I have a less than 16" AR that has a permanently attached Vortex Flash Hider installed to bring the total length to 16"'s. I have a Gemtech suppressor that I'm pretty sure will not attach to the Vortex. If I put the standard birdcage flash hider it would be less than 16"s without the suppressor. What are my options for moving the suppressor from weapon to weapon without being in possession of a SBR? I suppose I could permanently attach the suppressor but I'm not sure how you would clean or maintain it. Any thoughts?
