Hi, I got AR upper with the muzzle brake pre-installed, could anyone suggest me place I could got to pin it to be NJ legal after? Thanks!

By pre installed is it just spun on the threads ? Are you able to remove it, by hand or wrench? If it was pre installed its most likely already welded on, and can’t be removed. If it can be removed any FFL local to you that does any kind of gun smithing should be able to help you out.

I got it from the free state company internet page, no it is not pinned/welded. I just need someone in NJ who can do it quick and correct. Please suggest some place.

Don’t know where your at in NJ. I had Steve at Monmouth Arms (http://m.monmoutharms.com/)

do my compliance work. He’s a vendor on the forum. Good work reasonably priced

I’d check the vendor list and see who’s close to you and give them a call about pricing turn around time etc..
