Buffer Spring question for the AR Gurus

[imyomama]

This is a video on the SFAR. Skip to the 14:18 mark for information about running different buffers in this gun. https://www.youtube.com/watch?v=FcXM5SXjVFg

that was an interesting video ... thanks for that .. i'm actually in the market to buy a 16" sfar so i'll keep the h2 buffer in mind ..

as far as the op is concerned however , i think he's still SOL.

shooting subs with a can with the 3 ounce buffer and assuming on gas #3 which is the most open. ... if that doesn't cycle reliably , the only thing left is to pull the gas block and drill the port hole bigger ..

that will definitely void warranties and probably make setting #3 unsafe with supers ...

i still stand on 300blk being a much better choice for 30 cal subs ..

Yep wrong gun for the application. If your intent was to shoot subs and almost if not only subs 300 blackout is what you should have gotten.

There’s really no point to shooting subs in a 308 because they kinda suck at it. The 300 blackout is a much better purpose built cartridge for this.

Sorry OP, I doubt you will ever get it to cycle properly with subs.
