Good things come to those who wait...Well i guess i will just have to wait than like for every other ar part i need in existence .
Good to know... I was trolling thru the small parts at the shop and came across one of these that was broke... I looked at the internals of the unit and dtermined that it could infact fail fairly easily in a few situations... He went on to say that he saw a few of them break and he needed the smith there to fix them if he even could...Ambi is overrated especially if you shoot lefty. It gets in the way and disturbs your grip weld. I thought I had found a cure but now detest it. Waste of $30.
