Completely agree.

I know that the LMT E-Carrier on a new SR15 Mod2 is a different move.

I experimented with it after seeing a larger delta between PMC Bronze 55gr .223 and Frontier 62gr 5.56 NATO ammo than I wanted to see. PMC is weak AF, but otherwise good ammo. I found BCG velocity to be a little sluggish. Whereas with Frontier, it ran right but could be a little harsh.

I found the LMT E-Carrier added velocity in slow-end with the PMC and softened the stroke with the super-hot Frontier on the fast-end of BCG velocity.

I was running a BCM Mk2 T-0 (3.7pz IIRC) with Geissele Super 42 Rifle spring (their rifle spring works in the A5 system & with normal diameter buffers). Decided to try a BCM Mk2 T-1 buffer @ 4.6oz and an simply shocked at this amount of improvement in breadth of function, while still getting that comp-gun level of smoothness.
