Just a little added info about Rifle Basix triggers. I installed one and a few years later, swapped stocks. During the swap, I "dinged" an "E-clip" on the trigger assembly which eventually caused the trigger to malfunction, (but NOT fire). The damage caused was entirely my fault. I called the guys a Trigger Basix and asked if they would SELL me an E-clip. They shipped out a repair kit (with additional parts) EXPRESS post that day. I received it within a few days at NO CHARGE and they emailed me all the info for installation. A nicer group of people to deal with would be hard to find, they really stand behind their product. I couldn't give more praise to their product (I really like the trigger) or the company. Best of luck.
