Looking for a 5.56 caliber 1/2 x 28 thread Silencerco A2 Birdcage that works with the ASR mount. Would take multiple units and pay for shipping. Pic below of what I'm looking for, I am not interested in the 3 prong flash hider, but have some brand new ones I would trade for this birdcage version. Also interested to here about your experiences with this ASR A2 birdcage. Please pm me. Thanks for your consideration.
