Or are all Colt ARs banned? 

As long as it is compliant it and not marked AR15 you should be good to go.

Oh ok.

 

Man, just when I thought I understood Jersey compliant ARs...

 

Anyone know if a 6920 is marked "AR15" or if there are any other restrictions regarding the 6920 other than the normal stock, muzzle and lug? 

should be good to go.  pin the stock.  pin a compensator/brake instead of the a2 flash hider, grind off the bayonet lug.  

 

colt lower roll marks on the 6920 are the below two that i know of.

i believe the 6720 is the AR-15 marked lower

I believe the Colt 6920 is marked AR15A4 - no?

good to go once it is made NJ compliant, I own one

I believe the Colt 6920 is marked AR15A4 - no?

as far as i can tell, only the 6720 currently is

The ones iv sold and transferred were marked M4. Before purchasing if its not from a local dealer i would verify. some might have special markings for certain editions etc etc

Pinned brake is fine correct, doesnt need to be pinned and welded? 

2013 Production models are marked  "M4 Carbine"

Pinned brake is fine correct, doesnt need to be pinned and welded?

I'm not quite sure what you mean. Every gun I've seen had a hole drilled through the comp. partially into the barrel. A pin inserted. And welded over. I'm not sure of a different way to do it.

why not just get the colt match target?

 

I have the Colt MT6400 and it is marked M4 carbine on the receiver.  Already made NJ compliant and it's basically a 6920 (as far as I know and from what I was told).  I bought it at bullet hole last year.

relevant ATF documentation for pinning muzzle devices...

brake MUST be pinned per ATF guidelines..

I almost went with that option then I learned that the 6400 has a "neutered" BCG.

The MT6400 does not have a neutered BCG. I have 4 of them, all are full auto bcg's.

Really?  That would actually make things easier for me.

 

Any idea what theyre talkin about in that thread I linked? 

It's possible that the older 6400's had semi auto bcg's, but since 2008 they come with full auto bcg's.

Older 6400 were neutered. New ones are not.

The Colt Match Targets are harder to find than the 6920/6940's.

They are also more expensive.

 

If I had to do it again I would buy the 6920/6940's and make them ban compliant. Probably wind up a few dollars cheaper.
