I was switching stocks today on my t3 and went to put it in a krg bravo and my safety didn’t full go on the safe position. Took it out of the stock again and saw this little piece fall out. Looks like it’s for the safety so it doesn’t come out of trigger mech. Has this happened to anyone before? I tried putting it back on but it’s pretty damn hard and don’t want to force it to much. Any recommendations?
