I've been told of the advantages of the straight trigger, but I may stick with the curved because I'm used to it, and I don't shoot long range well enough that it's likely to make any difference.

The non-adjustable part really doesn't matter to me if it breaks clean at that weight. I have a DIY cobble together I did last Christmas with Spike's lower and plain Jane internals from Palmetto. It could stand with a trigger group upgrade. Might make a very basic rifle into a shooter!Designed by Lantac, manufactured by CMC Triggers, this tactical trigger group is a completely self-contained, drop-in fire control group for AR15/AR-308 rifles. With truly remarkable trigger control, trigger feel, and accuracy, this trigger retains the rugged reliability of a MIL-SPEC trigger group. Trigger pull is factory preset at 3 to 3.5 pounds, and is not user adjustable.
