I have a brand new open package Q Series Cherry Bomb threaded brake for using a suppressor.
It is 9/16-24 which is most common with standard M1A barrels.
It has never been mounted, I just ordered the wrong one without realizing my specific barrel is 5/8-24 thread.
Photos shows it next to one of my other ones that is mounted.
Located in the Waco area but don’t mind shipping.
$65 pickup
$69 shipped.
