True that but some people like me like having 1 lower with multiple uppers hence the heaver BCG is better cause I don't have to fart around with that stupid spring/detent buffer tube when I switch my set-up.Edited to agree. (and cause no one sells the old Colt 'half-moon' carriers anymore).
We expect Armorers to match the buffer to the ammo in use.
For example, I always run the H2 with Mk262, etc. With lighter 223, I'll usually use a carbine or H buffer, whichever is more comfortable. A H2 buffer is too heavy to reliably cycle light 223 ammo on a shorty, particularly a new one with a freshly sized gas port (they get bigger as the thousands of rounds pile on). I would challenge anyone to notice the difference in firing a enhanced SA vs a FA carrier, (grams) whereas changing the buffer (ounces) provides a noticeable difference in pulse and action speed that anyone could notice.
Thanks dangertree for the clarification.![]()
FWIW: We sell both.

Milling the sear trip portion of the carrier does not reduce its functional strength. It rides straight back and forth. The trip area of a FA carrier does not increase its functional strength.
The difference in weight between an enhanced, current SA Carrier vs a current FA carrier is measured in grams, whereas the differences in weight between buffers, which move in tandem with the carrier, is in ounces. If someone wants to change the weight of the moving mass of BCG and Buffer, the buffer is the place to look.
It makes no difference to function, performance or bolt life. Sounds cooler to say maybe?
I can never understand how people willingly pay more for a FA BCG because it is FA. If anything, the SA carrier takes another couple seconds to manufacture. I know people who have purchased inferior brands of bolts (when I say inferior, I mean their bolts and bolt hardware break quicker than some other brands), because it came with a FA carrier. Boggles the mind. The carrier is not what breaks. Buy a good unit from a known manufacturer.
Then there are other companies selling lightened carriers, and other people extolling the virtues there.
If someones rifle isn't cycling properly, the difference in weight between a FA and a SA carrier, won't be the cure.
FWIW: We sell both.
mine came with an enhanced ar15 carrier, not a FA
enhanced as in weight between SA and FA.
might not be the appropriate term, but it's the only one I have heard
From left to right:
SA, enhanced, FA

Dave,
Are your NEA-15's supplied with a true FA BCG or an SA "Enhanced" version with the milling cut? I'm not clear what Enhanced means here whether it applies to finish or mill cuts.
What is the purpose of the middle "Enhanced" BCG?
Will your company be offering a dry lube coated version in the furture? Or perhaps a hard chromed version?True FA
