Issues with the latch locking properly in my ar rifle - Leapers UTG AR15 Extended Charging Handle Latch

This charging handle latch did not work as it was with my standard AR-15 charging handle. Fitment on the charging handle itself is not the problem; I was able to install the piece on my charging handle. The problem lies with charging handle as it functions in my AR. The locking part of the latch itself cannot clear the notch on the BCA upper receiver that is designed to keep the charging handle locked in place when not in use. The reason I am giving it 3 stars and not 1 is that the issue is fixable. I was able to file down the part of the latch in question and now it functions well. Either way, out of the box it should have worked as intended, it did not. On another note, cosmetically speaking the finish is sub par.
