Rifle is an Armalite DEF10, 16" .308.
I would like to put a dual lok flash hider on it, ideally. However, I've had an issue with it trying to put on the AAC 3-prong in the past; the one I tried at least did not have long enough threads to make it, and bottomed out on the front face of the barrel long before getting to the shoulder.
I'm measuring about ~.79" of threading between the front face of the barrel, and the 90 degree shoulder.
Will the "normal", or long (or any) Dual-loc muzzle devices fit on the end of this barrel?
Thanks
