This is a discussion on Sage stocks within the Modern M14 forums, part of the M14 M1A Forum category; Not shooting tight groups off hand but if a bunny pops out I'd have no problem snap shooting him....
The weight is an obvious downside, but the end of the world toughness makes up for it.
The only real downside is if you live in CA, Sage WILL NOT send you parts regardless, you have to find some other "Authorized dealer", and it is a PITA. Happy shooting!
Buy chassis, put an Mrad/Mildot First Focal Plane optic on it (Vortex, Bushnell Elite, Weaver Tactical, etc etc), throw on a bipod or other things you might need, develop a 175g SMK load or buy FGGM 175g, Zero rifle at 400 or 500 yards, have friend put 5 or so 6 foot by 2 foot wood targets up at random distances from 300-1100 yards, start ranging and start shooting, most fun you will ever ever have with an EBR I promise. Especially when you use the MRADS available to you for hold overs and not do the lame elevation clicks.
Oh might want to stop by walmart and grab a 1$ Chinese calculator, a thing of paper, and a pack of pens while you are at it.
I love my sage. No down sides for me other then if I want to switch stocks I have to take off the oprod guide from the barrel and reinstall a different one, so my scout is pretty much dedicated to the sage.
It's no big deal as I have several m14's but I do like to switch stock ps sometimes and the sage takes a proprietary oprod guide.
