hello all, new member here. . . after doing some research i have learned that "trigger kits" from different companies are a bad idea for these carbines. After going through pages and pages of mostly arguing and insults lol . . . . it actually did lead me to one legit question. Do the stock springs ever weaken to a point to where they can fail and cause these carbines to run away? And if so, is there is a certain point of wear or certain round count fired through the gun before we should be replacing these springs?? ***I know this topic gets a little touchy when its brought up. . so just everyone is clear. . this question IS NOT in regards to aftermarket sear springs, trigger kits or whatever anyone wants to call them lol .. but for the factory spring itself*** Thanks in advance.
