The rod doesn't come with a spring so I took the one off my stock. I wish it came as a truly complete kit where I could just take the old one out and stick the new one in quickly.
Aside from that, it performs as promised. Great upgrade if you don't want to drop the 100+ on TechT stuff.
If I could go back, I would have bought the Lapco just because I think the outside material is smoother preventing too much friction when cycling. I still like this one though and don't intend to change it out. Still a solid choice for those of you that can walk the trigger up to 20 - not likely - and those that have Etrigs
