I have an unused AAC Blackout 51t flash hider in 5/8" x 24. It is new, unused, still with the original shims and rockset that it came with. For some strange reason it is in an AAC brake package, but it is a blackout, three prong 5/8" muzzle device.
I am seeking an AAC 51t 1/2" x 28 blackout three prong flash hider. or $90 paypal will get it shipped to you in the ConUS.
