I blew up my Colt M4 a few months ago, and decided to make a dedicated .22 upper out of it. Its been functioning flawlessly, thousands of rounds of Winchester and Federal, including HP's. The only complaint I have is that the trigger is still very "colt-ish" and needs to lighten up.

I understand that Timmney and Geissele make options as far as a new trigger group, but I was wondering if I got a new trigger spring (JP, Wolff, etc) if it would cause any problems? I do not want to put another $250 into the gun, especially on a trigger.

Actually you could experiment with bending the legs of your current springs to lighten the force applied by them.
It'll take a little patience but won't cost a thing to try.

Good luck,

TACCOM3G's new firing pin and the pressure plug should take care of any issues with lighter triggers.

I run JP yellow springs and a modified hammer (tail milled off)  in three 22's and have never had any problems and with Tim's firing pin and pressure plug you should be good to go.

I have done the spring bending thing on three or four rifles now all with good results. I did have to "tune" the bend on one of them but its such a quick and easy job its no sweat, and as Dave mentioned, no cost.
