View Full Version : ISMI spring for AR-15

July 28, 2005, 10:02 PM
I have 2 lowers that have the typical, heavy single stage trigger pull (Stag Arms and Cavalry Arms MKII). I would like to give these spring kits a try. Has anyone else used them? Any comments would be appreciated. I would like to improve the trigger pull without compromising reliability, durability.

The kits inclue a trigger and hammer return spring
