    Hoping to start a list with common part weights.

    Just got a scale in the mail, measuring some of my weapon parts, and I've read a few topics where people are putting together weights of different items. I'm hoping here that others will post weights to make this a longer list for others to share and distribute.

    Just doing AR15 parts, for simplicity.

    I'll start it off:

    Lower parts:
    A2 stock with trapdoor and rifle length extension (no buffer or spring): 1 lb 4.30 oz
    Rifle length buffer and spring: 7.25 oz

    Upper parts:
    BCM full auto BCG: 11.55 oz
    BCM charging handle: 1.15 oz

    Optics, sights and sight mounts:
    TR24G in LT-104 mount: 1lb 4.80 oz
    KAS M203 leaf sight: 3.60 oz
    Troy folding rear sight: 1.75 oz

    Lights and light mounts:
    VTAC flashlight mount: 1.55 oz
    Surefire 6P Incandescent: 5.35 oz
    Surefire G2 Incandescent: 4.1 oz
    Surefire G2 LED: 4.4 oz


    Magazines:
    USGI AR-15 mag with green follower: 4.00 oz
    Magpul PMAG (non-windowed): 4.80 oz

    I started a thread like this many moons ago.

    Anyone remember the Maryland AR Owners MSN group? it doesn't appear to exist anymore but it had a huge spreadsheet on it of weights of pretty much everything you could think of at the time.

    another useful piece would be an assembled LPK with a buffer tube, spring, carbine buffer minus the stock. Using USMC03 link you can add the weight of the stock of your choice to get a complete number. Also an assembled lower weight without a buffer tube installed.

    Any idea how much an A2 birdcage FH weighs. I want to try a AAC Blackout (non suppressor threaded) which is 2.9oz according to AAC, but I have to keep track of weight for my lightweight build
