My Black Hole Weaponry LTM barrel felt a little overgassed when I first shot it with a standard spring and carbine buffer. Shot it back to back with my issued Bushy (16" carbine gas) and didn't see the expected difference in perceived recoil or feel. That changed with the heavier buffer and sprinco blue.
As an aside, I asked BHW what the spec'd gas port size was on the barrel and they replied .085-.088. That seems a little larger than some of the other sizes I've read about here for a 16" middie.
I've been considering trying the VLTOR A5 to see if that changes or improves the feel over my current set-up.
I just read your post. As Gunz said, that GP is WAY too big. Rifle ports start in the .091-.093 range and go up from there.
So, YES, a Vltor A5 system with one of the heavier A5H3 or A5H4 buffers would have a huge impact on how the gun runs. Also, I would consider a Syrac adjustable gas block and/or an LMT Enhanced Carrier. That port is ridiculous.
