Gas block? URX ii

[shadow6492]

Anyone know what gas block will fit under the KAC URX ii midlength rail? 11.5" barrel with .075 journal.
thanks

I'm not familiar with the URX ii, but is there a reason to believe that any of the standard low profile gas (BCM, Seekins, Rainier, etc.) blocks are too big?
