Need some help,
I purchased a 9 inch AAC blackout upper for my SBR. The problem is it has a KA URX 3 which weights 1/2 a lb. I wanted to switch it out with a BCM KMR that weights much less but to my chagrin you need a KA barrel nut wrench to get the one off the AAC upper and that thing cost $120!
Anyone near Decatur have one of the KA wrenches I can borrow? If not it might just be cheaper to take the whole thing to a gun smith to do the rail switch for me (looking at you Bryan...)
Thanks
