I just bought a used LMT lower that came with an H buffer. I also just purchased an LMT upper with a Noveske Afghan middie 14.5" barrel. Should I replace the H buffer with a standard right away, or should I try it out first and see if there are any problems at all? Also, are the spring rates different between the two as well, or are they the same?

My Defender 2000 M4 came with a H buffer I replaced it with the 9mm buffer I could tell a BIG Difference ( FASTER FOLLOW UPS ) standard & H buffer I cant tell any difference My back up Home Build Bushmaster lower/VLTOR LMT M4 14.5 upper I run the H buffer in it just because Im to cheap to buy another 25$ 9mm buffer BTW My M4`s run on any buffer as should yours I shoot 223rem and 5.56mm ammo from 45gr to 77gr OTM No trouble with the extra Heavy 9 buffer I have under 3000rds fired so far |
| Yeah stick with the H buffer I'm not sure what the above poster was talking about but H buffers are the common remedy to sove feed issues. The heavier buffer weight lengthens the time that the bolt takes to cycle there by promoting better extraction and feed. However, I guess I could see a problem if the something was wrong with the spring. |

but H buffers are the common remedy to solve carbine feed issues. Fixed it for ya.  H buffers are for slowing down the cycling on over gassed carbine length gas systems. Middies aren't over gassed by a too short gas system, so H buffers are unnecessary. However, having said that, just run the H. If it works, fine, if you have problems swap it out. No sense spending money to fix something that aint broke.
