I ordered a tac latch for my target AR but then I sold the AR itself in the meantime... so now I use the tac latch on my 11.5" unit.
Doesn't really benefit anything IMO... and using it with just the left side just puts too much sideways force on the charging handle. I can see it bending or breaking like that.
I bought it because I thought it would resolve the issue with scope clearance, but I don't know if it would've helped much in the end.
