Outstanding rifle
I bought this on sale a couple of months ago and thought it looked decent for the price. When I opened the box it was so clean and elegant in it's simplicity and functionality. I've already got a couple of crazy builds and I wanted to keep this one basic. I've only been shooting my finished build for a month but I talk this rifle up to all my buddies. It fires cheap ammo that my other rifles don't deal with as well. If the apocalypse happened tomorrow and I only had to grab one rifle it would be this one. I want 3 more.

This unit came with a used bolt that wasn't marked mpi/hpt but psa made this right in a quick and courteous manner. After breaking in the barrel and finding a compatible ammo (Winchester 64gr psp) this upper gives me 4" groups at 300 meters respectively. No malfunctions of any kind. I am very pleased with the product and service but the boar population in my area don't feel the same. Keep up the good work PSA Thanks
