Hesitant to submit a review with this little time behind the upper, guaranteed to forget to later. Fit and finish is great. Everything squared away and lined up nicely. Turnaround time from order submission to doorstep was real quick. Business as usual on the Bravo Company side of things.
To the point:
Slapped it on a lower with a decent trigger and had time to get out and get this thing on-target and hot. Zeroed with 77gr OTM. Zero ammo was CBC, also had some Black Hills through it by the end of the day. Working with a 3-9x and lacking 5.56 precision experience, put together more than a few MOA and sub-MOA 5 shot groups. 10 round groups set some personal records as well at 100-500 yds. Not ample time, but enough to conclude the upper is capable of more than I am.
If you're in the market for a mod 1, you could do much, much worse and arguably no better for the cost of entry. Continually impressed by the product and work ethic of the folks in Wisconsin.
Holy @$% this is the best manufactured, highest quality components ever combined to make a super mk-12, forget about the rest, BCM is the best, hands down!!!!
I've had this upper almost a year now. I've run Privi partizan 69gr and 75 HPBT through it which both averaged 1/2 Moa. With Southwest ammunition's Run N Gun 77gr SMK's i've got one 3 shot group right below 1/2 Moa and then another that i shot which is the best three shot group i've ever shot in my life at 3/10ths of an inch. I know 3 shot groups are frowned upon but thats more or less a shooter test. Fact is this rifle will group. BCM makes a quality SS410 barrel, i couldn't be happier.
