Agreed ATRS would probably be my first choice but I really like my XCR.
I have had for 5 years, well over 10,000 rounds and no issues.
It took some doing but with the heavy barrel I was able to work up a load that is right around MOA consistently. With that same load the light barrel is around 2 MOA which is all I need it to be. I was never able to find any factory ammo it shoots decent tho.
I was not a fan of the fast stock but the Dlask AR stock adapter works well and you can use any AR stock you like.
Keymod version with the light barrel actually handles pretty nice.
The heavy barrel is pretty heavy. I think it's about 1.6 lb more than the light...
