Hey guys, took a new 13.9" mid length build out last night for a function check and ran into some short-stroking issues using ammo and mags that have never caused problems in the past. Also tried running two different lowers, one that was a standard carbine with an H2 buffer and the other is a new A5, in which I tried both an H2 and H1 buffer to the same effect. I was getting bolt over bullets malfunctions at first, but after blasting through a few boxes of ammo it is now just a won't lock back on an empty mag problem.
I have read through the flurry of posts made here on this issue, both active and archived, along with watching quite a few YouTube videos on the subject and I have a pretty good idea of all the things that it could be. So starting from the cheapest/easiest option, I was thinking about going with a lighter spring, with the choices being either the TTI Ultimate Light-Speed buffer spring or a Tubbs Lightweight flat wire spring.
Again, I am aware of all the things that could be causing the issues, and for the sake of sparing us all redundancy and re-hashing the same stuff over again, just looking for input on whether these springs have solved minor short stroking issues for under gassed rifles, or if there's even other spring options that may work.
Thanks
