Would not thread - Breek Arms BFO Flash Hider Cage Style Outside Threaded Muzzle Device

MuzzLe device would not thread onto barrel when I tried to install it. To be sure it was the muzzle devices fault and not the barrel, I tried it on a buddies 9mm pcc which had the same thread pitch and it wouldn't thread onto that either. I was very disappointed as this appeared to be the low budget answer for a flash hider and I was sorely mistaken. Based on this experience, I cannot recommend anything made by Breek arms.
