I have one of the early GSRs that was spec'd with a 16.5" barrel, back when all those barrel lengths were actually made at 17.25" long (w/o the flash hider).
It's a good all purpose rifle with iron sights, detachable magazine, adjustable stock length, and optic mounting options for traditional scopes or forward mounted scopes. It comes with a humongous 10-round metal magazine, but shorter polymer 10-round magazines are available as well as 3 and 5 round magazines.
The bolt is a bit sloppy when open, but that's mostly because the rear receiver ring is so brief in length. Other rifles with more receiver around the bolt aft of the magazine support the bolt much better.
The trigger is good, but could use a lighter spring. Years ago I swapped the factory Ruger spring with a lighter one found in my pile of extra springs. That alone made a huge improvement and I didn't have to do anything else to the trigger, like I've had to on other guns.
If making "scout" weight is your thing, get the polymer stocked version and put a 3 or 5 round poly magazine in it. If not, get the laminate version as it weighs about the same as most wood stocked hunting rifles. Normal weight rifles keep felt recoil down without needing a muzzle brake, as compared to some polymer stocked rifles. Of course, the GSR has a rubber butt pad to help even further.

If anyone cares, my GSR (with carry strap) weighs as little as 7 lbs. 2 oz. as shown in the top photo if you remove the magazine.
Adding things porks the gun up. The middle configuration is at 8 lbs. 7 oz. while the bottom configuration is at 8 lbs. 13 oz. Both weights include a fully loaded 5-round metal magazine.
