Guys sorry for the delay in posting this but I'm very happy with the Hardened Arms 300 BLK upper, I'm shooting sub MOA out to 100 yards with my 1st 130 Hornady spire reloads, it cycles great & for the money its hard to beat. Its going to be my go to deer/hog gun this season.
Had my 9 & 6 year old out shooting it yesterday & they loved it, low recoil & they were both drilling the paper at 100 yards, time to get them in front of some animals :-)
Its not Mega or Noveske but if you want to get into 300 BLK on the cheap like I did I'd recommend it. One thing I will replace soon is the hand rail, I like a 15 inch rail but other than that I added a Vickers Combat sling & really like this gun & round. I used a Black Forge lower that I got from a LGS for $69 bucks, so the total is a very affortable set up.
