Standard or Tactical Muzzle Brake, that is the question

[Disco]

AI experts out there please help

AI muzzle break yes, but is it the standard or tactical version,

I cant screw the cap off as its very tight, so before I ask an engineering shop to muller it for me can anyone ID it from the pics or the 4316 code on the side??

it came with a 2017 AX308

Many thanks

I thought the standard AI muzzle thread was 18 x 1.5mm.. 

Try soaking it in some CLR..

I tried some recently to clean my muzzle brakes after watching a Erik Cortina video and it's brilliant..

Kills the carbon in a few minutes and wipes away  effortlessly..

Brakes are fiddly to clean..!!

Not anymore..!!

I've only used it on stainless brakes not painted ones...!!

That’s the tactical because the front portion is threaded to accept a moddy.

The thread protector on the front, are you unscrewing it the correct way? Remember AI is left hand tightening (anti clockwise), not right hand tightening (clockwise) like most normal threads.

If you’re doing it the wrong way, you’ll be tightening it on ever more, but thinking you’re trying to unscrew it.

Tactical brake to accept the suppressor. Front cap threads anticlockwise, you might be trying to twist it the wrong way

Tactical brake to go with AI MODERATOR 

Hope this clears up any confusion??

This stuff from wildcat moderator s helps to keep the threads from seizing up

What is the silver tube on top of the muzzle brake? Iron sight?

The thread protector on mine is really loose that you can spin it off..

I can't remember now but does it have a grub screw on the thread protector? In the first picture it definitely looks like there's something in the hole...?

I would guess that it is a 3rd party mirage band front post. The AI option is just a bolt. You can fit a front sight in the same hole on the muzzle brake and there is a mirage band that fits each option. Front sight option shown in the link below.

It’s a stainless Allen bolt and nut to fit in the hole but not all the way through to hit the barrel so I can use a mirage band as said above. The thread protector does have a hole in but don’t think it’s threaded. We often do the same with nuts at work to make sure they don’t bind up on dirty threads ( non load bearing) ,easy to squirt some release oil into . The other option is to cut a groove inside the thread protector across the thread s ie front to back with a hacksaw to the depth of the thread this will then clear any carbon out as you put the protector on . A small wire brush in your tool box helps too at the range .

Just looked at the price of iron sights £300 plus for a pair of AW ones . Mirage band from dolphin rifles and a screw out of the bucket in the garage much cheaper!!!
