An honest video of zeroing an AR-15 Pistol chambered in 300BLK. 7 inch match grade melonited barrel, 1/8 twist, free float handguard, vortex magnifier. Magpul K2+ grip and Shockwave Brace. Amazon bipod.

Firing Sig Sauer 125 grain match-grade ammunition out of Gen 2 PMAGs.

Zeroing at 50 yards to try something new.

Also, exploding a 2.5 gallon DEF container with 110 grain Hornady Custom ammunition at the end in slow motion. Enjoy!
