SAA Match 416R 5.56 NATO 16" Stainless Steel 1:7 HBAR AR-15 Barrel
This SAA barrel is 416R Stainless Steel (SS) Heavy Barrel profile (HBAR), 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 milspec 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). The 1:7 fast twist rate will stabilize projectiles up to about 90 grains (although most of the better, match grade projectiles top out at 77 grains). And it will handle as light/short projectiles as low as 52 grains, just fine as well.
And yes Maryland, this is your barrel (HBAR).
