Hoping to start a list with common part weights.

AR/M4 AR General Discussion
1

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.

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
