re: CZ 557 Synthetic Rifle Weight

Man, I feel your pain. It's frustrating to look forward to getting a new gun only to find out it's not what you thought it was. CZ also probably doctored the weight of the gun some. A similar CZ in 6.5 Creedmore w/ a 20.5" barrel weighs 7# 14 oz. The article read about the CZ admitted the synthetic stock was heavier than usual. Although don't have a CZ, I've previously gone down the gun weight "rabbit hole" before. Many years ago when I was deer hunting w/ a Winchester M70 in 270 Win, I decided I wanted to make it into a "mountain rifle." I changed scope rings, changed to a 2 piece scope base, drilled holes in the metal side of the magazine box, replaced the wood stock w/ a light, synthetic stock and changed the scope from a full size 3-9X Leupold to a "compact" 2-7X Leupold. I probably saved a few ounces. There are a few things you can do to shave a few ounces, depending on how much work and money you want to spend. Nevertheless, it's still going to be heavier than most guns.
-Change scopes (Leupold 1-4X 9 oz; Leupold 2-7X 11 oz). It looks like compact scopes have been discontinued, but if you could find one that's straigh 4X or 2-7X scope, you'd save a few more ounces.
-Bob and recrown the barrel (reduce the weight >1 oz/inch, depending on how thick the barrel is). This will probably also change how the gun handles, maybe and improvement, but maybe not.
-Change scope rings as already mentioned.
-I don't know how heavy the stock is and just how much weight you could save w/ a different synthetic stock. You can weigh the CZ stock and compare it to others.

How does the gun shoot?? Share some pics w/ us.
