I own an NJ-compliant "post-ban" Bushmaster M4 carbine with a permanently attached "Izzy" muzzle brake. I'd like to install a GG&G 1297 flip-up front sight gas block on it but the old front sight block will not come off and the new GG&G block will not install because of the permanently attached muzzle brake which is a larger diameter than the barrel.

 

Is there a gunsmith in NJ that can remove my permanently attached muzzle brake, remove my stock front sight block, install the GG&G flip up front sight gas block and then install an NJ-compliant muzzle brake? This must be a muzzle brake, as flash hiders are illegal in NJ.

 

I can send the upper to ADCO Firearms to get it done, but I'd rather give the business to someone in NJ.

These guys can do it.

I ended up going with ADCO. They're in Ohio which is much closer than California.

 

Thanks for the response.

When it gets back, please let me know how it turns out. I'm looking in to swapping out the muzzle brake on mine (it's pinned and welded on), and I am curious what they charged you for the service and how long the turn around time is.

 

When you get a moment please let me know - thanks

Since my original pinned/welded muzzle brake will be destroyed in the removal process, I purchased a Troy Industries Medieval muzzle brake to be installed.

 

My entire upper minus bolt carrier group and charging handle is being shipped out tomorrow. I'll let you know of quality and turn around when it's completed.

ADCO is the way to go. Steve is a good guy and his work is top notch. Turnaround time is always less then two weeks too.

+1 Steve Adco is the way to go.
