I did the yellow JP springs and polished my stock trigger parts. I was very happy with the results and thought if the springs made this much of a difference then the full EZ kit has got to be awesome !!!! It does give you alot of adjustment capability , but feels no better than adding yellow springs and about 2 minutes with a dremel and a polishing wheel to the stock trigger. I ended up leaving the stock parts and yellow springs in my 15-22 and put the EZ kit in my 15 PSX. If you have the $250 burning a hole in your pocket and nothing else left to buy then go for it....... If you want to be just as happy and still have $237.01 to spend on ammo and targets then go with the springs. Hope this helps you out.

Fit and finish on the kit is perfect..... no modification is needed if you decide to go that route.
