If that's not true then I for sure go with aluminum and not even gamble with the poly

Don't think just a polymer lower will shave a pound.

I think a lower and upper that's polymer might come close.

A polymer lower would be perfect for a dedicated 22lr, or a range/light use rifle for the wife. She's 5'2" 110 lbs, and has a hard time holding my Spike's lw and RUC (both under 7#) steady shooting offhand. I think in conjuction with a heavier stock for balance and a brake she should be good to go.

Yeah both a polymer lower and upper could do it. A Carbon 15 M4gery comes in around 5.5 pounds, while my LW build with standard receivers is 6.5.

Shave a pound?! Only if it's made of AIR! A stripped forged lower receiver only weighs in the neighborhood of 8.7 ounces. http://megamachineshop.com/armscatalog/007FORGEDLOWER-M0200/loader.html How the heck can you save a pound in a part that doesn't even weigh a pound? Cmon guys. Even if you factor in a polymer LPK you still can't do it. It just doesn't add up.


ETA: Forged stripped upper only weighs 6.9 ounces. http://megamachineshop.com/armscatalog/003FORGEDUPPER-M0016/loader.html. for a grand total of 15.6 ounces.

Mathamaticaly it just cant be done.
