    Best products

    BCM is my go to manufacturer. This build would also have a BCM barrel/BCG if you guys made a 6.5 grendel.

    Works

    I don't have the tools or the knowledge to tell you how "milspec" this is and since I have a duty rifle already and this is for another safe queen, I can't tell you whether I can trust my life to it BUT it will be awesome for showing my "kit" on the old Instagram and putting in a neato quote about "doing work". The BCM items I run in patrol always work and fit as advertised though so I have no reason to question this.

    Bummed I had to return it.

    Was great but had to return it in exchange for items I didn't already have. It was a gift but I already had one.

    Upper Review

    I wanted a UCWRG upper to match the lower I managed to snag before they went out of business but this upper is top notch quality.

    BCM M4 Upper Receiver Assembly

    I have been building and using professional grade AR-15s for over a decade. This is the upper receiver assembly I recommend and use exclusively.
