I was very pleased with the product itself and the very speedy shipping and careful packaging, needless to say it spoke for itself after the build because of now two of my co-workers have ordered from Blake King and they are getting me to build a pistol for them as well.

Looks great, great quality. Only put 100 rounds through it so far, but have faith it’s going to be a great upper.

I was a little apprehensive at first as I had never heard of B.K firearms but I immediately liked there website as it was simple with accurate in stock numbers that are updated constantly.
I first ordered the 10.5” fssr parallax and was so impressed that I then ordered the same but in 7.5”.
Very impressed with build quality and function.
I haven’t fired the 7.5” yet but a friend purchased the exact same product and based on a conversation with Blake(the owner) who advised using an H2 buffer and spring, there were no jams, miss feeds or cycling issues and all casings were ejected at the 4 o’clock position…perfect!
Keep up the good work Blake and team, fantastic job and fantastic product.
I highly recommend these products!

I was looking for a 7.5″‘ upper to compete a backpack project. The hybrid 1913-MLOK hand guard was perfect for attaching accessories and still keeping it slim enough to insert and remove from a pack without issue. Now I am looking forward to doing another one in 300 blackout.
