I opened up the gas port on my Aero Precision M5.... it was running flawlessly while I had it set up with the Yankee Hill flash suppressor/ Superlative arms adjustable gas block, 16" Wilson combat Recon barrel / JP polished spring and 3.4 ounce buffer weight.... I had the adjustable gas block 25 clicks from zero (at 18 clicks, the Superlative arms gas block is fully open... added 7 more "bleed off" clicks to reduce gas).
Then, I purchased an AMA lil bastard muzzle brake. The brake works great, but it threw off my gas setup... it wouldn'tcycle... I clicked back to 18, fully opened, and it was still short stroking.
So, I came home and drilled out the gas port from factory 5/64" to 3/32"...and, holy cow!! Now it's overgassed! Even at 40 clicks, full bleed off, it seems just a bit overgassed.... and, that's with a heavier 4.4 oz buffer weight.
So, that's no good because if I ever run hotter ammo, now I can't adjust any further...
Therefore, I just purchased an extra power orange Sprinco spring and a 5.3 oz weight.... I'm hoping this will bring it back to equilibrium... allowing some tunability... but, I should've just taken my 5/64" drill bit and wallered out the hole just a smidgin.. now, I've got too much gas running through the system...
Parts arrive in a week... hoping for successful results 🤙🤙
What do y'all think about all this??
