The BCM KM 13" rail weighs 7.7oz.
For a comparison, the NSR 13.5" weighs 7.9oz and the bbl nut is 3.1oz.
Pretty amazing if those BCM KM weight specs hold until final production

What's the significance of an exterior anti-rotational tab?
Sic semper tyrannis.
That's 7.7 oz for the BCM-KMR-13 rail, which is the complete weight (with all mounting items, including barrel nut).
The bare BCM-KMR-13 weighs 5.5oz and is long enough to cover the gas block of a rifle length gas tube (approximately 13").
The bare BCM-KM-10 (10" variant which will cover the gas block of a mid-length gas tube) weighs approximately 4.3oz for a total assembly weight of 6.5oz.
These are the only details we'll be releasing at this time.
Would it be too much to ask what length rails are planned? (9" specifically)
Thanks
Phreakish, edited my post at the top of the page to reflect your correction.
Forgive me for not sifting through the last 8 pages of arguments... but when is the BCM press conference to officially announce this thing?![]()
