    Great performance for the price

    Accuracy is fine, consistently prints 2 MOA groups with ball ammo. Where it really shines though is how soft it shoots. Paired it with a BCM MK2 (Vltor A5) buffer system and despite being short and suppressed it's one of the softest-shooting ARs I own. I've only had it for about a month so maybe talking about reliability is premature, but I've put ~1000 rounds on it, no cleaning, and she's been flawless.
