Dear guys,
How does adjustable gas systems work? Ex. JP adjustable gas block with a lightened BCG. Do you use a heavier than milspec buffer or a lighter than milspec buffer? Do you use heavier springs or lighter buffer springs? Do you need to play around with the loads inorder to maximize this system? Do you want more powder/velocity or not.
I plan to use a middy 16 inch barrel with a PRI Gen II adjustable gas block and a Young MFg. Lightning BCG. A highly regarded source told me to use a Red JP buffer, unfortunately, I plan on using a Magpul UBR stock for this build. I know that full length buttstocks are more popular in game guns but for some reason I just prefer the UBR. So, I cannot use the red JP buffer as they are designed for fixed A1 or A2 buttstocks only. Rifle will be used for 3 gun matches and rifle comps.
Please give me your comments on how to tweak this system to get the best performance overall. Also, suggestions on which buffer I should use, what spring, loads will be greatly appreciated.
Thank you.
