98Z5V Posted February 24, 2015 Report Share Posted February 24, 2015 Good news on the cycling now - but that means the gas port size is off. I went through playing with the buffer weight only because I didn't want to rip the upper down and drill the gas port up. Playing with the buffer weight did two things for me, and I knew that going into it: 1) easier than ripping the upper down. 2) if it cycled lighter, it would confirm that my gas port size is too small. One day, I'll rip the upper apart and drill that gas port up. <thumbsup> Quote Link to comment Share on other sites More sharing options...
Magwa Posted February 24, 2015 Report Share Posted February 24, 2015 Ok just so I was not talking out of my A$$ I just pulled my buffer it weighs 5 0z it is a solid buffer,,,, I have shot both supressed and unsurpressed 147, 187, and 220 and have never had a issue of any kind.... so I am thinking 5 oz is not a H3 so if I said the wrong thinmg my bad but I am still learning too.... my barrel is a 10 1/2 pistol lenght gas tube now one thing I know will help if you are short on gas is a pigtail gastube it has extra lenght and will capture more gas as i understand it ... maybe?

392heminut Posted February 24, 2015 Report Share Posted February 24, 2015 I don't have any experience at all with the pigtail gas tubes but the general consensus over at 300blktalk.com is that they create more problems than they solve and really don't work for the 300 platform.

.308LiteHunter Posted February 24, 2015 Report Share Posted February 24, 2015 (edited) I'm going to try running a couple different buffers with NEMO's 300 Blackout spring. http://store.nemoarms.com/300-blackout-custom-carbine-buffer-spring/ Edited February 24, 2015 by .308LiteHunter Quote Link to comment Share on other sites More sharing options...
NTXshooter Posted February 24, 2015 Author Report Share Posted February 24, 2015 98, what size should the gas port be? .308, i haven't tried supersonics yet. I didn't have time the day I was at the range. Next time. COAL on that load is 2.260" Quote Link to comment Share on other sites More sharing options...
98Z5V Posted February 24, 2015 Report Share Posted February 24, 2015 98, what size should the gas port be? Minimum 0.090". Shibi builds his pistol-length barrels with 0.100" gas ports, I'm pretty certain. Quote Link to comment Share on other sites More sharing options...
shibiwan Posted February 24, 2015 Report Share Posted February 24, 2015 Minimum 0.090". Shibi builds his pistol-length barrels with 0.100" gas ports, I'm pretty certain. Yes, also depends on gas system length, but you can get away with 0.088" or bigger in a pistol-length system. Quote Link to comment Share on other sites More sharing options...
