I did some measurements of my own and this is what I have so far:

Stock B2K4 Barrel: 134.7g (4.751 oz)
Stock B2K4 Pull-Pin: 11.2g (0.395 oz)
Stock B2K4 Bolt: 25.8g (0.910 oz)
Stock B2K4 LPR Assembly: 37.8g (1.333 oz)
Stock B2K4 Ram Assembly: 71.5g (2.522 oz)

*Note about methodology*:
My scale was zeroed before each measurement. A series of 10 measurements were taken for each part listed. The totals added up and the mean weight used as datum. Erroneous or anomalous readings were discarded. Weights were taken in Grams (g) and then converted to Ounces (oz).

I'm looking to make some measurements myself before and after my mods. Could you recommend a digital scale thats reasonable (price & accuracy) for me to buy?

[Eric the Great]

there a ton on ebay for ~$15-20 shipped. they probably wont be as accurate as a namebrand scale, but this isnt rocket science.
