Defective out of the box! - Pro Mag AR-15 Carbine Stock Wrench/Multi-Tool PM249

I bought this so that I could change the butt stock on my AR. I thought why spend all kinds of money on a high end armorers tool when all I need it to do is loosen a nut? Here is why you should not buy a cheap tool; it is not built to specifications and will destroy the threading on your buffer tube? Only 2 of the 3 pegs aligned with the three slots for the nut!!! Save your money and buy a higher end tool for this job, I regret taking the cheap route!
