Advice on 6.5 Grendel Satern 24" bbl 5/8 x 24 thdd end protector for best accuracy

[CCW]

The Satern store had everything I wanted in a barrel but the 5/8 x 24 threaded end. I really wanted a 11 degree dished target crown. These Satern barrel riflings terminate in a sharp square end, that asks for mutilation. How about a Krink Style thread protector, basically a hollow tube internally threaded 5/8 x 24 on one end?

God bless,
