Duramag 20 Round 350 Legend Magazine for AR-15 - Stainless Steel - AT3 Tactical

Duramag 20 Round 350 Legend Magazine for AR-15 – Stainless Steel


BA 16 Inch .350 Legend Hanson Profile Carbine Barrel

This barrel combines the ergonomics of a short 16-inch barrel with a big bore caliber like .350 Legend. A carbine gas system with an included pinned gas block, 16 ” barrel length, and Ballistic Advantage Hanson profile ensure reliable function and smooth soft recoil. Precision machined from 4150 Chrome Moly Vanadium Steel and finished with QPQ Corrosion Resistant Finish.

One of the best features of the 350 Legend is that it doesn’t require too many special components.  You use a standard 5.56 bolt carrier group, a .750″ gas block, and a Carbine gas tube.  For better reliability with the straight-walled 350 Legend cartridge, make sure to use a magazine specific to the caliber.

.350 Legend

The .350 Legend is a top choice for hunting large game and making big holes in targets. The .350 Legend is perfect for states that legally require straight-walled cartridges for hunting. Not to mention the only parts of an AR15 that need to be changed for .350 legend are the barrel and magazine.

IMPORTANT: A standard 5.56 1/2×28 flash hider will not have enough clearance for a .350 round to pass.
Use a 9mm 1/2×28 muzzle device or one designed for .350 Legend rounds.
Before installing a muzzle device, ensure a .350 Legend round will drop freely through the muzzle device bore.
