I'll add my .02 in to the thread, even though the OP is already committed.
I use a SCAR17 as a match rifle in NRA High Power.
Sitting rapid fire @ 200 yards on SR target with Hornady factory ammo. 60 seconds, unloaded rifle. Load, shoot 5, reload, shoot 5. This was done with no spotting scope, using the factory iron sights,
without a shooting coat. Only add-on was a Turner sling. (I can clean the target with this rifle with rapid fire, routinely, with my Creedmoor coat on)
So accuracy ... yeah. It has that. No, it won't keep pace with a true match rifle shooting more refined handloads (because that's an X ring game), but it'll definitely keep me in the 10 ring consistently.
As it is currently equipped for High Power across the course matches;
EDIT: Bah. this isn't how it is currently equipped - I swapped that muzzle break for a Smith Vortex to be NRA legal.
Note that I have changed out the folding stock and added a VLTOR. The folding stock.. well, it really, really sucks for positional shooting; especially if the user has a beard. (Ouch).
I also have a Leupold VX IV long range scope on quick throw heavy ARMS rings for precision shot placement on pesky squirrels.
SQUIRREL!
I have shot it in all sorts of conditions ranging from 100+F summer days to -20F winter days.
This is the same rifle dressed with the folding stock, Harris ultralight bipod, and that Leupold scope.
I shot that rifle extensively through 2014 in high power matches and didn't need to clean it. It stays IMMACULATE. Even when shooting dirty Malaysian surplus ammo. Or even dirtier Winchester ammo.
It's a great rifle, but the entry price is steep.
Is it worth it?
That's up to the individual to decide.. but for me? A lot of other rifles are collecting dust since I bought it. It is a fantastic rifle... except for that pesky folding stock thing.
