Looking for user feedback of White oak armament barrels. I'm looking at using either their SDM 20" barrel or their 18" barrel in my long range ar build. Those of you who have them, would you recomment them to someone else? I am also looking at compass lake engineering if reviews of the WOA come back negative. Depending on which barrel I decided to use, will dictate whether I go with an SPR type rifle or a SAM-R rifle. Any feedback is appreciated on either of those rifle types for shooting out to 600 yards.
Thanks
Thanks
