I had to take something thin and knock that little ripple down for mine to close. Also heard moving the bcg backwards or something does the trick.
An Ambidextrous Safety Selector is slated to be "Coming Soon" from Partisan Triggers.

Partisan Disruptor had a patent for this trigger before Rare Breed came out with theirs. Your question should be; did Rare Breed copy Partisan Disruptor? This is a drop in trigger, it doesn't matter if it's similar to Rare Breeds.
It’s not working with mine. Looks like I will need to cut a notch in my bolt.
You are probably experiencing bolt bounce. Go to an H3 buffer.
Tony might have hit on something, Olympic Arms almost always came with AR15 carriers, needed a FFL to get M16 cut carrier from them back in the day. You will need a M16 cut carrier (standard nowadays) and a H3 weighted dead-blow or reciprocating weights buffer.
Doesn't come with a buffer ... that's why reference to needing an H3 weight buffer is made in the product description. Also, this won't install in a lower that doesn't have a low shelf like most Colt'
I had a problem with my trigger and emailed Partisan and they replaced it with a new trigger
lol @ Tony. The standard rifle buffer is 5.0oz, H3 buffer is between 5.0 - 5.4oz.. With a M16 cut carrier, 5.0oz buffer, a lower that allows proper fitment of the FRT, this should work for you.
It will not work with a standard M16 3-position selector, but you do not have to use the Partisan one either. Datum Machine and KAK both sell a standard M16 selector that has been modified to work with FRT triggers (including the Partisan) for about $30. I like the look and feel of the factory selector over what the Partisan trigger comes with.
