Not sure which gas blocks I will be needing for my Stealth 2.0 builds and any help is much appreciated

1)  16" midlength gas - 5.56
2)  12" pistol gas - .300 BLK

Also, never owned a .300 blackout before, what buffer weight should I be looking at?  Won't be getting a suppressor anytime soon, so what works best for supers and subs?

Thanks

For the 5.56... 0.75" if it is a Stealth. 0.625" if it is a PredatAR barrel.

0.75" for the 300 BLK Stealth barrel.

I'm not a 300 BLK guru so you'll likely get a better answer from someone else, but I would consider an adjustable gas block for it even if you don't plan to suppress. SLR makes one with set screw spacing to match LaRue barrels.

I use them on my suppressed PredatAR's.
