SAA 16" 5.56 NATO M4 1:8 Match 416R Brushed Stainless Steel Finish AR-15 Barrel
This SAA barrel is 416R Stainless Steel (SS) M4 profile (M4), Match chamber with 1:7 twist rate Polygonal rifling, Carbine-length gas system and standard 5.56 1/2x28 threads. As with all of our AR15 barrels, this barrel will work with any and every mil-spec upper receiver, forged or billet.
SS barrels have the advantage over military chrome-lined barrels since chrome lining diminishes the barrel's potential accuracy while SS barrels have clean rifling and chambers (verses lined barrels). SS has the advantage over chromoly barrels as SS is easier to clean as well as being corrosion resistant. Polygonal rifling has many advantages over classic lands & grooves rifling. Polygonal is easier to clean (L&G rifling has 90 degree angles verses the obtuse angles of polygonal rifling), longer barrel life (less friction) and greater potential accuracy (a better gas seal with the fired projectile).

Came well packed, looks good out of the box. There was a gas block dimple that made it easy to align. Got the BCG combo sent in. Will buy again.
