Hey everyone, hope you have all been well.
Builiding a "Micro" .300 Blackout Upper and trying to make sure my buffer weight/spring combo is best out the gate.
I plan to run mostly supers until I can get my hands on a can but shooting both is in the agenda.
I do have a basic adjustable gas block, but didn't think it should be the only variable I should use to tweak the gun.
CORRECT me if I am wrong, but I figured both sides of the system should be tuned if possible.
Its a 5" .300 BO barrel, micro length gas tube and will sport a Midwest Flashhider.
I am thinking an H2 or H3?
I have run Carbine buffer/spring on most 5.56 I have. 8.5" which was a little rough, needed tweaking or heavier buffer to mitigate that but ran. 10.5", 11.5", 12.5" 14.5" and 16" all run fine on the Carbine Buffer/Spring combo.
Once this .300 is done, I am going to look towards a getting a can for all the AR's.
It's my last build for a long time.
TLDR;
Whats the best buffer/spring combo for a 5" .300 Blackout build?
Which combo for Supersonic?
Which combo for Subsonic?
