GET IN YOUR BUBBLE!
I've read the middy is more "forgiving" than the carbine with carbine buffers: the middy is said to run O.K. with stock or H buffer, whereas I've read here that the carbine gas system should be tuned with the H, or in some cases with H2...
Which leads me to ask, since I'm one of those "But Why?" guys...
Considering the rifle buffer is so much heavier than the carbine ones, WHY would an A2 be fine with either middy or carbine gas...with no reservation?
well i dont remember pressure specifics for middies, but carbines with 16" barrels are a lot higher pressure than rifles- so the heavier rifle buffer doesn't hinder, it helps. i would imagine that a mid-length 16" is comparable pressure to rifle, as the hang time is about the same.
the farther the muzzle is from the gas port, the higher the pressure build up. middy's extend the gas port out closer to the muzzle, to more closely resemble a rifle-legnth system- which the platform was originally designed for.
deja vu? i think this exact same topic s going on in a different thread right now
Thread trajectories sometimes go sideways, at which time they can deviate so far they're unrecognizable...
In any case, I'm up to speed on the specs for pressure and chamber-port-muzzle distance relationship, however I've read you can run TOO HEAVY of a buffer. Thus, it's not recommended to run an H3 or 9mm unless the use dictates it (?) However, the rifle buffer is much heavier than any of the carbine ones, so I'm specifically curious as to why you hear unanimously positive responses about using it.
Does it have something to do with the longer distance travelled by the buffer?
Thank you!
