Its pre ban, so you can put anything youd like on it.
Well, pre-ban has nothing to do with 922r compliance, so this statement is incorrect. However, a muzzle break is not considered a 922r violation requiring the corrective action of replacement parts. A flash hider is, a muzzle brake is not. In many cases when adding such a device it is important to consider how the state of NY defines which is which. There are plenty of other threads on that though, so I won't get into it as technichally the device you have pictured would be considered a muzzle break.
However, I would highly recommend against using that device, even if just the looks were the point. Reason #1: I have seen example after example of these simple pin on breaks becoming even slightly misaligned and wind up getting tagged by a round. Often sending the device downrange, spattering metal, and possibly damaging the firearm. I can't say if that particular device has tight enough dimensions to the muzzle diameter to have that happen , but either way that leads me into.. *drum roll here* Reason #2: It's a showpiece, and it doesn't do anything. Much the same principle as I discussed in
a recent thread here of bushing comps on 1911s, the physics just aren't there. It's a little different in the case of the 1911 because of the tilt barrel design, but basically still this is a non chambered extension of metal with some holes on the top, thus there is no significant baffle and gas redirection. It's a cheapo useless part for mall ninjas that is actually potentially dangerous. My opinion, others may vary.
