UPDATE: Flawless 1st Outing

by -

Spent last night mounting and leveling the scope. Got to the indoor range today. 3 shots at 25 yards. Only 1 on paper. Bore sighting showed I was way off. Got the scope dialed in. Next 3 shots, tight & right. Couple clicks later and I was center punching bullseyes in 1 inch groups consistently. Virtually nonexistent recoil. My buddy is jealous. His 5.56 AR punches back. Mine doesn't. He wanted to keep it.
<br>That was just 60 rounds to break things in. I'm really not sure how it could perform any better. This will be a keeper as long as it's durable.
<br>Shooting outdoors at 100 yards tomorrow. We'll see how that outing goes. Confidence is high so far.

Unbelievable AR for the price!!


Lots of bells and whistles for a budget AR. Everything well made and solid except for the mag it came with but who cares about a crap mag! Light weight, no polymers, 15" rail w/full picatinny, B5 furniture, mid length gas system and good materials for everything! Shoots like a 22!!!! SOLID RIFLE. Now all I need is that Holosun 503G and Primary Arms x6 Magnifier and I'm all set for anything! Did I mention this rifle is really fun to shoot?!
