You are saving a pound going to the A2 chassis. Pull the monopod from your A1 for more weight removal.No kidding. I want to sell my A1 but the A2 release really hurt the A1 owners resale value! My A1 fully loaded with Gen 2 Razor, NO suppressor, (419 brake), slim 7saum barrel and covert handguard is still around 18#. I hiked with it through Colorado for nearly 40 miles over 7 days. Not an easy task but it can be done with a good pack. I am looking for lighter alternatives. I suppose a Carbon Fiber barrel and lighter scope could shave 5# or so off.
