    Mine finally arrived. 1.1 oz. less than a standard M4 upper with FA. Leaving off the dustcover and associated parts would save another 0.7 oz.

    Haven't received mine yet. Is the 1.1 oz weight savings based on the weight of stripped LB/no fwd assist provision upper vs. that of a complete M4 upper?

    Just curious since I weighted a stripped Daniel Defense upper and it was only 202 g or 7.1 oz.

    Edit: Rob_s, thanks for the PM.

    Micor Titanium FH

    I wasn't sure if I should post in the parts chart thread or this one, but since it meets the featherweight criterion, I'll place it here.

    This arrived today and will be going on my Robb-inspired lightweight. Micor Industries titanium flash suppressor, optimized for 1:7 twist barrels. I believe 1:8 through 1:10 are available.



    It's actually 37.5 grams or a tick under 1 1/4 oz I haven't installed or tested it yet.

    from post 107 in this thread, when I weighed the Cav Arms lower (LPK installed):
    Cav-15 MkII Lower + CAR Buffer/Spring: 1lb 11.6oz

    So maybe an ounce or so lighter since you cut the stock.

    Are you putting it on a 14.5" or a 16"? I'm wondering if these will be long enough for a 14.5 perm attachment. Crush washer with silver solder seems like it would be very close..

    I plan on using this on a 16".

    The Micor suppressor is exactly 2" long and will add 1.5" to the overall length, so you'll be right at 16" with it.
