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

this needs to be stickied and have more data compiled, ive searched hell and high water for component weights especially an assembled lower.

Weights of uppers and stocks can be found in these links:

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
