Re: UBR Stock and Weight.
If you want lighter, then I agree that moving to another simpler stock like those suggested above is a pretty simple solution. The ctr being very popular and the b5 bravo stock also growing in good reviews.
That all being said only you can determine what is most comfortable and manageable to you. My rifles have longer rails on them and as such I'm actually looking to move to the ubr from the ctr to better balance the front heavy uppers I run.
You should try to get together with your buddies again and try slapping your upper in one of their lowers to compare the feel of the different stocks they have.
That way you can try before dropping the cash for a new stock & re.
