LMT E-carrier and buffer weight

[markm]

Good Grief! If you did a simple BCG swap and the problems went away, I'd get rid of that fukking gimmick BCG.

I have to think there's something else wrong here.

***UPDATE***

Swapped out the H2 buffer for an H like I planned to and ran 40rds of MK318 through it. Fired it 5rds at a time so I could check lockback.

All 40 fired and cycled with no problems (had been failing to cycle about 1/2 the time with that ammo and an H2 buffer).

First 5rd mag locked back. Mag #2 and #3 failed to lock back but otherwise functioned fine. Mags 4-8 locked back just fine.

The reason I use MK318 as my "litmus" test is that it is the first 1K rounds of SHTF ammo I have bagged and ready to grab. MK318 is not the only "premium" fodder that I have (by any stretch) but all my AR's zeroed thus far have been accomplished with that load. Can't get it anymore either.
