The set fits together very tight. I ordered all the parts to build a 6mm ARC.It shoots .6 with Hornady match and .4 inches at 100 yards with the precision hunter ammo. If you want to build a precision AR this set works great.
It's a step up from mil-spec looks great and I'll be ordering my receivers from Combat Armory
