Excellent kit!!
I have purchased many "complete uppers" from another VERY well known the letter supplier and thought they were exceptional, until I bought this one! Who ever assembled this did it right. Everything came "wet", pre-lubricated. I swapped the muzzle break for a linear compensator to find that the proper grease had been applied. These little details are missing from the "other" supplier. This shows attention to detail, and is worth the couple of bucks for peace of mind knowing it was done right. This supplier made made my "go to" list for sure.
USLove it
I bought the 7.5" 5.56 kit not too long ago, after building and having some time with it, I was highly impressed with it especially for the price it was at. I knew I had to buy this 300 BO to go with it. Everything is well within spec between both kits. I would suggest a kaw valley trigger spring set to go with it, will feel like a drop in trigger! I should have bought 1 more of each before price increase but still definitely worth every dollar I spent!
Pretty solid build
I’m over all pleased with the build. I’ve had a good bit of fun with it. The only bad things I have to say is the selector switch won’t completely go level on safe (but the safety is still engaged) and I’ve taken it apart twice to see if something is in the way but it just seems to be a fault in the selector. And the kak brace tube had some nicks on the threads so it didn’t want to completely tighten down. And the reciever end plate seems to be slightly bent because it won’t lay flush with the end of the reciever.
