Almost 5 stars - JP Enterprises AR-15 .154 in Small Pin Trigger Kit

Excellent, well made trigger kit. Installation and adjustment were very straightforward. Read and follow the directions and you'll have no trouble getting a good result. The included video was a nice aid as well.

Trigger pull weight was reduced from 7-1/2 pounds to just a tick over 4 pounds with the red spring. I opted for certain ignition rather than minimal pull weight. Take up, creep, over travel and reset were greatly reduced. The only reason I didn't give this a full 5 Stars is that trigger creep was just a fraction more than I consider perfect. The actual amount of creep is minuscule, I can just barely feel it move before it breaks and that's paying careful attention while sitting in my chair. On the firing line, it would probably be undetectable.

One suggestion I will make is to only use the red Loc Tite on one end of the pins and the adjusting screws and use blue Loc Tite on the other end of the pins so you can someday remove the set up if you want. The red Loc Tite can be heated with a torch if you want to make changes, but who wants to torch their whole receiver? If you are careful the adjusting screws themselves can probably be heated enough to release the red Loc Tite for additional adjustment without affecting the heat treatment of the hammer and sear. Probably won't be necessary, but as I said, I'm picky and also cautious.

Overall, I like JP's approach to their design and installation. If a part can fail it will and JP obviously doesn't want failures. Very solid piece of work.
