In light of all the pricey AR trigger options out there and a constant request for a "cheap" trigger improvement has lead me to become a fan of spring replacement coupled with some polishing of sear surfaces (no grinding). However...
JP enterprises casually suggests removing the J-spring in the stock hammer when using their over-sized anti-walk trigger and hammer pins. The reason is that on some hammers the j-springs will bind on the over sized pins. After looking at hundreds of mil-spec hammers I've come to recognize the mark of quality components. Indeed, they are not all created equal. A good barometer is money, getting what you pay for. The J-spring was not intended to be removed and with some bad advice was told it could be purchased without the spring installed...I just don't know where that is.I believe JP's pins were intended to be installed with one of their hammers (built without J-springs) and really question thier instructional advice regarding J-spring removal on a stock hammer. My older, wiser cohorts tell me to replace instead of modify especially for duty. I've removed a handful of J-springs but did not feel confident putting it back into a duty rifle and only did so in an effort to perform an inexpensive "stock" trigger job for a target gun. Sometimes it was not necessary as there was no binding (looking through the hammer pin hole J-spring was barely visible). The same combination of sear compound, springs, and parts differs from one group of parts and it's parent receiver from another...there is no formula, only the basic guidelines for mods and of course function(test, test, test).
Would love to hear from all you AR-15 gunsmiths out there, especially California AR owners who are seeing some exciting new stuff designed to get away from the mag lock..........Thanks!
