This is my brand new, Noveske Gen I RECCE Light 300BLK AR with a 16 inch barrel. I am using a mix of Remington 120 grain 300 AAC Blackout, and Black Hills 125 300 Whisper. This was the very first time i have ever used this brand new rifle. Out of the 60 rounds i put through it, i only had 3 issues with cycling the next round which happened in the second magazine. The second magazine was as i showed a mix of the two rounds i used, and the first magazine was all black hills. I found that the Remington rounds had more issues, than the Black Hills. I did not Lubricate the rifle at all before i used it. Everything is stock and as is when it first comes out of the box. NOTE. At the end I shot an Empty Propane Tank that "exploded" after the bullet hit it.
2ndNOTE : Fixed my problems awhile back, and i will have new videos soon. I just needed a new Buffer and Buffer spring, because stock mill spec magpul equipment is not THE GREATEST. Lol
