So I'm wanting to get 2 Geissele triggers for 2 ar15's i have. One is an 18" "precision type" type AR. The other is a 16" carbine (all around use with acog). Now I've pretty much decided on the SD-E for the precision AR (unless y'all have better ideas). But, I'm in between the SD-C and the SD-3G for the carbine. Will i be better off using the SD-C for an all around carbine, or will i really like the SD-3G. I know Geissele doesn't recommend the SD-3G for really anything but 3-gun, but it seems like a real popular trigger online. The carbine currently has a 3.5# timney. The 18" has a factory mil-spec trigger. Just trying to make up my mind before i order 2 triggers. Thanks for Your time.
