 threading and you’re willing to do some work on it and have access to a drill press, the $50 Surefire Procomp for 5.56 guns works fantastically.

 

Drill the center out to 3/8” - which is easy on a drill press, given the precisely machined .223 pilot hole.

 

Then simply enlarge the first two ports facing upward slowly with a cordless drill at the range, until the gun shoots flat. 

 

(I have to credit Zack Smith and Max Leograndis for this idea. I’d never have thought of it.)

 

Here’s where mine ended up:

I don't see side ports on a 9mm comp being useful. To me to utilize the small quantity of available gas, an effective 9mm comp. would only have top ports. I have had good luck with this one.

I put one of these on my MPX after going to a lighter handguard. Its been fantastic.

You could always get a thread adapter from KAK they have a 5/8x24 to 1/2x36 and such. I found them on eBay earlier today

Thx for vid. I have one of their brakes for a 5.56 and I have been impressed with it. The price/quality ratio is high.

thinking about changing the comp on my 9MM PCC 14-1/2" Fortis tapered  barrel  … any recommendations  (brands)  ?   looking for less weight up front.... 

 

Why are you unhappy with the Fortis brake?

 

It looks similar to the FSB, but it also has two vertical holes...  Thinking that it might reduce flip more than a simple brake.

Can’t go wrong with a sub $80 brake/comp, especially when they keep having sales!

not really unhappy with the Fortis … just wanted to find a lighter brake/comp .. to reduce the weight at the end of the barrel...   

   I decided on the Venom Defense titanium 1/2x28 comp...  according to their website it weighs less than one ounce... 2" long... .75" high..    .95" high...  & right now its on sale for $72.98 delivered …

For a PCC? I'm no rocket scientist but I do know that I want all available gas pushing the muzzle down, to me all the horizontal ports are just decreasing that effect.

Yep, horizontal are near useless for a PCC.

We made one that I shoot my Open pistol loads with, (1850 fps ) in Run N Gun matches. That is fun.

He didn't have the pic up when I posted that. The Cannibal on his website is different.

You planning on making the one pictured?

I have looked at this set up myself, for my next build.

Mostly because of the length needed

You're fast looking that up

We also make the Cannibal for the AR15  - installed on a $499.00 only addition was, a binary trigger (too slow ) and our brake straight out of the box , not even tuned yet.

Cannibal - an animal that eats its own species.

I have a UM Tactical and a Foxtrot Mike comp.  Check out the Foxtrot Mike comps at either Brownells or Primary Arms.  Great comp for the price.  May be listed as FM Products for your search.

Just installed a Venom D&D comp this afternoon.  Can you share any particulars on your ammo?  Thanks.

On the subject of comps... Taccom released their new CF sleeved barrel, but it's 13.5".  That's going to need a comp at least 3" long to pin and make it legal.  It's also 1/2x28 threaded instead of 1/2x36.  Anyone have an idea of what comps are long enough to work, with that threading available?

Here is a pic off their FB page last night.

They have made the new one, and can pin and weld for you.

 

I may have to try one

Unfortunately they aren't doing a ramped barrel version
