After looking for more than a year I ordered a BCM MK12 upper Bravo Company last Wednesday afternoon and had it Monday morning.
This is a BCM Mk 12 Mod 3X-Bravo (DD14) with BCM auto BCG, BCM sights, standard charging handle, A2 flash hider.
* Daniel Defense 14" LITE Rail
* BCM SS410™ 18" Stainless Barrel, Ionbond Black DLC
* Rifle Length Gas System
* Pined Gas Block
* BCM Bolt Carrier Group (HPT/MPI), auto
* Standard BCM Charging Handle
* M4 Feed Ramp Barrel Extension
* M4 Feed Ramp Flat Top Receiver
* T-Marked Upper Receivers
* 1/8 Twist Rates
* 5.56 NATO Chamber
* 410 Stainless Steel
* HPT (High Pressure Test) Barrels
* MPI (Magnetic Particle Inspected) Barrels
I mounted this on my LMT match 2 stage lower, with Magpul UBR stock and MOE grip.
Here is the BCM MK12 SPR with the Leupold MK4 4.5-14x50mm from my bolt action until I pluck up the courage to get a new Leupold MK4 3.5-10x40mm
BCM Mk 12 SPR 18" barrel with 14" Daniel Defense Lite rail
When I received this upper I went over it with a fine tooth comb, this was absolutely perfect not a finish mark or scratch at all. Even the BCM/Troy sights screw heads were perfect. I have never seen an upper this cosmetically clean. The gas block was perfectly centered inside the DD Lite rail and the flash hider is timed perfectly. Great job guys!
Well it sure looks good, but how does it shoot? After shooting it on Sunday to get it on paper at 50 yards I took some time out today for some recoil therapy and took the BCM SPR back to the yard range to attempt some 100 yard groups. I have to say I really don't know what the USMC SAM-R Chamber is but it ****in' works!
It was a really windy day here in Colorado and the wind was so bad while it was moving my target stand around, it was also actually moving me! However, I would try to time my shots in the lulls in the wind I managed to shoot six good 5 shot groups, three of which were true sub MOA groups I was using Black Hills red box 77gr SMK load and Fiocchi's Exacta 77gr SMK. The other three groups I would manage to time the wind and get 3 or 4 rounds touching and then the wind would pick up and I would have 1 or 2 fliers.
I will try again when the wind lets up a little and move out to 200yards to get a good handle on performance with loads from 45-77grs. So far I have shot 50, 55 and 77 grain loads all with excellent results.
I am very, very happy with the BCM upper. Truly excellent fit and finish in the build, and a fantastic barrel!!
I have bought LMT uppers, Daniel Defense rails, and BCGs and a ton of small parts from BCM before but this was the first complete upper and I am extremely pleased, and it wont be my last!
Thanks guys I really enjoy investing my money with a company that so obviously takes such pride in their products and reputation.
