Re: Rock M24/M40 barrel weight
I have never weighed them, but I have two rifles in M40A1 stocks, with Rock M24 contour barrels (one sports a TAC30). While niether are 22", I can say with 24" and 25" tubes, they balance pretty well, IMHO; however, they are not lightweights by any means.
If you speak of a 24" Rem. varmint countour, I would think that a 22" M24 contour barrel would be significantly heavier.
