I am a 100% permanent and totally disabled veteran. I recently got back into shooting, and my first rifle since leaving the service nearly 20 years ago is your OH2500333 .300 blackout. I cannot tell you enough how impressed I am with this rifle, especially given the top tier quality delivered at a fraction of the cost of more expensive and less reliable manufacturers. I feel like I cheated. For less than the cost of a diamondback or PSA, I got a something that rivals or surpasses a Saint Victor. I have full confidence in this rifle. I’m stoked I have one of the originals, and I’m looking forward to your 6mm ARC when I finally have the money for it. I had a feeling in my gut about this company, and seeing that it started with a fellow veteran sealed the deal for me. My instincts served me well, as there is not one single flaw with this rifle. Not. One. Well done.
