Yeah, I grabbed a couple to try on newer builds down the road. Not going to switch out my existing BCM blem uppers for them. But I'll give them a try going forward.

Haven't heard of uppers breaking, didn't know there was a need for a stronger one. I like the extra space with the fa being moved up.

I've got a 20" 5.56 precision-type setup for long-range plinking. I'm thinking the increased rigidity of the upper, to lock in the scope mounting-rail better with the barrel snout can only help with shot-to-shot consistency. Probably a waste on a CQB 14.5" setup unless you're using the barrel as a pry bar to open steel doors. and it's half the price of the Noveske Gen III upper.

It's a nice addition to the market. Not sure it will sell well without them integrating it into their rifle and upper sales. Unfortunately BCM is stubborn and still clings to Keymod of all things.

If it seriously cut down gas to the face, I would try one. If not, it's useless IMO.

Doesn't seem like marketing has done a good job with this piece.
- Most of the early work with this design seems to have been focused around reducing bolt breakage. - Read a fluffpiece today in a gunrag talk about how it reduced deflection from uneven bipod loading by some ridiculous amount. - Larry Vickers who is now skinny again seems to have zeroed in on the idea of it protecting your face from OOB - Finally, BCM's copy looks like they can't express what actual advantages it has. It is "just $20 more" (than an overpriced $100 BCM upper), but I'd be in $60 on an assembled Poverty Pony anyway. $120 is play money in AR land. I'm the sort of person that shims and glues barrels into uppers, so I'll give it a shot with miniscule accuracy improvement and theoretically improved bolt life in mind. Quote HistoryQuoted:

I suppose this is why we're all running around with 20" barrels, birdcage FHs, and carry handles. I don't understand this MK2 upper anyway, not for me. |

I'm planning to buy a 14.5" MK2 BFH-ELW upper with an MCMR-13 handguard from BCM's store as a Christmas present to myself; I already have one of their lowers on order. This will be my first BCM rifle; will post my impressions of the URG (and the MK2 specifically) once I get it.

Perhaps it’s another option in the category of Vltor MURs and Aero M4E1 threaded uppers. Slight benefits to be seen with precision minded builds. Quoted:

So, they beefed up the amount of material at the barrel nut and shrunk the forward assist. I don't see how either of these things are not benefits.
As I posted in the other thread.

As I said in the other locked thread:
I'll be buying one early 2020 when my bonus comes in, unless I hear something disqualifying. Idk if the improvements mean anything, but I was going to buy a BCM upper anyway so for $20 more, might as well try it out and have something a little unique. If the claim that it helps with gas in the face while shooting suppressed has any credence it'll be worth it. |

To my astonishment, my MK2 BFH-MCMR upper was delivered earlier today (estimated delivery date/time was Monday afternoon). I slapped the upper onto my new BCM lower (which arrived yesterday) and then added my EOTech EXPS3. As someone whose other AR is a Daniel Defense M4A1 (fitted with a RIS II), the weight difference is a shock to me - this rifle feels almost like a toy compared to my DD. Overall, though the MK2 upper is pretty much what I expected - kinda novel, not in an especially useful way, but nice to have if you happen to be in the market for a BCM upper.
I'll post pics once my BUIS and Magpul ladder rail covers (for the 12:00 Picatinny rail) arrive, which should be in the next couple days. I probably won't run it with a light, at least not just yet. |

I doubt they are forging their own receivers, not even Colt has that capability. And even if they did buy their own machinery and had the facilities to house that machinery; forging components is not something you just decide to do, pay to play and immediately pump out quality components. Finish machining? Maybe..possibly, but why would they pay Vltor to manufacture charging handles if they had the machinery and skilled operators to machine receivers? BCM isnt known for actual manufacturing..theyre known for sourcing parts, assembling and qc. |

I'm not one to really give a shit as to gimmicks and such but I have owned some MURS and this is in that category but doesn't limit your handguard selection as the Vltor's can. I bought one to mount up a Larue Stealth 20"er and as with all BCM Uppers had to heat it to seat it. I do love the tightness of the barrel lock up on BCM uppers as I do the upper to lower fit on a RRA lower. It's a nice Upper

Yeah, Ive seen that picture before. I dont know what to make of it because the the forging press is only one part of the equation. There is much more equipment necessary to the process as a whole; from automation (to run with any efficiency) to preparation of raw materials (cutting), to heating furnaces, to the forging press itself, dies costing likely in the high tens to hundreds of thousands of dollars (which wear and must be replaced periodically), flash trimming, blasting/polishing machinery etc. and the skilled (experienced) personnel (consultants, engineers, metallurgists, experienced operators) to setup and run the equipment. Thats a huge investment in just forging and not including finish machining and the associated costs of equipment and skilled labor (which hopefully you can find, and recruit in your AO). It doesnt make much sense unless you are planning to oem forgings for other manufacturers and/or forge parts for more than just AR15's.

FYI, the DD RIS M4A1 handguard will work with the MK2 upper, but not without a *little* bit of filing on the anti-rotation tabs. Also, due to the thicker reinforced upper, the hardware (mounting bolts) install procedure is different than normal, and can only be done one way. |
