Pics added. Thanks to everyone for your help!
Got a question for you experts. Having an issue with my FA. Getting short stroke issues. Running a 11.5" upper, with carbine length gas tube. Having issues with 55 grain .223.
-Failure to lock back after last round,
-Will pick up next round, but gets stuck when the bolt is half way home.
-Tried H3, H2, H1, and standard Carbine buffer.
- upper and bolt are well lubed.
-replaced gas block with new one, checked alignment
-gas rings on bolt are good/not worn.
-no leaks in gas key
-i've tried different size buffer springs. Even shortened one by 2 coils. But started to get bolt bounce and FTF.
-x193 works well for the most part, but not 100% reliable.
- have tried different mags.
Any suggestions? Thinking about swapping out the DI system to a piston conversion. Piston conversions work well with FA?
Thanks guys!
