As much as I plan to eventually get some tracers for a couple of my rifles (ar and ak), just because I think they are neat, I would have agreed with most ithers that they are useless in non-military situations, especially in a semi-auto where you dont need them to aim your stream/spray of full-auto fire, until a couple of you mentioned putting them in as an indicator that you are almost out of ammo.I had actually never thought of that, and actually think that is a pretty freakin cool idea! Still dont think is LIKELY to be of any use in a non-military or SHTF scenario (and probably unwise legally in HD due to perception by DA/juries, fire hazzard, etc), but in a Katrina/SHTF/military kind of situation, it does actaully seem like a pretty legit and useful purpose for them in a semi-auto.....
Maybe this was common knowledge to a lot of people here, dont know.I was in the Navy, so I never learned alot of this combat-type tidbits of info.Guess the Navy figured if all the CIWS, F/A-18's and F-14's on my carrier didnt save my butt, an M16 wasn't gonna help, so they skipped all the gun stuff (the upside of that being that I didnt have to shoot anyone, and was HIGHLY,HIGHLY unlikely to get shot at, so it was a fair trade off.....)
