AR Parts and Weights

[frsteve]

Hi There,

This is only my 2nd post (please show mercy) ... I know there is a google doc that others have posted, but I found that a lot of that information is dated or inaccurate.

Here’s the stuff I measured myself and using this scale:

(I'll update post with the scale - when I'm allowed to embed URLs) - on amazon, you can search for "

EatSmart Precision Pro - Multifunction Digital Kitchen Scale w/ Extra Large LCD and 11 Lb. Capacity"

For items that were less than 5 ounces, I stuck a 5oz scale weight on it and took the difference. Some scales aren’t as accurate from 0 to 1oz and I wanted to eliminate that inaccuracy in my measurements.

I doubt any of the rifles dedicated for this sport are using BUIS or Bullet Buttons.

The OP was weighing what he had and posting it. Some of the stuff may be more relevant than other items to different people. Thanks for the info.
