What was in the box - Project AR-(20)15


The BCM upper discussed a little bit back was purchased and arrived in short order. The stats:
  • 14.5" Enhanced Lightweight Barrel (ELW)
  • Pinned BCM Gunfighter Comp Mod 1
  • KMR13 Free float handguard 
The combination shorter barrel along with BCM's proprietary ELW profile and magnesium alloy KMR rail make for a lightweight, agile and all around handy carbine. It's very slick.



Moving from a short, fat carbine length MOE handguard on my old carbine to the long and slender KMR stands out as the biggest upgrade. Modernized ergonomics / grip is hugely important, and that was one of the real driving factors behind the upgrade. Now I get to shoot like the cool kids do.

The buying experience from BCM was awesome, as expected - fast shipping, got to my door two days ahead of schedule, and the package included the customary pile o' BCM loot, too. Pretty much perfection. If you're in the market for AR gear, you won't find any who does it better.

The carbine is still obviously a work in progress. Back up iron sights (BUIS), light, sling mount and a hand stop will be added. My Aimpoint PRO feels like a pig on this thing, too - an optic change may be in order. The upper destined for another lower, too. I've got no plans to obsess over a particular weight threshold as some folks do, but I do want to retain the balance and handiness of the carbine. I'll check in as things evolve.

First range trip / break in / sighting is planned for this weekend. The folks at Lucky Gunner were kind of enough to volunteer a supply of ammo for the cause, which is very cool of them. The ammo shipped wicked fast, too - got from their door to mine in around 24 hours. So - go buy ammo, tell them T-Blog sent you, and hopefully I'll get more free ammo, which will in turn lead to more range trips for me and more gun blogging for you to read. Thus, the circle of ammo will be complete.

Stay tuned for more.

  1. Get one of the new Aimpoint Micro's, I have the previous generation and love it on my 7.5" AR.

  2. So, go with an Aimpoint Micro T-1 2moa dot, or a 4x ACOG. I really like the Magpul BUIS Pro. for iron sights.

    1. An Aimpoint T-1 and MBUS Pros are the plan now. Light will be something Surefire in a Keymod mount, handstop will likely be the BCM KAG.

  3. Will a lightweight barrel cause more stringing and open up groups during higher fire rates?

    1. From my research, fears about wild stringing after a couple may dumps are misplaced. Little to no group size change after mag dumps. The ELW profile should be especially resistant to that, since it is thicker back by the chamber.

      That said, it's something I intend to test out.

    2. If your groups are opening it will not be the rifle. Slow back down and work the basics and then work your speed back up. It is not the rifle that is not holding the group, it is the shooter!!!!

    3. 3rd man -

      While I agree that the guy pulling the trigger is far more likely to be the limiting factor, with optics being next in line - for example, an 8 moa red dot is gong to become a group size bottle neck - there is some legitimacy to barrels becoming more inconsistent as they heat up. Old mini 14s for example used to be notorious for this. That said, I have not heard of this being an issue with lightweight profile AR barrels, and especially BCMs proprietary ELW profile, which is designed to handle heat more like a standard government profile than a conventional lightweight profile.

      Also - if I really need to dump a couple hundred down range, I am not particularly concerned if the group size opens up a couple MOA. Again, to your point, the shooter and combat conditions are going to have a much greater negative impact in accuracy.

    4. Correct on using crappy equipment. That is why I am not a build your AR for under 500 guy. You get what you pay for. As the barrel heat issue that goes back to training and fire management. You can shoot 12 to 15 rounds a minute 24 hours straight without heat issues. On a mag dump if your all over the target, than it is the trigger puller not the gun, because when your dumping a mag it is usually 15 yards. That is why I said slow down and return to the basics and then build your speed back up. Just my 2cents!

    5. Should say "15 yards and closer".

    6. Oh, one thing I do like your setup. BCM makes some good stuff. Travis Haley was running a similar setup from BCM but with a Mico in the recent class I attended.

  4. The new tactical hotness is running a 13-15" rail (if not longer, like the LVOA rails) with 1-6x. 1-6x; so hot right now.

    1. Would love to throw a quality 1-6 on it, but 1k to 2k ain't in the budget right now.

      Delete
    2. Primary Arms 1-6x ACSS is $269 and rivals glass 2-3x its price range.

  5. Very cool rifle. There are a lot more quality low variable power optics out there than a few years ago. The Burris MTAC 1-4 is awesome, hell for stout (John Mosby had one drop out of a jeep doing 60 and the only impact was you couldn't adjust a windage knob by hand) and the glass is as good as an ACOG or VXI series Leupold for $350ish.

    Vortex put out a new 1-6 at Shot Show that is running about 4 bills.

    I truly believe the low power variable is the most versatile optic out there. The difference between an illuminated 1x scope vs a red dot at CQB is negligible but the magnification at distance for accuracy and target identification is so huge. Even 1-4 is very valid from 0 to 400m or so.
